Subsurface Mining Definition
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.

Answer and Explanation: Subsurface mining is when the materials being mined are below the surface of the Earth. This means that the mining must occur below the surface as well, because the resources cannot be accessed from surface level. Subsurface mining is done by building reinforced tunnels down from the surface to the place where the resource is located.
