Mining Underground mining Britannica

Mining 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

Underground Mining Mineral Production Activities

Mining Production Activities. 11. What is underground mining? Mineral deposits which cannot be economically extracted by surface mining techniques may be mined by underground methods. Underground (U/G) mining can be applied to orebodies of any description, from tabular to massive and pipes, from relatively shallow depth to ultra-deep.

Underground Mining Methods — New Pacific Metals

Block caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.
