CarboPur LT<br />
Advanced resin injection technology<br />
for mining<br />
CarboPur LT is<br />
a major new<br />
advance in resin<br />
injection technology<br />
for mining<br />
applications<br />
where chemical<br />
reaction<br />
temperature is<br />
a concern for<br />
safety.<br />
Major features<br />
Low reaction temperature - safe to use in coal seams<br />
Controlled expansion - better yield + crack penetration<br />
Does not react with water in strata - no uncontrolled<br />
foam expansion<br />
High bonding <strong>and</strong> adhesive strength - improved consolidation<br />
properties<br />
Applied at 1:1 ratio - can use st<strong>and</strong>ard pump system<br />
<strong>New</strong> safe development<br />
<strong>Resin</strong> injection from <strong>Minova</strong> is a proven system for the<br />
consolidation of coal long wall face <strong>and</strong> ‘T’ junctions in<br />
modern mines with the benefits of increasing productivity<br />
<strong>and</strong> improving safety. Some coal seams are known to be<br />
prone to spontaneous combustion <strong>and</strong> in such cases the<br />
choice of injection resin system is crucial to maintain safety<br />
<strong>and</strong> prevent any chance of localised heating. For such difficult<br />
conditions <strong>Minova</strong> has developed a new resin,<br />
CarboPur LT, which offers all the high performance required<br />
of an injection resin but with a much lower <strong>and</strong><br />
controlled reaction temperature.<br />
Controlled foaming <strong>and</strong> expansion<br />
CarboPur LT can be formulated to give a foam factor from<br />
1 to 20 times expansion <strong>and</strong> so can be adjusted to suit individual<br />
customers requirements. Another major feature is<br />
that CarboPur LT is not effected by any water in the strata<br />
<strong>and</strong> so the expansion or foaming factor is not affected <strong>and</strong><br />
remains constant. This is important when uncontrolled<br />
resin expansion might cause collapse of the coal face.<br />
Simple application<br />
To make application easy the ratio of CarboPur LT has<br />
been maintained at 1:1 so that st<strong>and</strong>ard <strong>Minova</strong> injection<br />
pumps <strong>and</strong> equipment can still be used with this new<br />
technology. St<strong>and</strong>ard packers <strong>and</strong> injection accessories are<br />
used <strong>and</strong> the application process is the same as with any<br />
product in the <strong>Minova</strong> injection chemical range.<br />
Carbomine<br />
Ultra safe injection resin<br />
Carbomine, a phenolic injection resin, was first developed<br />
for the Australian coal market to stabilise underground<br />
rock formations. The resin is fully LOBA compliant <strong>and</strong><br />
meets strict safety <strong>and</strong> environmental st<strong>and</strong>ards.<br />
Carbomine has low viscosity to penetrate the fines cracks,<br />
low exothermic temperature <strong>and</strong> high bond strength to<br />
ensure geological stability. The two component system is<br />
mixed at a 4:1 ratio, which makes it ideal in combination<br />
with <strong>Minova</strong>’s cavity fill product, Carbofill, as the same<br />
pumping equipment can be used. The dual use of the<br />
same application pump ensures substantial time saving<br />
in set up for applications where both products are found<br />
advantageous to meet safety <strong>and</strong> production requirement.<br />
Carbomine has a very low exothermic temperature of less<br />
than 60 °C <strong>and</strong> during in underground field trials, neither<br />
phenol nor formaldehyde was detected. The excellent<br />
strata penetration <strong>and</strong> superior bond strength characteristics<br />
make Carbomine an ideal choice for underground<br />
application.<br />
Carbomine has recently had a very successful Australian<br />
underground application at Donaldson Coal’s Tasman Mine<br />
near <strong>New</strong>castle. Carbomine was injected into a rib line<br />
as a precautionary sealing measure to prevent spontaneous<br />
combustion after air passages through the coal pillar<br />
had found elevated heat. The application was successfully<br />
completed by experienced personnel from <strong>Minova</strong>’s NSW<br />
