Room & Pillar Mining: Safe, Efficient & Environmentally Friendly
Working 300-450 feet underground, miners use 6-foot, fully grouted metal bolts inserted every 4 feet to support the ceiling. To keep fresh air flowing at all times, the mine is fully ventilated. Advanced mining equipment, like a continuous miner, is used to safely and efficiently remove coal.
Typically, a crew of 4 is working underground. They enter the mine on a man-trip — a specially-designed, low-profile mining vehicle — through a 2,400-foot, 16% grade tunnel. It takes 20 minutes to arrive at 1 of the 5 working sections. To speed up the delivery of support crew and supplies, a portal has been installed in the north end of the mine.
