Now, here’s the good news<br />

A s<br />

I write this, one year has passed since the collapse of investment<br />

banking firm Lehman Brothers, which sent a shock wave around<br />

the world followed by financial panic and distress. The date was<br />

Septembe r 15, 2008 – a day that many of us will refer to as the start of<br />

the worst recessi on in modern history. Since then, it seems that every<br />

time we open a newspaper, visit a website or turn on the TV we are<br />

confronted by more bad news about the world economy. It’s almost as<br />

if we have come to expect it, along with our morning coffee.<br />

Well, here’s some good news. Even though many of our customers<br />

still face some of their toughest challenges, they will be pleased to<br />

know that <strong>Atlas</strong> <strong>Copco</strong> is on their side and is ready and willing to lend<br />

a helping hand. In a downturn, and especially one as serious as this, we<br />

all know how hard it can be to keep costs down while at the same time<br />

invest in the future. Suitable financing can be difficult to obtain, even<br />

at the best of times, and that’s when we can offer our support.<br />

<strong>Atlas</strong> <strong>Copco</strong> Customer Finance, our in-house finance organization<br />

for <strong>Atlas</strong> <strong>Copco</strong> customers, is able to provide alternative financing to<br />

make it easier for mining and construction companies to get the equipment<br />

they need, when they need it. And with the strength of the worldwide<br />

<strong>Atlas</strong> <strong>Copco</strong> Group behind us, we can offer long term support and<br />

financing solutions designed to meet our customers’ individual needs.<br />

We know the realities of the mining and construction business and<br />

we have a great appreciation for what our customers are trying to<br />

achieve. By helping them to finance their equipment needs, we also<br />

enable them to benefit from the superior productivity that our products<br />

provide. In other words, we invest in our customers’ future success.<br />

However, it is important to understand that we are not a bank. Our<br />

mission, pure and simple, is to support our customers with financing<br />

alternatives in connection with the acquisition of <strong>Atlas</strong> <strong>Copco</strong> products,<br />

if they feel they need our assistance. It’s all about working together<br />

to find the best possible solution that allows our customers to<br />

acquire the technology they need to stay competitive.<br />

Over the years, we have assisted countless customers to secure the<br />

equipment they require through a variety of tailor-made financing<br />

agreements – Rudnik of Serbia, IESA of Peru, Coeur Mexicana of<br />

Mexico, Barminco of Australia and Navarrete Servicios Mineros of<br />

Chile – to mention just a few.<br />

On page 10 you can read about how we are working closely with<br />

Barminco to ensure that they get the equipment they need, now and in<br />

the future, both at home and abroad. And on page 16 we show how<br />

Navarrete Servicios Mineros has grown to become a leading specialist<br />

in its field. Naturally, like everyone else, I look forward to the day<br />

when business gets back to more favourable<br />

levels. But our long term commitment<br />

to our customers will remain the same. We<br />

will continue to do our utmost to support<br />

their needs for equipment and to offer our<br />

financing assistance whatever the eco -<br />

nomic climate.<br />

Pit Viper fleet excels as<br />

peÑasquito po<br />

In just 14 months the site of the Goldcorp Peñasquito Mine in the state of<br />

Zacatec as, Mexico, has been transformed from a flat, open valley into a mine<br />

producing more than 500 000 tonnes of rock each day. Its choice of equipment<br />

and service support has proven to be the perfect fit.<br />

Peñasquito is Mexico’s largest openpi<br />

t mine and comprises the Penasco<br />

and Chile Colorado/Azul deposits<br />

that contain gold, silver, lead and zinc.<br />

At an elevation of 1 900 m above sea<br />

level, the surface of the site is made up of<br />

approximately 30 metres of alluvium.<br />

The virtually flat topography has helped<br />

the mine carry out its development plan<br />

that includes moving large amounts of<br />

rock. “I’m used to mining in mountains<br />

so this is easy mining by comparison,”<br />

says Mine Manager Tim Collins.<br />

The company reports that annual production<br />

over the life of the mine (estimated<br />

to be 22 years) is expected to ramp<br />

up to approximately 500 000 ounces of<br />

gold, 30 million ounces of silver and<br />

more than 400 million pounds of zinc.<br />

The Peñasquito project is considered<br />

a total community improvement programme<br />

that includes educating future<br />

generations by building schools.<br />

When looking for potential employees<br />

in the surrounding area, Peñasquito<br />

found that most of the local inhabitants<br />

had no mining experience or even a driver’s<br />

license. Today, however, 70 percent<br />

of Peñasquito’s truck drivers are local<br />

women, many of whom had never driven<br />

before, and now work at the mine as a<br />

result of Goldcorp’s investment.<br />

In addition, operating millions of dollars<br />

of earth moving equipment required<br />

an intensive training programme before<br />

the workers entered daily production.<br />

Powerful fleet<br />

From the outset, it was the mine management’s<br />

vision to achieve a high level of<br />

production, but first it was necessary to<br />

find the right combination of equipment<br />

and support for the project.<br />

To drill and blast half a million tonnes<br />

of rock every day, the mine needed a special<br />

drilling fleet and rig management<br />

programme. The mine uses only <strong>Atlas</strong><br />

<strong>Copco</strong> drill rigs which include eight Pit<br />

Viper 351 blast hole drill rigs plus a DML<br />

and an ECM 590 for specialized tasks.<br />

Production hole size is 311 mm (12 ¼<br />

inches) for the 15 m (49 ft) bench height.<br />

Different types of <strong>Atlas</strong> <strong>Copco</strong> Secoroc<br />

Epsilon tricone bits are also used, depending<br />

on ground conditions. The entire<br />

drill string, including the pipe, stabilizers,<br />

bushings and subs are supplied by<br />

<strong>Atlas</strong> <strong>Copco</strong> Thiessen.<br />

Learning to operate the rig also<br />

require d extensive training, but it takes<br />

time to learn the ‘feel’ of the ground. To<br />

speed up this process, Peñasquito chose<br />

rigs with <strong>Atlas</strong> <strong>Copco</strong>’s Rig Control<br />

Syste m (RCS), which simplifies the<br />

drilling functionality for the operator.<br />

They have it all<br />

“These drills have it all,” says Mine<br />

Manager Collins. “The operator only<br />

needs to move it and level it and the rig<br />

drills its own hole.” Collins adds that<br />

he does have four experienced drillers<br />

who like to drill manually and they can<br />

match the auto-drilling performance.<br />

“There are times when the bit can take<br />

more down pressure and less rotation; a<br />

Mine Manager Tim Collins: “Technolog y<br />

is the future. The operator only needs to<br />

move it and level it and the rig drills its<br />

own hole.”<br />

skilled operator can feel that,” said<br />

Collin s.<br />

The Rig Control System (RCS),<br />

integrate s common drilling functions<br />

such as collaring a hole with low pressure<br />

air and down pressure, applying just<br />

the right amount of water and anti-jamming,<br />

with several high-tech options<br />

such as GPS hole navigation (for more<br />

informatio n, see Technically Speaking,<br />

page 18).<br />

Ensures efficiency<br />

RCS ensures efficient drilling, but many<br />

features are also for the safety of the<br />

miners and equipment. These include<br />

jack and tram interlocks which ensure<br />

that the rig and tooling are secure before<br />

a rig can move.<br />

The mine has installed a complex dispatch<br />

system that integrates with the GPS<br />

on each haul truck, shovel, drill rig and<br />

every other piece of mining equipment.<br />

The entire operation is monitored from a<br />

control room where two dispatchers and a<br />

maintenance person watch and direct the<br />

activity in the mine.<br />

All data is recorded and is retrievable<br />

by those in the mine who need constant<br />

equipment information. However, the<br />

operation can also be monitored in real<br />

time through a web-browser interface<br />

anywhere in the world.<br />

Technology is the future<br />

“Technology is the future of mining,”<br />

continues Collins. “If you’re monitoring<br />

maintenance and operational data to this<br />

level, decisions are made when they need<br />

to be made. Mining is more efficient toda y<br />

than it once was – technology has a lot to<br />

do with that – and safety can only move<br />

forward at the same time.”<br />

When searching for the right equipment,<br />

Alan Hernandez, Project Engineer,<br />

Technical Services, and Tim Collins,<br />

spent seven months travelling around the<br />

world trying to decide which products<br />

would fit the programme. “There were<br />

some hard decisions, but for drill rigs it<br />

was always <strong>Atlas</strong> <strong>Copco</strong>,” said Hernande z.<br />

