Strip mining is a form of surface coal mining where overburden is removed to expose the underlying coal seam. There are three general types area mining on flat terrain and contour and mountain top removal mining on steep terrain. Area mining is practiced on relatively flat terrain such as mines found in the mid-west and far western coal fields.

Andrew P. Schissler, in Encyclopedia of Energy, 2004 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.
