Coal mining

In a continuous operation, one machine—the continuous miner—rips coal from the face and loads it directly into a hauling unit. In both methods, the exposed roof is supported after loading, usually by rock bolts. Under favourable conditions, between 30 and 50 percent of the coal in an area can be recovered during development of the pillars.
