Glossary of Mining Terms

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.

Vibrating Feeder Design

The fast efficient, high-tonnage method of reclaiming coal from concrete storage silos is to use a series of feeders to extract uniformly across the entire bottom of the silo. For example, a 70 ft. diameter silo would use seven feeders located beneath 10 ft. square openings, three directly over a belt and two on either side, to provide mass-flow unloading while minimizing segregation problems.