More time was spent debating which<br />

Atla s <strong>Copco</strong> drill models would best fit<br />

the plan.<br />

“We looked at feasibility studies,<br />

calculation s, pit design, tonnage – every<br />

scenario that would determine what would<br />

work best,” says Collins. “For most equipment<br />

it was a matter of elimination. The<br />

choice consistently came down to service<br />

and support, but with <strong>Atlas</strong> <strong>Copco</strong> there<br />

was no debate.<br />

“As far as drilling goes, everything<br />

here comes from <strong>Atlas</strong> <strong>Copco</strong>,” he adds,<br />

complimenting the speed and penetration<br />

rate of the Pit Viper 351. “The 351 will<br />

drill fifty holes per twelve-hour shift.”<br />

Drilling and blasting half a million tonnes of rock every day: The <strong>Atlas</strong> <strong>Copco</strong><br />

Pit Viper 351 drill rigs in operation at Penasquito.<br />

The fleet at Peñasquito drills an<br />

averag e of 2 300 to 2 500 holes per<br />

week. To keep ahead of the crushers,<br />

about 15 million tonnes of inventory<br />

are kept in the pit. “I like to keep at least<br />

a month ahead,” says Collins. This<br />

inventor y allows time to support the<br />

drills. “The maintenance plan includes<br />

having two or three rigs serviced for<br />

preventative maintenance. That takes<br />

care of normal wear and tear. I can say<br />

the Cummins engines in all our drill rigs<br />

are solid, they don’t even burn oil.”<br />

Close support<br />

In addition to parts and training,<br />

Xavier Garcia, <strong>Atlas</strong> <strong>Copco</strong>’s Key<br />

Account Manager for Goldcorp, personally<br />

handles drilling consumables<br />

at the mine. “Twice a month, Xavier<br />

spends nearly a week here analyzing<br />

bits. Sometimes it feels like he practically<br />

lives here,” says Collins. <strong>Atlas</strong><br />

<strong>Copco</strong>’s Marcus Pantoja and Octavio<br />

Garcia (Service Manager and Product<br />

Specialist) also play a key role,<br />

providing training, equipment start-up,<br />

commissioning and technical support.<br />

To date, the epsilon tricone bit line<br />

has changed from eH53CA to eH61-<br />

CA, eH62OA and eH64OA, to adjust<br />

to the rock formation. “We are constantly<br />

reviewing bit wear and performance.<br />

We’ll keep testing bits until<br />

we settle on the one that works the<br />

best,” he says. “A great advantage has<br />

been the use of the TeamAlloy Drill<br />

Pipe from <strong>Atlas</strong> <strong>Copco</strong> Thiessen, which<br />

seems to last foreve r.” M&C 3•09<br />

The Peñasquito mine will have a long<br />

life. As of December 31, 2008, proven and<br />

probable gold reserves totalled 17.4 million<br />

ounces. Silver reserves totalled 1 045.7<br />

million ounces, while lead and zinc stood<br />

at 7.07 million tonnes and 15.36 million<br />

tonnes respectively. Measured and indicated<br />

gold resources, inclusive of proven<br />

and probabl e reserves, increased 39<br />

percen t to 17.8 million ounces. Measured<br />

and indicated silver resources increased<br />

55 percent to 1.3 billion ounces.<br />

How the world’s largest underground<br />

silver mine uses raiseboring to boost<br />

efficiency in mine development.<br />

The Fresnillo Mine in Zacatecas produces<br />

ore containing an average of 500<br />

grams of silver per tonne with one vein,<br />

San Alberto, averaging 700 grams per<br />

tonne. The San Carlos vein has been mined<br />

for years, to a current total length of 5 km<br />

and an average of 500 grams per tonne.<br />

Martin Robledo, Mine Superintendent,<br />

puts the San Carlos vein into perspective:<br />

“When this six-kilometre long<br />

vein appeared at the 200 metre level, it<br />

was five metres wide and continues that<br />

way down to the 600 metre level.”<br />

The mine produces three million ounce s<br />

of silver per month from 8 000 tonnes of<br />

ore produced each day. Of this, 2 000<br />

tonnes are trucked through the San Alberto<br />

ramp and 2 000 tonnes and 4 000 tonnes<br />

respectively are hoisted via two separate<br />

shafts.<br />

For future growth, the mine is currently<br />

in the process of developing a new<br />

shaft consisting of two 3.6 m (12 ft) parallel<br />

raises, using a Robbins 73RH C commissioned<br />

in early 2009. The drilling of<br />

these raises, each totalling 530 m, has<br />

been extremely accurate. The first raise<br />

had a deviation of just 20 cm and of only<br />

3 cm on the second raise.<br />

on the rise<br />

Multiple mining methods are used<br />

and 30 cut-and-fill stopes and 20 longhole<br />

stopes are currently active. “From<br />

the time we begin developing a stope<br />

block it takes about a year before it’s in<br />

production,” says Robledo.<br />

The process of developing a long<br />

hole block includes multiple stopes<br />

about 200 m long, one above the other,<br />

up to 30 m. For long hole stopes,<br />

multipl e levels are mined simultaneously.<br />

Multiple stopes will be blasted at<br />

the same time, removing the ore from<br />

the lowest level.<br />

Raising efficiency<br />

Raiseboring is an important part of the<br />

mining cycle in long hole stoping. The<br />

raises are used to create slots which serve<br />

as starting areas for each new stope. In<br />

order to increase the efficiency and speed<br />

of this type of raising in the production<br />

areas, an <strong>Atlas</strong> <strong>Copco</strong> Robbins 34RH C<br />

QRS raiseborer was recently added to<br />

the mine’s fleet.<br />

This raiseborer was specially designe d<br />

to rapidly drill short and small diameter<br />

raises. It is the first raise drill to be designed<br />

with the transporter (diesel powered<br />

crawler) as an integrated part of the<br />

machine, and a drilling platfrom eliminating<br />

the need for a concrete pad.<br />

As of October 2009, the new unit had<br />

completed 15 raises. Of those, 10 were<br />

slots for the long hole production operation<br />

and five were ventilation holes. Once<br />

in position, the raisedrill is stabilized<br />

usin g stinger cylinders prior to drilling.<br />

Easy down-reaming<br />

The 34RH C QRS can bore a raise of 720<br />

mm in diameter, either by down-reaming<br />

a pilot hole or by back reaming a conventional<br />

raise to 1.2 m in diameter in<br />

most rock types.<br />

When down-reaming, a pilot hole is<br />

drilled to a lower level. The drill pipe is<br />

then removed and a Secoroc 720 mm<br />

down-reamer with three cutters is<br />

installe d. The pilot hole is then downreamed<br />

with the cuttings falling down<br />

the pilot hole.<br />

When the raise is complete, the pipe<br />

and reamer are pulled back to the raise<br />

drill and removed at the upper level, eliminating<br />

the need for operators to remove<br />

or install the bits at the lower level. On<br />

average, the raises are 24 m high but<br />

have gone as far as 30 m.<br />

“When the vein is less than three<br />

metres wide, we use the <strong>Atlas</strong> <strong>Copco</strong><br />

Simba 1254 with the COP 1238 tophammer<br />

and two-inch bits,” Robledo<br />

explains. If more than three metres, the<br />

Simba M4C with COP 44 ITH hammer<br />

and a 102 mm (4-inch) bit is used.<br />

The mine also has an <strong>Atlas</strong> <strong>Copco</strong><br />

Simba H252 and a Simba H262 as well<br />

as Diamec U6 exploration rigs.<br />

Robledo says that in the six months<br />

since the 34 RH rig started drilling, it has<br />

made the overall mine plan more productive.<br />

“During the drilling of the 15<br />

raises, totalling 450 metres, we have had<br />

no problems,” he says, adding that the<br />

Secoroc cutters will last for an estimated<br />

1 000 m before they have to be replace d.<br />

Fresnillo is said to produce more silver<br />

at a higher grade than any other mine<br />

and the end of its productive life is nowhere<br />

in sight. M&C 3•09<br />

A Mexican leader<br />

Raiseboring, as a method of driving various<br />

types of shafts, is well established in Mexico<br />

and <strong>Atlas</strong> <strong>Copco</strong> is a market leader with some<br />

