Abutment In gold mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid gold 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 gold ahead of the face and the back
