Coal mining - Wikipedia

Shortwall mining, a method currently accounting for less than 1 percent of deep coal production, involves the use of a continuous mining machine with movable roof supports, similar to longwall. The continuous miner shears coal panels 150 to 200 feet 45 to 60 metres wide and more than a half-mile 1 km long, having regard to factors such as geological strata.