Operations <strong>and</strong> Technology teams.<br />
Advantages<br />
Low viscosity<br />
Low exothermic temperature<br />
High bond strength<br />
Compatible with other <strong>Minova</strong> systems
Tekcrib<br />
Supplementary Roof Support System<br />
The Tekcrib roof support system is designed as a viable al-<br />
ternative to conventional supplementary roof support in<br />
mine roadways <strong>and</strong> working zones. It is based upon <strong>Minova</strong>’s<br />
long experience with pump packing support products.<br />
Tekcrib is a non-combustible, simple <strong>and</strong> innovative roof<br />
support system using minimal installation time. Cylindrical<br />
grout containment bags (Ø 600 mm, 760 mm, or size to<br />
suit conditions) are secured to the mine roof <strong>and</strong> subsequently<br />
filled with Tekcrib foamed cementitious grout.<br />
A specially designed Tekplacer grout pump combines the<br />
Tekcrib pow-der with air <strong>and</strong> water at the correct ratios<br />
to produce the cementitious foam. The foam is typically<br />
pumped a distance of 300 m but much longer distances are<br />
possible. The mix begins to gel within minutes of entering<br />
the containment bag <strong>and</strong> cures to a final strength, typically<br />
from 3 - 6 MPa depending on site requirements.<br />
Advantages<br />
Safety – less exposure time in questionable situations/<br />
areas<br />
Ease of Use – ideal for difficult-to-reach areas<br />
Variable Strength – compressive strength 3 – 6 MPa<br />
Simple<br />
Full Surface Contact – conforms to irregularities on the<br />
roof <strong>and</strong> floor so not affected by point loading forces<br />
Fast Installation Speed – average installation rate of<br />
roughly 15 cribs per hour (600 mm dia. x 2 m height)<br />
High Strength – typical peak strength is 135 tons with<br />
similar residual strength; good yield typically at least<br />
400 mm of convergence is achieved<br />
Terraliner BH<br />

Blasthole lining for improved mining<br />
or tunnelling efficiency<br />
Terraliner is a unique system which can be applied as a<br />
liner to stabilise blastholes. The liner forms a semi-rigid<br />
coating which follows the shape of the blasthole adapting<br />
it’s imperfect shape. The product is applied using a specific<br />
spray application system suitable for upholes <strong>and</strong> downholes<br />
in underground <strong>and</strong> surface mining applications.<br />
Maintaining the integrity of blastholes is an important<br />
factor in efficient mining operations. Blastholes may<br />
become blocked from movements in ground or rock fragments<br />
loosening from nearby blasting activities. Premature<br />
closure of blastholes means additional costs <strong>and</strong> delays are<br />
incurred in redrilling or blast performance is compromised<br />
with associated downstream cost impacts.<br />
Terraliner is compatible with typical blasting agents used<br />
in the mining, tunnelling <strong>and</strong> construction industries. It<br />
has negligible impact on blast performance <strong>and</strong> is applied<br />
to dry <strong>and</strong> de-watered holes.<br />
Advantages<br />
The blasthole can be filled up to 6 months after drilling<br />
has been completed<br />
The membrane will protect the hole from intrusion of<br />
water<br />
Blasthole drilling programs can be executed seperately<br />
to blasting sequences<br />
Productivity <strong>and</strong> safety are improved<br />

Application in tunnelling (small picture) <strong>and</strong> mining<br />
Tekflex DS<br />
Innovative coating systems<br />
TEKFLEX DS is a thin sprayed liner used for stabilisation<br />
as well as sealing in tunnelling or underground mine<br />
workings. The polymer based liner features excellent<br />
properties regarding strength <strong>and</strong> flexibility. It increases<br />
the load capacity of the rock <strong>and</strong> forms a persistent<br />
membrane. The powder consists of mineral additives <strong>and</strong><br />
co-polymers <strong>and</strong> is mixed just with water prior to application.<br />
Recommended applications in Tunnelling<br />
Sealing of new shotcrete layers<br />
Sealing of pre-cast tunnel segments<br />
Stabilisation of tunnel portals <strong>and</strong> entries<br />
