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 Mining Industry Gas Detection Systems Equipment CONSPEC has been serving the mining industry with MSHA products since 1978 and is a leader in the field of gas detection Our gas detection equipment is "coal grade" - built for reliability in the harshest of environments
