What Is Subsurface Mining? | Reference

Subsurface mining is the removal of deposits from the earth by drilling underneath layers of rock and dirt. These deposits are difficult to reach from the surface and require the drilling of vertical or horizontal shafts for access. The shafts are reinforced with supports before workers access the tunnels.Surface mining - Wikipedia,Surface mining is subject to state and federal reclamation requirements, but adequacy of the requirements is a constant source of contention. Unless reclaimed, surface mining can leave behind large areas of infertile waste rock, as 70% of material excavated is waste.Here are the Types of Underground Mining and Their,,Depending on how these ores are extracted, mining methods can be categorized as 'surface' or 'underground' types. In surface mining, the rock barrier on top of the deposit is removed to access the ore. However, sometimes, such deposits occur too far below to access them from the surface.
