Surface Mining | Encyclopedia

Operations begin near the coal outcrop — the point where the ore lies closest to the surface. Large stripping shovels or draglines dig long parallel trenches; this removes the overburden, leaving the ore exposed. The overburden excavated from the trench is thrown into the previous trench, from which coal has already been extracted.