Recommended applications in Mining<br />
Drift sealing against gas <strong>and</strong> water ingress<br />
Sealing of a drift prior to grout injection<br />
Stabilisation of face <strong>and</strong> roof for securing against rock<br />
<strong>and</strong> coal slides during driving, <strong>and</strong> general maintenance<br />
<strong>and</strong> repair works<br />
Temporary face <strong>and</strong> roof stabilisation against rock <strong>and</strong><br />
coal slides at longwall/drift transition<br />
Securing of rock surface against alteration<br />
Before starting the<br />
application the surface<br />
to be sprayed on<br />
should be thoroughly<br />
cleaned to remove<br />
any dust <strong>and</strong> loose<br />
particles.<br />
TEKFLEX DS can be<br />
applied on dry as<br />
well as on humid<br />
surfaces, but any<br />
Advantages of Tekflex DS<br />
Dry spraying process<br />
Application with st<strong>and</strong>ard pumps<br />
Application on humid <strong>and</strong> dry<br />
surfaces<br />
Material gels within seconds<br />
Elongation at break > 10%<br />
Approved for the German coal<br />
mining<br />
flowing water should be sealed off before spraying.<br />
TEKFLEX DS can be applied with a pump typically used in<br />
tunnelling or mining to spray materials according to the<br />
dry process.<br />
During the spray process the powder is mixed with water<br />
in a specialised nozzle. A suspension, which coagulates<br />
within seconds, is formed building up a continuous membrane<br />
on the sprayed surface.<br />
This membrane is tangible after a few minutes <strong>and</strong> its<br />
stability increases over the next few days resulting in a<br />
compact but elastic coating adhering on most surfaces.<br />

Long Distance Pumping Technology<br />
<strong>Minova</strong>’s long distance pumping means a change in the<br />
way the miner works. Instead of small pumps or cans<br />
which constantly have to be supplied a long distance<br />
pump can be placed in the mine.<br />
In general, long distance pumps are today installed<br />
centrally in the coalmine in order to supply entire mining<br />
fields from one location. If this is not reasonable, then the<br />
injection unit CT-PM is installed in the main or tailgate<br />
road of the coal face. The coal face is supplied by means of<br />
tubes <strong>and</strong>/or hose lines.<br />
Long distance pump CT-PM<br />
The pump can convey distances up to 5,000 meter <strong>and</strong> it is<br />
remotely operable. It is also electrically driven with radial<br />
piston technology <strong>and</strong> allows for an adjustable flow rate<br />
without pulsation.<br />
The customer can choose between 2,000 or 600 liters resin<br />
containers depending on the expected injection requirement<br />
for the injection shift.<br />
2000 liters storage tank for A (white) <strong>and</strong> B (black) component<br />
The long distance pumping system consists of 3 components:<br />
Long distance pump e.g. CT-PM<br />
Storage tank for each component serving as a reserve<br />
<strong>and</strong> supply tank for the pump<br />
Reusable containers<br />
600 liters storage tank for B (black) component<br />
Introducing long distance pumping allows for an immediate<br />
initiation of measures for rock stabilization as the<br />
injection resin is available constantly.<br />
The integration of this comfortable <strong>and</strong> efficient injection<br />
technology increases the value to the customer. It also increases<br />
productivity, secures production, reduces accidents<br />
due to falling rocks <strong>and</strong> reduces costs in transport, labor<br />
<strong>and</strong> maintenance. The implementation of long distance<br />
pumping improves safety <strong>and</strong> productivity in the mine.<br />
Benefits of long distance pumping technology<br />
<strong>Inc</strong>rease <strong>and</strong> backup of the production by means of<br />
permanent availability of the injection resin with a<br />
high st<strong>and</strong>ard of quality<br />
Injection option during the extraction<br />
Reduction of transport costs<br />
Reduction of maintenance costs<br />
Reduction of personnel requirements<br />
Improvement of ergonomics <strong>and</strong> occupational safety