40 units in operation in the country’s mines.<br />

These raiseborers, called <strong>Atlas</strong> <strong>Copco</strong><br />

Robbins, incorporate the very latest technology<br />

for quick-set up and push-button<br />

operatio n as well as high performance reamers<br />

and cutters from <strong>Atlas</strong> <strong>Copco</strong> Secoroc.<br />

Fresnillo PLC, which operates three mines,<br />

is a forerunner with six units of various types<br />

on site: a Robbins 73RAC and a 73RH C, two<br />

73RDC and two 34RH C QRS (Quick Raisebore<br />

Set-up).<br />

Since the mid-60s, <strong>Atlas</strong> <strong>Copco</strong> has produced<br />

some 420 raiseborers for driving shafts<br />

in a wide variety of mines around the world.<br />

Palmarejo maxi<br />

The Palmarejo Mine has been developed into a productive gold, silver, coppe r<br />

and lead operation in just 18 months. M&C finds out how grade control using<br />

reverse circulation drilling is helping to maximize ore recovery.<br />

When Coeur d’Alene Mines started<br />

developing the Palmarejo<br />

Mine, it took six to eight hours<br />

to drive to the site from the last community<br />

along the road, San Rafael. Today, it<br />

takes just three hours.<br />

Since the mine opened, just 18 months<br />

ago, the site has been transformed from a<br />

steep mountainous ravine into two highly<br />

productive open pits plus an underground<br />

operation with three portals – and<br />

looks to have a promising future.<br />

Two separate excavation areas are<br />

opening up the mountain from above,<br />

while long-hole stoping is carried out below<br />

the mountain’s base.<br />

Mine Manager Kerry Barker explains<br />

the mine’s approach to selecting the<br />

technology and mining methods used at<br />

Palmarejo. “Take the best mining methods<br />

and apply them,” he says. “It’s great<br />

to bring in fresh ideas from other places<br />

and we have great people here who have<br />

no problem with accepting new ideas.”<br />

<strong>Atlas</strong> <strong>Copco</strong> equipment is involved in<br />

every aspect of mine development and<br />

exploration. Barker says: “We like having<br />

<strong>Atlas</strong> <strong>Copco</strong> around here and that<br />

includes the great service.” The open pit<br />

production drilling is done by the <strong>Atlas</strong><br />

<strong>Copco</strong> DM45 high pressure DTH drill<br />

rigs which are highly mobile on the<br />

benches, while <strong>Atlas</strong> <strong>Copco</strong> Boomer and<br />

Simba rigs are used for the underground<br />

long-hole stope mining with cement<br />

backfill.<br />

Reverse circulation<br />

Palmarejo uses two <strong>Atlas</strong> <strong>Copco</strong> ROC<br />

L8 RC drill rigs to perform reverse circulation<br />

drilling (RC) ahead of the open pit<br />

operation. RC drilling involves forcing<br />

air down the centre of a double-wall drill<br />

pipe with the cuttings returning up the<br />

inside of the double pipe. These cuttings<br />

are then sent through a separator that allows<br />

samples to be taken at specific drilling<br />

depths. The samples are bagged and<br />

sent to a laboratory for analysis.<br />

The Secoroc RC50 reverse circulation<br />

hammer used on the ROC L8 rigs<br />

is available in two versions, one for<br />

deep hole exploration and one optimized<br />

for in-pit grade control with corresponding<br />

bit options. The hammer<br />

features a unique, easy to service collector<br />

tube that can be replaced without<br />

disassembling the hammer. The impact<br />

frequency of the RC hammer is up to<br />

34 percent higher than competitor models<br />

and gives more rapid drilling.<br />

The open pit operation recovers 3 000<br />

tonnes of ore per day and moves a total<br />

of 1.5 million tonnes of waste per month.<br />

The underground mining operation includes<br />

5.5 km of drift at a 5 x 5 m heading,<br />

advancing 30 m or 2 000 tonnes per<br />

day, for a total of 100 000 tonnes per<br />

month. And there are two places for all<br />

this rock to go – the mill or waste pile.<br />

As General Manager Stewart Mathews<br />

points out: “It only takes 20 trucks going<br />

to the wrong place to know that reverse<br />

circulation drilling is worth it.”<br />

Working ahead of the operation by<br />

about three months, the two ROC L8 RC<br />

rigs drill 140 mm holes (5 ½ inches) to<br />

depths of 7, 10 and 18 m. Each rig averages<br />

12 holes per day and the plan is to<br />

complete a total of 600 holes per bench.<br />

RC the way to go<br />

“We use the ROC L8 for horizontal drain<br />

holes too, but the rig is made for RC<br />

drilling,” says Mathews. “In-pit grade<br />

control is the way of the future, I can’t<br />

understand why it isn’t done everywhere.<br />

It’s the only way to go.”<br />

When RC drilling, the Secoroc RC50<br />

hammer drills 18 m penetrating and sampling<br />

three bench depths at once. The<br />

holes are drilled on a 10 x 10 m pattern


mizes quality<br />

as reverse circulation drilling pays off<br />

In the bag: Samples of cuttings from the ROC L 8 and its Secoroc<br />

RC50 reverse circulation hammer, are collected for analysis. The<br />

results help the Palmarejo Mine to optimize its ore recovery.<br />

with the ore zone over-drilled by 30 percent.<br />

The holes are drilled at 56 degree<br />

angles and the veins run at a 57 degree<br />

dip. “We are actually drilling two veins,”<br />

says geologist Arturo Soto.<br />

“We have great<br />

people who<br />

have no trouble<br />

accepting new<br />

ideas.”<br />

Kerry Barker,<br />

Mine Manager,<br />

Palmarejo Mine.<br />

The separate veins, named La Blanca<br />

and La Prieta, are a short distance apart,<br />

joining towards the west before separating<br />

again. “The hanging wall between<br />

the veins can present economic grade<br />

ore,” adds Soto. Taking samples allows<br />

the mine to assess the quality of the ore<br />

as they drill through it.<br />

For the most part, the RC drilling<br />

presents few problems. The only challenges<br />

encountered being some shale<br />

above the ore body and occasional water.<br />

Shale creates some difficulty in drilling,<br />

but hitting water is more problematic for<br />

the drillers.<br />

When water is encountered, the<br />

driller must clean the air holes in the bit<br />

and hammer between holes to ensure<br />

the integrity of the samples. “We have<br />

3D modelling of the mine but sometimes<br />

you just can’t be sure, and RC<br />

drilling makes you sure,” says Soto.<br />

The RC drilling is used to measure the<br />

ore body and test the gold, silver, lead and<br />

copper in the ore, but it also has another<br />

important use. “Just yesterday we ran into<br />

two voids when drilling,” points out Soto.<br />

Locating voids as well as soft and unconsolidated<br />

rock is an important use of the<br />

ROC rigs in this formation. The voids are<br />

mapped to ensure safe drilling for the<br />

DM45 rigs that will follow.<br />

It takes operator Oswaldo Gaxiola and<br />

assistant Victor Hernandez about 30 minutes<br />

to drill and bag each hole. “When I<br />

hit soft rock I have to back off and clean<br />

the hole, then go back in slowly,” said<br />

Gaxiola, who learned to drill just two<br />

months ago and finds the ROC L8 RC<br />

easy to operate. Gaxiola says he likes the<br />

auto-drill functionality on the ROC L8<br />

because it does most of the work and prevents<br />

jamming in the hole.<br />

In an average shift, about twelve, 18 m<br />

holes are drilled per rig. Soto points out<br />

that he is more concerned with producing<br />

quality samples than simply fast drilling.<br />

Palmarejo was targeted for a 10-year<br />

life with a yearly production of 110 000<br />

ounces of gold and nine million ounces<br />

of silver. Stewart Mathews is convinced<br />

RC drilling is the best solution for managing<br />

the mine development and concludes:<br />

“It ends all arguments about<br />

reconciliation. Quality samples are<br />

needed to make quality decisions. RC<br />

drilling for grade control is the only<br />

way to go.” M&C 3•09<br />

FINANCING<br />

FOR THE FUTURE<br />

Barminco of Australia has<br />

the key to funding its equipment needs<br />

Despite the global economic crisis, many mining and construction<br />

compani es around the world are still able to invest in the future – thanks<br />

to tailor-made financing solutions from <strong>Atlas</strong> <strong>Copco</strong>. Mining contractor<br />

