Mining Techniques Geology for Investors

2013-6-14  Mining techniques can be divided into two broad categories: surface mining and subsurface mining (See Figure 1). Surface mining consists of stripping soil and vegetation away and possibly a limited amount of rock and then removing ore in large quantities. Conversely, subsurface mining involves sinking a mineshaft and digging tunnels to reach a ...

2021-7-15  Strip mining, like other types of surface mining, finishes in hurting the area around the mine. The rock, gravel, trees, plants, and filth are dumped in regions round the mine. When it rains, this runs over the land and into watercourse and rivers.

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.
