Strip mining gets its name from the fact that the process involves stripping the surface away from the mineral that's being excavated (usually coal). Soil, rock, and vegetation over the mineral seam is removed with huge machines, including bucket-wheel excavators. This type of mining makes sense when the mineral is near the surface.