Barminco is a typical example.<br />

B<br />

arminco is one of Australia’s leading<br />

mining contractors with operations<br />

at 18 sites across the continent<br />

as well as two others overseas. The<br />

company is well known for its productivity<br />

performance both above and below<br />

ground – and for its insistence on using<br />

the best technology available.<br />

However, when it was time for the<br />

company to renew its equipment fleet<br />

this year, the tough economic conditions<br />

caused by the global financial crisis<br />

require d a more creative approach to<br />

satisf y its financing needs.<br />

With major undertakings in Australia<br />

and a new project about to get under way<br />

in Africa, Barminco needed to increase<br />

its fleet of <strong>Atlas</strong> <strong>Copco</strong> equipment. But<br />

instead of seeking funding from traditional<br />

sources – mining financiers, banks<br />

and the like – the company asked <strong>Atlas</strong><br />

<strong>Copco</strong>, a preferred Barminco supplier, to<br />

come up with an attractive solution.<br />

The result is a multi-million dollar<br />

credit and commercial hire purchase<br />

facilit y arranged through <strong>Atlas</strong> <strong>Copco</strong><br />

Customer Finance (ACF), the <strong>Atlas</strong><br />

Copc o Group’s in-house finance compan<br />

y (see box).<br />

Close co-operation<br />

The agreement was completed in February<br />

2009 and immediately paved the way<br />

for the delivery of new MT6020 trucks<br />

and Diamec MCR rigs for deployment in<br />

Australian mines.<br />

Theresa Mlikota, Chief Financial Officer<br />

at Barminco, says these special arrangements<br />

with <strong>Atlas</strong> <strong>Copco</strong> have been<br />

instrumental in enabling the company to<br />

maintain its high quality services to its<br />

customers.<br />

Mlikota, who has more than 20 years’<br />

experience in structured financing, explains<br />

the background leading up to Barminco’s<br />

decision.<br />

“This funding is<br />

very flexible and<br />

tailor-made to<br />

our needs.”<br />

Theresa Mlikota,<br />

Chief Financial Officer,<br />

Barminco.<br />

“The recent uncertainty in capital<br />

markets has resulted in many financiers<br />

exiting the Australian market,” she says.<br />

“As a result we knew that financing<br />

would be critical to Barminco being able<br />

to continue delivering quality services to<br />

our own customer base.<br />

“<strong>Atlas</strong> <strong>Copco</strong> understands the contract<br />

mining business and is always keen<br />

10


to understand Barminco’s requirements.<br />

This sets them apart from traditional<br />

financin g, which is often reactive. In<br />

additio n, <strong>Atlas</strong> <strong>Copco</strong>’s focus on customer<br />

service means we often work together<br />

to deliver viable solutions to operate<br />

and fund our business.<br />

“In this case, the <strong>Atlas</strong> <strong>Copco</strong> custome r<br />

service team has worked closely with<br />

Barminco to deliver our operational requirements<br />

and with our financing team<br />

to effect a sale. The financing offered by<br />

<strong>Atlas</strong> <strong>Copco</strong> is not a definitive driver in<br />

our business but it is certainly a key driver<br />

and we are very happy with how it works.”<br />

Flexible and tailor-made<br />

Barminco has been using hire purchase<br />

and lease-styled financing for a long time<br />

as these methods suit its clients and its<br />

own cash flow. So why is the <strong>Atlas</strong> Copc o<br />

agreement especially attractive<br />

“Firstly,” Mlikota says, “this funding<br />

is very flexible, and secondly the terms<br />

are tailor-made to our practical needs<br />

and working realities.”<br />

She continues: “<strong>Atlas</strong> <strong>Copco</strong> has<br />

analyzed what we need and when we<br />

need it and has linked the funding to<br />

the life cycle of the equipment and a<br />

performance guarantee. This is very<br />

favourable for both Barminco and<br />

<strong>Atlas</strong> <strong>Copco</strong>.<br />

“In supporting us this way, <strong>Atlas</strong><br />

Copc o has shown that it is willing to play<br />

a much stronger role in supporting our<br />

business than a conventional financier<br />

which has been especially useful for us<br />

Barminco – a leader down under<br />

Barminco was established in 1989 and is one of<br />

Australia’s leading hard rock, underground mining<br />

contractors. With more than 1 500 employees<br />

and one of the largest fleets of underground mining<br />

equipment in Australia, the company aims to<br />

deliver high productivity while minimizing the cost<br />

of production in the mining of nickel, gold, copper,<br />

lead and zinc.<br />

Barminco prides itself on its leading market<br />

position and long-term relationships with many of<br />

the world’s largest mining companies, including<br />

at this time when financing is difficult.”<br />

<strong>Atlas</strong> <strong>Copco</strong> has been supporting<br />

Barminco since 2006 and the new agreement<br />

clearly further cements the relationship<br />

between the two companies.<br />

Rod Herman, Sales Manager, Customer<br />

Finance, Pacific and South East Asia,<br />

“This has<br />

definitely added<br />

to the ease of<br />

business.”<br />

Rod Hermann,<br />

<strong>Atlas</strong> <strong>Copco</strong> Customer<br />

Finance, Australia.<br />

points out: “This shows that despite the<br />

tough times that have been experienc ed<br />

over the last 12 months or so, <strong>Atlas</strong> <strong>Copco</strong><br />

