Mining Underground mining When any ore body lies a considerable distance below the surface the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive and underground techniques must be considered. Counting against underground mining are the costs which for each ton of material mined are much higher underground than on the surface.
