Luscar Mine

"The Luscar Mine is a metallurgical coal mine located in the foothills of the Canadian Rockies, 41 km southeast of Hinton, Alberta. The mine is operated by Cardinal River Coals Ltd., a 50/50 joint venture between Luscar Ltd. and Consolidation Coal Company of Canada. The mine produces a high quality medium volatile metallurgical coal which is sold on the export market principally to Japan and South Korea. Operations consist of a surface mine with capacity to produce 3.0 million tonnes per year and an underground mine which is currently mothballed due to market conditions.GeologyBedrock units within the Luscar minesite are of Devonian to Upper Cretaceous age. The commercial coal measures in the area are, however, confined within the Lower Luscar Formation. The Luscar Formation consists of a 460-metre thick sequence of interbedded sandstones, shales and coal seams. The sequence is primarily deltaic in origin, and is bounded to the north and south at the Luscar mine by tectonically induced thrust faulting.The only mineable coal seam at Luscar is referred to locally as the Jewel seam. Average thickness of this coal measure is usually 10.5 m to 14 m, although in some areas folding and faulting has produced ""pods"" of coal from 15 m to over 40 m thick while in others the structural deformation has thinned the coal to 3.0 m to 4.6 m. Waste within the Jewel seam seldom exceeds a metre of shale, carbonaceous shale or infrequent sandstone stringers.Reserves and Coal QualityProven surface mineable reserves, based on pit scheduling through 1996, are 50.8 million raw tonnes. An additional 19.2 million raw tonnes are contained in possible extensions to the present planned operations. These surface mineable reserves are considered to be those reserves within 155 m of the surface. Underground reserves, located within 770 m of the surface show that 25.7 million raw tonnes have been proven to date in additon to 27 .5 million indicated and 260 miIJion inferred.Coal specification at Luscar Mine is as follows:"
