Strip Mining

Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling. In contour or area stripping, the overburden is hauled with different equipment than what digs or removes the overburden. In strip mining, the overburden is mined and moved by the same equipment: draglines or continuous excavators.
