deep mine
Subterranean ore extraction
A deep mine is a mine that extends far underground, as opposed to surface mining operations like open pits or strip mines.
Deep mines use vertical shafts or sloping tunnels to reach deposits of coal, gold, or other minerals buried hundreds or thousands of feet below the surface: The deep mines of South Africa reach nearly two and a half miles down.
