Subsurface mining (deep mining) employs underground tunnels to access deeper deposits (figure (PageIndex{c})). Some underground mines are thousands of feet deep, and extend for miles. Miners ride elevators down deep mine shafts and travel on small trains in long tunnels to get to the coal. The miners use large machines that dig out the coal.

Shaft mining is an excavation method used to access an underground ore body from the top down. The term "shaft" refers to the vertical tunnels sunk underground for mining and engineering projects.. When the opening starts on the surface, the resulting tunnel is called a shaft. If the vertical tunnel starts underground and pushes upward, it's called a sub-shaft.
The production from No. 4 Shaft and No. 5 Shaft is conveyed underground to No. 2 Shaft on 22 and 24 levels for hoisting.
