Glossary of Mining Terms

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 facecrushing value of coal - everykcoin crushing value of coal mobile crusher plant of coal vibrating sieve separatorCoal crusher machine coal grinding mill plantmobile coal SBM design coal processing.
