oads to nowhere: Summer aerial viewsof portages, such as this one, look like roadscut randomly across deserted islandsEasy does it: A curve on approach to aportage helps redirect the under-ice waveput into play to keep the laneways smoothand snow-free. Snow piling up on the iceroad can be a real hazard, compromising icethickness and strength. Many of Nuna’s offhighwayplow trucks are likewise poweredwith Cat engines.<strong>Meet</strong> Tony Mecir, <strong>Finning</strong>’s mining accountmanager, whose job it is to look afterthe provision and maintenance of Cat equipmentfor De Beers and Tahera mine sites andNuna Logistics. When ice road constructionswings into high-gear in mid-January, Meciris on his toes to ensure the 150-person crew,stationed at three camps along the route, isequipped with fully-functioning machinery.If something breaks down, Mecir must dispatcheither a repair crew or, in the worst-casescenario, break down a 100,000-pound Cat toready it for Hercules aircraft transport.“The biggest challenge is having the machinesshipped to very, very remote locationswhere you have no access roads and you havetight time constraints,” Mecir says. “So you’rebasically at the mercy of the airlines, the peoplewho have the Hercs.” And preparing forsuch a dispatch is no small task. One or twomechanics are required to disassemble amachine in Edmonton for transport and asimilar amount of time and man-power isnecessary on the receiving end to put it backtogether again.“When the ice road is not there, it’s theonly way to get this equipment to site,”added Mecir. “It’s not uncommon to spend$50,000 to $100,000 to get a machine intosite, depending on where it’s going.”Breakdowns can range from the mundaneto the unbelievable as frigid temperatures occasionallydip down to -70°C, testing the resolveof the heaviest iron.“You will see raw steel break and crack,grader blades will break, motor grader drawbars will crack and break in half,” says Mecir.No matter the temperature, Mecir and the<strong>Finning</strong> techs <strong>service</strong> the equipment.Road building commences from threecamps along the route – Dome Lake, LockhartLake and Lac de Gras – simultaneously.According to Zigarlick, if construction weredone in an end-to-end fashion, it would be72 tracks & treads • Spring 2008 www.finning.ca
impossible to complete the job on schedule.Weather permitting, the road reaches optimalthickness of approximately 107 centimetresabout five weeks into construction,opening up the lifeline for the heaviest grossvehicle weights, as much as 194,000 pounds,to be dispatched.There’s a stream of big rigs heading to andfrom the mine sites that includes road maintenancecrews plowing snow from two lanes(a primary inbound one and a secondaryreturn express lane for empty rigs) and a securityteam monitoring traffic and speeds. Activityon the Tibbitt-to-Contwoyto ice-way isa delicate ballet of not-so-delicate machinery.Inbound rigs are released from Yellowknifefour at a time every 20 minutes and must stay500 metres apart and travel at speeds between25 km/hr to 50 km/hr.“There are certain parts where the speedwould be lower depending on the depth ofthe lake and thickness of the ice,” says Nuna’sAlan Fitzgerald, senior superintendent forthe winter road. “Certainly, controlling truckspeed is a critical factor in order to maintainthe ice integrity.”Moving any faster can cause the ice toblow apart. Moving vehicles cause a wave toform on the underside of the ice, in front ofthe wheels. Ice breaks can occur if the truckovertakes the wave moving underneath, or ifthe wave hits the land portage and is deflectedback into the unfrozen lake water under theice with too much force.Despite the inherent risks, played up inthe History Channel’s popular television seriesIce Road Truckers, the safety record of theice road is solid. Since the road’s beginning,one person has died – succumbing to heartfailure after hitting the freezing water whenhe plunged through the ice in 1983.“I was a little browned off about that televisionseries,” says Zigarlick of the HistoryChannel’s treatment of what has been a historicallysafe construction venture. Since theseries aired, the joint venture partnership hasopted out of participating in future episodes.The partnership between Echo Bay MinesLtd., BHP Billiton, and Diavik DiamondMines Inc. recently lost a fourth member. Inmid-January, Tahera, owner of the Jerichomine, filed for bankruptcy protection citinginsufficient funds to continue its operations.“It’s a very small percentage player inthe road,” says Erik Madsen, Nuna’s directorof winter road operations for the joint venture.Last season, he says, Jericho accountedfor just 500 of the 11,000-plus loads. “Mostlikely we’ll stop the road at Lac de Gras thisyear, making it 180 kilometres shorter than inprevious seasons.”Madsen was unwilling to disclose thecost of the ice road but would say the financialburden is shared by members of thejoint venture based on total tonnage dividedby the amount of loads and distancetravelled. Other businesses, not part of theventure, are charged on a cost-per-ton/kilometre schedule. Last season, a total of330,000 tons were transported and as ofthe start of the 2008 season, Madsen expectstruckers to deliver 300,000 tons ofequipment and supplies; among the cargoare <strong>Finning</strong>’s Caterpillar machines – crucialto sustaining the NWT’s burgeoning miningsector.Of ice and diamondsThe Tibbitt-to-Contwoyto Winter Road serves <strong>Canada</strong>’s northern diamond mines.nunavutnorthwest territoriesEkati Diamond Mine, BHP Billiton:Since opening for production in1998, this open pit mine hasproduced over $1 billionin rough diamonds andemploys 850 people.