New kid on the block: This wheel-based<br />

Diamec MCR (Mobile Carrier Rig) has been developed<br />

together with Barminco to meet demands for<br />

greater flexibility in underground core drilling.<br />

Previously available only on skids, the rig can move<br />

around in less than a quarter of the time needed<br />

for a skid-based rig. With no need for disassembly<br />

or transport assistance, it helps lead times for mining<br />

operations to be further reduced.<br />

DRILLING FOR P<br />

The town of Boyabat, northern Turkey is located on the ancient<br />

and famous Silk Road. But it is a more modern construction that is<br />

putting the town on the map today – the Boyabat dam.<br />

ON THE<br />

12<br />

The town of Boyabat (pop. 25 000)<br />

in northern Turkey, was once an important<br />

trading post on the ancient<br />

Silk Road that once brought exotic goods<br />

such as silks, spices and gemstones from<br />

the East to Europe and beyond. These<br />

days, it is still a centre of trade, serving<br />

as a bustling commercial hub for more<br />

than 100 surrounding villages.<br />

But it is not just the sound of traders,<br />

market-goers and troubadours that can<br />

be heard in the Kizilirmak valley today<br />

– the sound of construction work at the<br />

USD 1.2 billion Boyabat dam is also<br />

now a regular feature of daily life.<br />

Construction of the 510 MW Boyabat<br />

dam and hydropower station on the nearby<br />

Kizilirmak River, started in 2008 and<br />

is due for completion in 2012. The dam<br />

will be the third on the river and lies<br />

approximate ly 30 km from Boyabat and<br />

123 km from the Black Sea.<br />

Once finished, it will stand at a height<br />

of 195 m from its foundation and will<br />

have a crest of 262 m spanning the<br />

Kizilirm ak valley. The dam is ex pected<br />

to produce 1.5 billion kWh per year for<br />

distribution to cities across the country.<br />

The dam is being constructed by the<br />

Turkish company, Dogus Insaat, and<br />

involv es drilling a total of 600 000 m<br />

over three years. Of this, 400 000 m will<br />

be drilled in a nearby quarry for concrete<br />

production and 200 000 m will be drilled<br />

in pre-splitting holes. Some 13 million<br />

tonnes of excavated limestone will be<br />

produced from the quarry. A total of<br />

1 000 people are working on the project,<br />

including sub-contractors.<br />

The environmental impact of the<br />

operatio n is being monitored by the<br />

Ministr y of the Environment, a safety<br />

team from Dogus Insaat (working to ISO<br />

14001 and 18000 procedures) and the<br />

owner of the project, Boyabat Elektrik<br />

Uretim ve Tic.Ltd.Sti.<br />

Proven performance<br />

The drilling fleet at Boyabat consists of<br />

four <strong>Atlas</strong> <strong>Copco</strong> ROC D7 and four ROC<br />

203 rigs. Dogus Insaat had previously


An artist’s impression of the finished dam.<br />

TURKISH SILK ROAD<br />

used <strong>Atlas</strong> <strong>Copco</strong> surface drill rigs on<br />

anothe r project, a highway construction<br />

job in Morocco, where two ROC D7 rigs<br />

were used. This experience convinced the<br />

company that the same rigs would have<br />

the capacity and performance to cope<br />

with the Boyabat dam project.<br />

Another factor in choosing these rigs<br />

was <strong>Atlas</strong> <strong>Copco</strong>’s parts, service and<br />

maintenance capacity which would be<br />

essential given that the Boyabat dam site<br />

is remote – 700 km from Istanbul and<br />

400 km from Ankara.<br />

The rigs drill 89 mm holes for production<br />

drilling and 70–76 mm holes for<br />

presplit drilling. Additionally, a sub-contractor<br />

is operating two ROC D7-11 rigs<br />

fitted with COP 1840 rock drills and<br />

drilling is carried out 22 hours per day.<br />

The teams work 14 x 11-hour shifts per<br />

week. The blasted rock is removed with<br />

back-hoe excavators, loaded onto trucks<br />

and transferred to the dump site.<br />

For production drilling, a 2.5 x 3 m<br />

drilling pattern is used with an inclination<br />

of 4:1, and an inclination of 1.36:1<br />

for presplitting. Bench heights for production<br />

drilling vary from 6 –12 m.<br />

Durin g an average shift, the ROC D7<br />

rigs achieve 300 m per rig per shift for<br />

production drilling and 250 m per rig per<br />

shift for presplitting.<br />

Quarry Operation Manager, Can<br />

Celiksırt says: “We are very satisfied<br />

with the hole quality in such tough terrai n<br />

– especially in presplitting holes where<br />

we faced big problems because of the inclination<br />

of the bench.” Celiksırt designe d<br />

the software, DelPat v6.0, used to design<br />

the drilling pattern at the site.<br />

Presplit drilling solution<br />

The initial challenge, faced by the drill<br />

rigs and operators was encountered on<br />

the pre-split holes, spaced every 70 cm.<br />

The rock shelf was specified at 40 cm<br />

wide or less, with the 7 m holes drilled at<br />

an inclination of 40 degrees from the<br />

horizontal and it was difficult to place<br />

the rig close enough to the slope (the<br />

shelf was specified at 40 cm so that the<br />

steps created on the hillside would be<br />

minimal). The position of the rigs’ rod<br />

handling carousels and hydraulic valve<br />

groups meant the rig could only drill the<br />

required inclination and hole depth on 70<br />

cm benches.<br />

A sales and service team from <strong>Atlas</strong><br />

<strong>Copco</strong> decided to change the feeds on<br />

two of the ROC D7 rigs used for presplitting<br />

with the company’s underground<br />

rock drilling version, the BMH 6821.<br />

This allowed the operators to position the<br />

feed closer to the slope. As the feed was<br />

longer than the previous version, the rodhandl<br />

ing carousel could also be removed.<br />

After this modification, the required<br />

inclina tion and hole depth was achieved<br />

Symmetrix the solution<br />

as IKEA goes geothermal<br />

Sixty wells, each 200 m deep were drilled into bedrock<br />

in just ten days – part of a geothermal energy system<br />

for the new IKEA store in the city of Tampere, Finland.<br />

Challenging ground conditions were overcome by<br />

Symmetrix drilling technology.<br />

When IKEA’s new store opens in<br />

Tampere, Finland, the 37 500 m 2<br />

building will be heated and cooled using<br />

only geothermal energy. The project is<br />

the largest of its kind in the country and<br />

part of IKEA’s long-term programme to<br />

have all IKEA buildings powered by 100<br />

percent renewable energy.<br />

Geothermal energy is solar energy,<br />

stored in the bedrock. Using heat pumps,<br />

this energy is collected from the ground<br />

via holes and used for heating buildings<br />

and water. And the popularity of this environmentally-friendly<br />

energy source is<br />

increasing rapidly; in Finland, 7 500<br />

ground source heat pumps were sold in<br />

2008 – a 42 percent increase on the previous<br />

year.<br />

Loose ground<br />

After the groundwork was completed at<br />

the site of the new IKEA store, the surface<br />

consisted of a three-metre layer of<br />

unconsolidated rock. Drilling the 60 energy<br />

wells would require a system that<br />

could both drill and advance a casing<br />

pipe at the same time.<br />

The contract to drill the 60 energy<br />

wells was awarded to drilling contractor<br />

Suomen Porauspalvelu. With each hole<br />

200 m deep, a total of 12 km of drilling<br />

was required. The wells were designed in<br />

“We are<br />

pleased we<br />

could meet this<br />

challenging<br />

deadline.”<br />

five rows, each consisting of 12 wells.<br />

The wells in the central row were<br />

drilled vertically. The two rows either<br />

side of this row were drilled with an<br />

inclination of five degrees. The wells<br />

in the outermost two rows had an<br />

inclinati on of ten degrees away from<br />

the centre row. The holes were drilled<br />

in this way to ensure sufficient space<br />

between each hole at the 200 m depth,<br />

regardless of deviation.<br />

A case for Symmetrix<br />

A range of <strong>Atlas</strong> <strong>Copco</strong> products were<br />

selected for the project which included<br />

the compressors, drill rods, Symmetri x<br />

P140/5-115 casing advancement system,<br />

Secoroc 115 mm bits, Secoroc<br />

COP44 and TD40 DTH hammers.<br />

Jukka Ahonen, General Manager,<br />

<strong>Atlas</strong> <strong>Copco</strong> Rotex explains that the<br />

Symmetrix system was ideally suited<br />

to the ground conditions. “At this site,<br />

there was an unconsolidated layer of<br />

rock created by blasting and excavation<br />

works,” he explains. “Passing<br />

this layer quickly and efficiently was<br />

the key to achieving high productivity.”<br />

The Symmetrix system consists of<br />

drill bits and a casing shoe that is welded<br />

to a casing tube. Using percussive<br />

drilling, the drill bit drills a hole large<br />

enough for the casing tube to advance<br />

down the hole. With this system, it is<br />

possible to install casing tubes through<br />

hard and rocky unconsolidated material<br />

and into the bedrock. The contact area<br />

of the casing tube and bedrock is sealed<br />

in order to prevent surface water entering<br />

the well.<br />

Rapid drilling<br />

Drilling began with the Symmetrix<br />

system in August installing permanent<br />

casings with an outer diameter<br />

140 mm. After this, drilling was carried<br />

out through the cased hole using<br />

Secoroc 115 mm bits until the final<br />

depth was reached.<br />

The time schedule for the assignment<br />

was tight and Suomen Porauspalvelu<br />

put its entire fleet of three<br />

drilling rigs onto the project. The<br />

work, including 12 km of drilling was<br />

completed in just ten working days.<br />

Tor Enqvist, Joint Owner, Suomen<br />

Porauspalvelu, says: “A condition of<br />

this contract was that it could be completed<br />

within a tight timeframe. We<br />

are pleased to have managed with this<br />

challenging schedule. Since 2007,<br />

when we started our company, we<br />

have chosen to invest in modern, high<br />

quality tools and machines. By doing<br />

so we can meet our customer expectations,<br />

both in terms of reliability and<br />

productivity.” M&C 3•09<br />

The company now has a fleet of 20<br />

<strong>Atlas</strong> <strong>Copco</strong> ROC L8 rigs which in 2008<br />

achieved a record average performance<br />

of 100 000 drilled metres per month.<br />

Jaime Navarrete says: “Our success is<br />

the result of a combination of a strong<br />

customer focus and the latest drilling<br />

technology for reliable production, supported<br />

by a large fleet of drill rigs. This is<br />

in line with our policy to always offer best<br />

practice in the services we provide.”<br />

The skill of the company’s rig opera-<br />

tors also plays a major role. “They are<br />

well trained and bring a lot of experience<br />

and expertise to every site they work on<br />

– they are critical to our success. In addition<br />

we offer the latest technology and<br />

our drilling capability is supported by a<br />

spare parts contract with <strong>Atlas</strong> <strong>Copco</strong> and<br />

a ‘pay-as-you-go’ drilling consumables<br />

con tract with Secoroc.<br />

“Reliable support from key suppliers<br />

has always been important to us,” he<br />

continues. “Right from the start, we had<br />

that support from <strong>Atlas</strong> <strong>Copco</strong> and we<br />

still have it today. I think that in every<br />

commercial relationship, trust is a must,<br />

and every time I have contact with <strong>Atlas</strong><br />

NEW PLATFORM DRIVES<br />

AUTOMATED<br />

DRILLING<br />

By Dustin Penn<br />

Combining the latest computer and IT technology, <strong>Atlas</strong> <strong>Copco</strong>’s latest RCS-equipped<br />

blasthol e drill rigs feature modularized software and hardware that can easily be upgrade d<br />

to offer increased functionality as well as a wealth of automation options.<br />

