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.
Before the development of suitable conveyor belts, coal was transported from the mine by rail transport systems, but today coal transport is almost invariably by conveyor belts. In a mine with drift or adit access, the conveyor transport can be all the way to surface but in a mine with only shaft access winding or hoisting of coal in the shaft ...
This conveyor, with return run traveling parallel but opposite in direction to the outgoing or coal haulage run, permits not only haulage of coal from faces, but simultaneously permits transportation of men and supplies into the mine at any time, see Figs. 1 and 2.
