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. The mining process involves the use of a large cutting machine, the longwall shearer, which ...
