Underground Mining Mining And Geomorphology

Longwall mining is a method of underground mining, usually used in coal mining. The method is fairly basic. A tunnel is created by basically cutting back the coal with a rotating drum and shearers. The coal fragments are then conveyed up to the surface. A series of hydraulic jacks (aka., chocks, are used to support the cavity wall, temporarily).
