Longwall mining is a highly productive underground coal mining technique.Longwall mining machines consist of multiple coal shearers mounted on a series of selfadvancing hydraulic ceiling supports.The entire process is mechanized.Longwall mining machines are about 800 feet 240 meters in width and 5 to 10 feet 1.5 to 3 meters tall.
Coal mining coal mining underground mining in underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata.Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities.
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.
