How was coal extracted from the earth?
Coal is extracted in two methods. One is by digging tunnels into the earth and following the vein of coal, removing it by rail cart. The other is strip mining where they remove the earth above the coal and dig down to it. This way usually involves the removal of entire mountain tops to get at the coal.

Depends on what the mineral is, and where it is located.
