    Apr 16, 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.
