The essential geomechanical features of longwall and caving methods of mining were outlined in Chapter 12. Longwall and caving methods are distinguished from other mining methods by the fact that the near-field rock undergoes large displacements so that mined voids become self-filling. In caving methods, the far-field rock may also undergo ...

Longwall Mining Overview Introduction underground COAL

LONGWALL MINING Overview. In the method of secondary extraction known as longwall mining a relatively long mining face (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block, with one rib of this new roadway forming the longwall face.

What is Longwall mining and how efficient it is to extract coal

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 ...
