What Is Subsurface Mining? Reference

16/04/2020· 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. Advertisement. How the subsurface minerals are mined depends upon the type and depth of

Subsurface Exploration SpringerLink

Ground investigation usually begins with the use of nonintrusive methods, usually ground surface geophysics, or less commonly airborne methods, allowing a general insight to subsurface conditions. Geophysical exploration aims to gather information about the subsurface over a large area at an acceptable cost. The resulting information helps to exclude unsuitable sites, but the most important