<strong>Atlas</strong> <strong>Copco</strong>’s current Pit Viper drill<br />

rigs showcase the leading-edge<br />

computer-aided automation technology<br />

that has been deployed across the<br />

company’s range of drill rigs.<br />

The common platform makes it easier<br />

for customers to familiarize themselves<br />

with <strong>Atlas</strong> <strong>Copco</strong> technology across a<br />

range of products. In turn, this simplifies<br />

operation, maintenance, servicing and<br />

training. It also helps to facilitate continuous<br />

product development and the<br />

rapid application of new technology<br />

across the entire product range.<br />

The Rig Control System (RCS) and<br />

Auto interlock button. Press<br />

and hold this first and then<br />

choose one of the following<br />

auto functions.<br />

Using multilever rocker switch.<br />

Autolevels up for<br />

down in drill mode.<br />

Autodrill. Drills to predefined<br />

depth and returns head to propel<br />

safe position. Anti-jam, void detection<br />

and so on in drill mode.<br />

Future option. Auto tramming or<br />

autonomous operation.<br />

CAN-bus technology provides the backbone<br />

of the new system, bringing flexibility<br />

and expandability to the RCS and<br />

means that new modules can be added<br />

anywhere along the data bus, without<br />

adding extra cables.<br />

Easily upgraded<br />

Customers can start with a low level of<br />

automation and as their requirements<br />

change, they can upgrade. The RCS allows<br />

new functionality to be added,<br />

without major rebuilding of the rigs.<br />

Every Pit Viper rig can be equipped<br />

with RCS Basic. The system also offer s<br />

Fingertip control: RCS automated function buttons on the operator’s panel.<br />

a range of optional technologies including<br />

auto-levelling, auto-drilling, GPS<br />

hole navigation, Remote Rig Access<br />

and communication, wireless remote<br />

tramming and Measure While Drilling<br />

data log files, all supplied in IREDES<br />

format (International Rock Excavation<br />

Data Exchange Standard).<br />

In addition to the interlock features<br />

that ensure safe operation and tramming<br />

of the Pit Viper, the Rig Control System<br />

is also packed with capabilities to optimize<br />

drilling performance.<br />

Automated operations<br />

In scenarios that involve drilling through<br />

several rock types, the RCS’s Autodrilling<br />

function reacts to feedback from the<br />

rig’s sensors. Auto-drilling imitates the<br />

reactions of an experienced operator by<br />

adjusting the drilling parameters according<br />

to the drilling conditions.<br />

The system detects the bit’s contact<br />

with the rock and controls the air, water,<br />

rotation and feed to collar the hole. Next,<br />

these variables are adjusted as drilling<br />

commences and the optimum pulldown<br />

pressure and rotation are applie d.<br />

The system will drill as fast as possible<br />

without stalling the rotation or getting<br />

stuck. When the specified depth has<br />

been achieved, the hole is automatically<br />

flushed and the bit is retracted to the<br />

tram-safe position.<br />

To increase the quality of the drill<br />

rig’s set-up at the hole, the RCS platform<br />

Major advantages: Thanks to the new<br />

Rig Control System, every Pit Viper can<br />

now be equipped with auto-levelling,<br />

auto-drilling, GPS hole navigation, Rig<br />

Remote Access and communication,<br />

wireless remote tramming, Measure<br />

While Drilling data log files and IRE-<br />

DES format.<br />

can offer an auto-levelling option. This<br />

feature automatically levels the drill rig,<br />

reducing wear and tear of the rig’s structure<br />

by limiting torsion of the frame and<br />

tower during the levelling and de-levelling<br />

process.<br />

The accuracy of the system depends on<br />

the ground conditions but a typical levelling<br />

sequence on normal ground is achieved<br />

in less than 35 seconds and to an accuracy<br />

(in pitch and roll) of 0.2 degrees.<br />

The Rig Control System’s GPS hole<br />

navigation feature allows holes to be positioned<br />

with an accuracy of +/– 10 cm.<br />

The system ensures that the blastholes<br />

are accurately located according to the<br />

blast pattern in terms of both location<br />

and drilled depth.<br />

A drill plan, containing the mine’s<br />

coordinate s, is imported and the position<br />

of the bit, relative to the plan, is displayed<br />

in real time. The integration of<br />

the GPS to the rig’s RCS control system<br />

is via a standard RS serial link.<br />

Advanced communication<br />

<strong>Atlas</strong> <strong>Copco</strong>’s Rig Remote Access<br />

(RRA) technology allows the drill rig to<br />

be connected to a worksite’s computer<br />

network, again operating via the RCS.<br />

The system consists of a communication<br />

server and a network adapter and<br />

provides the user with three functions; a<br />

web server that can be accessed by any<br />

standard web browser, an FTP server<br />

for file transfer and a server process that<br />

enables data to be integrated into the<br />

user’s administrative systems and databases.<br />

The system uses standard communication<br />

protocols such as TCP/IP<br />

and PPP.<br />

Using the wireless network, working<br />

procedures are simplified and new capabilities<br />

are available to the mine’s planning<br />

organization. Work orders that were<br />

previously distributed before the shift<br />

bega n can now be distributed instantly<br />

and directly to the rig, creating more flexibility<br />

and adaptability in production.<br />

Computer-designed drill plans that<br />

were previously loaded manually into<br />

the rig’s RCS can now be transmitted<br />

wirelessly, saving time and allowing last<br />

minute changes to the drill plan.<br />

The system also allows drill logs to be<br />

transferred as soon as the round or individual<br />

blasthole is completed. This<br />

means that geological and geomechanical<br />

data can be instantly shared within<br />

the organization and that the drilling and<br />

blasting plans can be adapted, immediately<br />

and as required.<br />

Another key benefit of RRA is the<br />

ability to remotely monitor the status of<br />

the rig in real time. It also means that<br />

troubleshooting can be performed re-<br />

mote ly by specialized technicians at the<br />

mine or <strong>Atlas</strong> <strong>Copco</strong>.<br />

Remote control capability<br />

The Rig Control System’s teleremote feature<br />

uses the mine’s wireless network, either<br />

2.4 or 5.2 GHz frequency and allows<br />

an operator to operate the drill remotely,<br />

including the drilling, levelling, tramming<br />

and GPS hole navigation functions.<br />

A dedicated communication channel,<br />

guaranteeing the bandwidth and response<br />

required for real time operation of the rig,<br />

is required. The Teleremote module includes<br />

a dedicated safety system, independent<br />

of the RCS. If communication is<br />

lost between the remote operator and the<br />

rig, it will shut down. Additional safety<br />

systems, such as those that detect people<br />

moving into the rigs’ working area, should<br />

also be used and combined with the<br />

mine’s own safety regime. M&C 3•09<br />

NEW SOLUTION<br />

for rapid micropiling<br />

<strong>Atlas</strong> <strong>Copco</strong> has launched a new<br />

self-drilling micropile – the T111 –<br />

that drills and reinforces the hole in<br />

a single drilling operation.<br />

P<br />

rimarily aimed at supporting unconsolidated<br />

soil formations such<br />

as sand and gravel, <strong>Atlas</strong> <strong>Copco</strong>’s<br />

new MAI SDA T111 self drilling technology<br />

is ideal for a wide range of challenging<br />

micropiling applications.<br />

The system consists of a 111 mm<br />

(4.3") diameter hollow threaded rod with<br />

a sacrificial drill bit. Thanks to the full<br />

length rod thread and extension couplings,<br />

the flexible system allows the rod<br />

length to be easily adjusted to the site’s<br />

requirements.<br />

A selection of drill bits means the T111<br />

micropile system is able to drill through a<br />

wide range of material from sand and clay<br />

to rock. The piles work well as both tension<br />

and compression piles and can be<br />

installed on a vertical or inclined angle to<br />

provide grouped pile solutions.<br />

Faster installation<br />

Installation of conventional micropiles,<br />

for example drilled casings, require up to<br />

three separate operations. The T111<br />

minimizes the total installation time and<br />

increases productivity. Experience of installing<br />

<strong>Atlas</strong> <strong>Copco</strong>’s existing 76 mm<br />

self-drilling system has demonstrated<br />

“The T111 system<br />

is ideal for<br />

a wide range of<br />

applications.”<br />

Mark Bernthaler,<br />

Geotechnical Sales and<br />

Applications Manager,<br />

<strong>Atlas</strong> <strong>Copco</strong>.<br />

that it is not unusual for an operator to<br />

install 25 to 30, 15 m-long piles per day.<br />

During installation, cement grout is<br />

simultaneously injected into the rod,<br />

out through the bit and distributed evenly<br />

into the surrounding ground. The rod<br />

and bit are then left in place to act as the<br />

