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 for such essential activities ...
Longwall machines sheer coal from the face in a circular motion. The broken coal falls into a pan line, which leads to a conveyor belt and then to the processing plant. Longwall machines now extract more than 55 percent of all West ia coal mined underground. Continuous miners are used primarily in room-and-pillar mines and operate ...

pit machinery can also be used for other purposes such as civil construction, whereas underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/da y and almost 365 days/year in order to use open pit machinery for as many hours as possible, thereby reducing the number of machines required.

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
