In situ mining (see mining solution page) can be more environmentally friendly than underground mining and is cheaper than many mining methods (UlmerScholle, 2008). However, in situ mining cannot be implemented in all cases as the ore needs to be beneath the water table (the level at which the ground is saturated with water) and it needs to be porous enough to let the leaching solution ...

Strip Mining

Andrew P. Schissler, in Encyclopedia of Energy, 2004 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.