pile’s reinforcement element. Once the<br />

cement sets, the ground consolidates and<br />

forms a friction pile.<br />

With only light equipment needed<br />

for installation of the T111 and with no<br />

need to use large concrete mixing<br />

trucks, less impact is made on the surrounding<br />

area in terms of exhaust fumes,<br />

noise pollution and vibration. With the<br />

use of easily manoeuvrable rigs and<br />

only a few steps of installation, the operator<br />

is exposed to as few potentially<br />

harmful operations as possible.<br />

PR<br />

New Simba offers more<br />

for production drilling<br />

DUCTS<br />

PROGRESS<br />

New solution for micropiling:<br />

The system created<br />

great interest among the<br />

650 engineers who attended<br />

this years’ Deep<br />

Foundations Institute exhibition<br />

and seminar, held<br />

in Kansas.<br />

A<br />

tlas <strong>Copco</strong> has introduced a<br />

new production drill rig for<br />

small and medium sized drifts. The<br />

Simba S7 D replaces the well-proven<br />

Simb a 1257 and benefits from a<br />

range of new features.<br />

The new Simba S7 D has an efficient<br />

hydraulic direct control system<br />

for manual control of the drilling<br />

functions, with all controls placed<br />

ergonomically within reach of the<br />

operator’s seat.<br />

The standard version of the rig<br />

includes a canopy with a FOPS approved<br />

cabin available as an option.<br />

The cabin features air conditioning<br />

and a hi-fi sound system as standard<br />

equipment.<br />

Compared to its predecessor, the<br />

Simba S7 D offers higher ground<br />

clearance, a Tier 3/Stage IIIA engine,<br />

increased tramming speed and the<br />

possibility to carry a water hose reel.<br />

Rod handling on the Simba S7 D<br />

is fully mechanized and the rod carousel<br />

can carry up to 10 rods with<br />

one in the rock drill shank adaptor,<br />

allowing mechanized drilling up to<br />

20 metres.<br />

The modular design of the rig<br />

means that it shares many key<br />

components and design elements<br />

with other rigs in the <strong>Atlas</strong> <strong>Copco</strong><br />

range. This simplifies operator familiarization<br />

and makes servicing<br />

simpler while reducing spare parts<br />

inventories.<br />

The Simba S7 D is designed for<br />

a wide range of applications including<br />

long hole drilling, production<br />

drilling and drilling for cable<br />

bolt holes. M&C 3•09<br />

ground engineering micropiling solutions.<br />

“The T111 is the ideal micropiling solution<br />

for a wide range of applications,”<br />

says Bernthaler. “They can be used as<br />

bearing piles for domestic and light industrial<br />

applications, as soil retaining and<br />

reinforcement piles and tension piles below<br />

towers and buoyant structures.”<br />

<strong>Atlas</strong> <strong>Copco</strong> MAI SDA products are<br />

all manufactured according to strict ISO<br />

rules. There are two important quality parameters<br />

for a self drilling system: firstly,<br />

that the rods can withstand the stipulated<br />

working pressure and, secondly, that couplings<br />

and bits can be easily threaded.<br />

Ultimat e load tests are carried out on one<br />

in 200 of the manufactured systems.<br />

The T111 micropile is available in<br />

two dimensions: T111L with an ultimate<br />

tensile load of 2 640 kN (593 k lbf), and<br />

the T111N, with a larger wall thickness,<br />

is rated at 3 650 kN (821 k lbf). M&C 3•09<br />

Easy access: Routine maintenance and servicing<br />

tasks are quickly performed on the Simba<br />

MASTERS<br />

of the art<br />

Unique training programme will<br />

turn rig operators into Drill Masters<br />

Superior productivity in mining and construction operations depends on many<br />

different parameters. Now the most important parameter of all – the skill of<br />

the drill rig operator – is about to be developed into a global standard.<br />

The skill of the drill rig operator is<br />

a key factor in the battle to maximize<br />

productivity and reduce cost.<br />

Now a new training programme has been<br />

launched that will enable the world’s operators<br />

to perform as ‘masters’.<br />

Called Drill Master and recently introduced<br />

by <strong>Atlas</strong> <strong>Copco</strong>, the programme<br />

offers three levels of proficiency –<br />

bronze, silver and gold – with the aim to<br />

enable drillers to achieve optimum performance<br />

and maximum productivity<br />

when using <strong>Atlas</strong> <strong>Copco</strong> equipment.<br />

“This is something our customers<br />

have been waiting for, for some time,”<br />

says Patrik Rylander, leader of the team<br />

behind the programme. “We are proud to<br />

be able to offer such a comprehensive<br />

and modern training programme that<br />

covers all of the skills required to master<br />

our equipment.<br />

“But that’s not all. The skills that the<br />

trainees acquire through this programme<br />

will be recognized around the world,<br />

which means it will be easier for them<br />

to relocate to any country where <strong>Atlas</strong><br />

<strong>Copco</strong> equipment is being used.”<br />

Rylander emphasizes that by enabling<br />

operators to perform at the best of their<br />

ability, employers will find it easier to<br />

achieve their goal of “maximum productivity<br />

at lower cost.”<br />

The programme currently consists of<br />

training in three levels for face drilling<br />

and for surface drilling with SmartRig.<br />

Production drilling will be added to the<br />

programme at a later date.<br />

Influence on productivity<br />

<strong>Atlas</strong> <strong>Copco</strong> is convinced that, irrespective<br />

of whether an operator is “a rookie”<br />

or an experienced driller, the Drill Master<br />

programme will increase their possibility<br />

to have a direct influence on productivity<br />

and cost levels for their companies.<br />

Says Rylander: “It’s all about giving<br />

our customers the possibility to gain,<br />

maintain and increase the skills they need<br />

to succeed under today’s tough conditions<br />

where high productivity is vital and every<br />

second counts.”<br />

Going for Gold: A drill rig simulator is used at the Silver level and<br />

trainees going for Gold are required to repeat what they have learned in<br />

the simulator under real-life conditions at a work site.<br />

Different companies have<br />

different requirements and<br />

the Drill Master programme<br />

is easily adapted to individual<br />

needs. For example, a drilling<br />

contractor may require all of<br />

its operators to achieve the<br />

Bronze level but only its high<br />

potential operators to achieve<br />

the Silver and Gold. Others<br />

may want their operators to<br />

achieve all three levels, which<br />

is particularly interesting for<br />

companies that may be hesitant<br />

about switching to fully<br />

computerized rigs.<br />

Some companies may<br />

even wish to make the programme<br />

mandatory in order<br />

to reduce the risk of damage<br />

caused to equipment through<br />

misuse. Less damage results<br />

in higher productivity, increased<br />

safety and lower<br />

parts consumption.<br />

Drill Master provides a<br />

full set of skills from basic<br />

theory of geology and rock<br />

mechanics at the Bronze<br />

level using e-learning techniques.<br />

The Silver level consists<br />

of a step-by step presentation<br />

followed by hands-on simulator training<br />

consisting of scenarios from real-life<br />

drilling conditions and tasks operators<br />

have to face every day. At the Gold level,<br />

trainees are required to repeat the skills<br />

they have acquired at the Silver level under<br />

real-life conditions at a work site.<br />

The Silver and Gold levels are led by<br />

an <strong>Atlas</strong> <strong>Copco</strong> specialist, ensuring that<br />

the same high quality is maintained irrespective<br />

of where in the world the courses<br />

are held. When the Gold level has<br />

been successfully completed, the operator<br />

qualifies as a Drill Master.<br />

Experience in Spain<br />

One country which has considerable experience<br />

of training drill rig operators is<br />

Spain. Alfonso Gonzalez, Service Supervisor<br />

and Training Co-ordinator at <strong>Atlas</strong><br />

<strong>Copco</strong> in Madrid says: “There has always<br />

been interaction between us and<br />

our customers in the training of their<br />

operator s, but in 2005 we took a big step<br />

forward when we introduced a Boomer<br />

simulator.<br />

“Since then, our customers definitely<br />

realized the benefits of improving the<br />

skill of their operators, both to improve<br />

safety and to keep up their productivity<br />

performance.<br />

“Almost 300 operators have been<br />

trained here over the last four years,<br />

sharing experiences, performing navigation<br />

and drilling exercises in the simulator<br />

in combination with theoretical classes<br />

including safety, daily checks and<br />

drilling protocols.<br />

Powerful drilling combination sets<br />

The GOLD<br />

Turkey’s largest gold mine is securing reliable production using the latest<br />

Secoroc hammers and bits combined with <strong>Atlas</strong> <strong>Copco</strong> surface drilling rigs.<br />

