We engineer an extensive range of underground drill rigs for mining development and production. Available in a variety of feed lengths, boom configurations and size classes, our underground drill rigs maximize productivity while delivering the lowest cost per meter.
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice, typically 0.6–1.0 meters thick. The longwall panel (the block of coal that is being mined) is typically 3–4 km long and 250–400 meters wide.
Designed as a 3Mt/y operation, Fording River began production in 1971 and made its first shipment of metallurgical coal in April 1972. Formerly Fording Coal Ltd's largest metallurgical/thermal coal mine, its primary product is high-quality metallurgical coal used to produce coke for the international steel industry.
