Surface mining is accomplished through two general approaches: area mining and contour mining. Area mining involves a broad region where the mineral is relatively near the surface and the terrain is not steep. Mining involves the creation of a long series of parallel pits, which are then reclaimed even as the active mine proceeds in one direction.