At 157 km 2 , the Kisladag gold mine<br />

in the Usak province of western<br />

Turkey, is the largest gold mine in<br />

the country. It is owned by Tuprag Metal<br />

Madencilik San. Tic. A. (Tuprag), a wholly<br />

owned subsidiary of Eldorado Gold Corp.<br />

Tuprag uses two <strong>Atlas</strong> <strong>Copco</strong> DM45<br />

rigs equipped with Secoroc COP 64 Gold<br />

DTH hammers for bits with a QL60<br />

shank. In addition, there is an <strong>Atlas</strong><br />

Copc o ROC L6 equipped with a Secoroc<br />

COP 34 DTH hammer for bits with COP<br />

34 shanks for presplitting, or a COP 54<br />

Gold DTH hammer for bits with a QL 50<br />

shank for production.<br />

The result is reliable performance on<br />

the site that has continuously increased<br />

production from 70 895 ounces in 2006<br />

to 109 177 ounces in just the first six<br />

months of 2009.<br />

Kisladag started commercial production<br />

in 2006 with a local mine contractor<br />

and has been developed as a low grade,<br />

bulk tonnage open pit operation using<br />

heap leaching for gold recovery.<br />

In May 2008, the mine began the<br />

transition to a being fully owner-operated<br />

pit. The transition, which included<br />

technical and practical training of operators<br />

and maintenance crew, was completed<br />

in four months and the mine began<br />

using its own fleet exclusively in<br />

October, 2008.<br />

Maintaining productivity<br />

Kisladag has been using <strong>Atlas</strong> <strong>Copco</strong><br />

rigs with Secoroc hammers and bits since<br />

the transition began. Penetration rates<br />

are good through the volcanic rock and<br />

Mine Manager, Ahmet Raci Uslu, says<br />

productivity expectations.<br />

STANDARD<br />

the rigs and rock drilling tools were<br />

select ed to maintain the high productivity<br />

rates required at the mine.<br />

“The amount of metres we drill is really<br />

important for us to keep up mine<br />

production,” says Uslu. “In June 2009<br />

we drilled nearly 48 000 metres and we<br />

aim to maintain this level of production.<br />

High productivity is one of the reasons<br />

we chose <strong>Atlas</strong> <strong>Copco</strong>.”<br />

Heavy schedule<br />

The anticipated production capacity at<br />

Kisladag is 1.73 million tonnes a month,<br />

but the current rate of mining is more than<br />

two million tonnes per month. To achieve<br />

this, drilling operations are run for 20 hours<br />

a day; mining operations are 10 hours per<br />

shift and there are 14 shifts per week.<br />

A ROC L6 equipped with its Secoroc<br />

COP 34 DTH hammer averages 45 m per<br />

hour drilling pre-split holes. Hole diameters<br />

are 95 mm and the spacing between<br />

the holes is 1 m. The holes are 22 m deep<br />

and have an inclination of 65–77 degrees.<br />

For production drilling, the ROC L6<br />

with the Secoroc COP 54 Gold hammer<br />

averages 400 m per shift. Each DM45,<br />

equipped with a Secoroc COP 64 Gold<br />

hammer, averages 31–35 m per hour.<br />

The hole diameters are 152–165 mm and<br />

the drilling pattern is 5.5 m x 5.5 m with<br />

vertica l holes. The production drilling<br />

benches are 10 m high with 0.5– 0.8 m of<br />

sub-drilling.<br />

The total drilling capacity for all rigs<br />

is 1 500 –1 700 m per day. Total drill metres<br />

from May to December 2008 were<br />

163 973 m and from January to June in<br />

2009 Kisladag drilled 233 516 m.<br />

Hole quality is checked by measuring<br />

tape before each blast. Kisladag<br />

uses cord, downhole delays and surface<br />

delays for detonators and ANFO and<br />

emulsion ANFO explosives.<br />

While high speed drilling increases the<br />

number of holes completed per day, air<br />

consumption, fuel costs, penetration rates<br />

and bit and hammer life have a major impact<br />

on profitability. The operating life for<br />

the Secoroc DTH hammers with e-kits<br />

is; COP 34 – 9 900 m, COP 54 Gold –<br />

12 853 m, and COP 64 Gold – 27 332 m.<br />

Bit grinding essential<br />

Kisladag uses Secoroc drill bits to<br />

achieve high production rates for extended<br />

intervals. To utilize the full power of<br />

the drill rigs, regular bit grinding is<br />

essenti al. The bit on the COP 34 averages<br />

1 540 m, the bit on the COP 54 hammer,<br />

2 257 m, and the bit on the COP 64<br />

Gold, 3 099 m. However, the economics<br />

of drilling often comes down to balancing<br />

penetration against bit life. A rule of<br />

thumb is that a 10 per cent increase in<br />

penetration rate results in a reduction of<br />

20 per cent in bit life.<br />

To extend the life of its bits and maximize<br />

the number of drilled metres per<br />

bit, Kisladag uses a Secoroc Grind<br />

Mati c grinder, and each bit is reground<br />

pit with 152–165 mm production holes,<br />

152 mm buffer holes and 95 mm pre-split<br />

holes. The purpose of the pre-split holes<br />

and the row of buffer holes is to ensure<br />

New ROC D3 with remote control<br />

<strong>Atlas</strong> <strong>Copco</strong> has introduced two new<br />

drill rigs with built-in remote radio<br />

control systems, the ROC D3 01 RRC and<br />

the ROC D3 03 RRC. The ROC D3 01<br />

RRC features a rod handling system with a<br />

capacity of up to five 3.66 m rods and can<br />

be equipped with R32, T38 and T45 rods.<br />

The onboard <strong>Atlas</strong> <strong>Copco</strong> compressor has<br />

a free air delivery capacity of 95 l/s.<br />

The ROC D3 03 RRC features a long<br />

folding boom with optional rod rack for<br />

manual rod adding and an optional rod<br />

adding system to enable the addition of an<br />

extension rod. The rig can be equipped<br />

with R32 and T38 rods. The onboard <strong>Atlas</strong><br />

<strong>Copco</strong> compressor has a free air delivery<br />

capacity of 80 l/s.<br />

Both rigs are powered by Cummins engines<br />

and offer two rock drills, the 12kW<br />

COP 1240 or 16 kW COP 1640.<br />

“The new ROC D3 RCC rigs not only<br />

enhance drilling performance and productivity,<br />

but also create a safer working environment<br />

in harsher, less stable terrain,” says<br />

Hakan Aytekin, Product Manager at <strong>Atlas</strong><br />

<strong>Copco</strong>.” That’s where you most often rely<br />

on these rigs to perform.” M&C 3•09<br />

ROC T35M a ‘contractor’s dream’<br />

Good performer: Inspecting the wear<br />

on the Secoroc QL60 drill bit.<br />

two or three times. The efficient<br />

grinders extend the service life of<br />

the bits, which also results in less<br />

wear and tear on each rig’s drillstring.<br />

The availability of consumables,<br />

parts and the durability of the equipment<br />

also played a role in Ahmet<br />

Raci’s Uslu’s decision to use <strong>Atlas</strong><br />

<strong>Copco</strong> at Kisladag. “We have our<br />

own maintenance shop and crew. We<br />

get good maintenance support from<br />

<strong>Atlas</strong> <strong>Copco</strong> Turkey and a good supply<br />

of parts and consumables – that<br />

makes life easy for us,” he says.<br />

Since the first year of commercial<br />

production (July 2006), Kislada g<br />

has surpassed productivity expectations.<br />

Initially, plans were to increase<br />

production in year four, but<br />

Tuprag was able to move forward<br />

with expansion in year two.<br />

And the trend continues. Tuprag’s<br />

parent company, Eldorado Gold,<br />

recentl y completed a review of the<br />

Kisladag mine. The study identified<br />

opportunities to effectively increase<br />

annual production by 30–40 percent,<br />

while decreasing unit operating costs<br />

by approximately 15 percent – all of<br />

which is expected to be achieved using<br />

Tuprag’s existing fleet.<br />

For Ahmet Raci Uslu, the relationship<br />

with <strong>Atlas</strong> <strong>Copco</strong> and the<br />

reliability of the equipment will<br />

continue to contribute to the production<br />

capability of Kisladag. And<br />

with Secoroc equipment offering<br />

the lowest cost per metre in the industry,<br />

taking all costs into consideration,<br />

his fleet will also make a<br />

major contribution to the mine’s<br />

profitability. M&C 3•09<br />

Living the dream: ROC T35M in action.<br />

he new ROC T35M for quarrying and<br />

T construction drilling in the 64–102 mm<br />

hole range, is another surface rig that is<br />

expected to quickly become a favourite<br />

choice for contractors. A highly robust rig,<br />

ROC T35M uses the well-proven 18kW<br />

COP 1840 rock drill, giving more drilling<br />

power for less energy input, resulting in<br />

lower fuel consumption.<br />

As Bo-Göran Johansson, Vice President,<br />

Marketing at <strong>Atlas</strong> <strong>Copco</strong>, says:<br />

“Every contractor dreams of higher penetration<br />

rates, straighter holes and better<br />

accessor y life. The ROC T35M employs a<br />

cylinder-driven aluminum feed system<br />

that fulfills this dream by providing optimal<br />

penetration rates and drill steel life.<br />

“Its rod handling system using T38 and<br />

T45 rods, has a streamlined number of<br />

parts ensuring easy adjustment and maintenance,<br />

and the aluminum feed is sturdy<br />

and highly resistant to bending.”<br />

The hydraulic control system, COP<br />

Logic, adjusts the feed speed, feed pressure<br />

and impact pressure in real time,<br />

accord ing to the rock conditions. And continuous<br />

feeding by use of cylinder and<br />

rope, results in constant bit-to-rock contact<br />

and leads to optimum transfer of the<br />

impact power.<br />

In addition, the ROC T35M is built of<br />

modules and parts that are common to<br />

Atla s <strong>Copco</strong>’s surface crawlers. This makes<br />

training easy and reduces parts stocking<br />

requirements for contractors with different<br />

<strong>Atlas</strong> <strong>Copco</strong> rig models.<br />

Maintenance is simplified thanks to<br />

all-around access to service points and<br />

good hose management. Together with<br />

ROC Care and COP Care service agreements,<br />

this means fewer breakdowns,<br />

increased availability and lower service<br />

costs. M&C 3•09
