Answer 2

Correct answer: True

Subsurface mining is one of the types of mining, which is done when minerals that are mined are present below the surface of the earth. This is done because the minerals cannot be obtained from the surface level. Then, in that case, subsurface mining is done.

It is done by constructing a reinforced tunnel down the surface to the place where the mineral resource is present.
