Mining - Underground mining Britannica
Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the
Underground Mining Transportation Systems
Skips are shaft conveyors for hoisting ore/coal or waste from the underground. The most significant feature is the method by which ore/coal is discharg ed from the skip. Skips now in use are almost always the bottom-dump design. Skip loading is often automated in conjunction with automated slumping and automated ore/coal hoisting systems.

Glossary of Mining Terms - Coal Education
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.
