Underground mining methods: These are the methods/techniques employed when the depth of the deposit,the stripping ratio of the overburden to ore,or both becomes excessive to surface exploitation. Choice of an underground mining method is often closely related to the Geology of the deposit and degree of ground support necessary to make the method productive and safe.

Mary McMahon Entrance to a coal mine. Underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. This is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ...

Underground mining In underground mining, a minimal amount of overburden is removed to gain access to the ore deposit. Access to this ore deposit is gained by tunnels or shafts. Tunnels or shafts lead to a more horizontal network of underground tunnels that directly access the ore. In an underground mining method called 'stoping' or ...

Mine subsidence can be defined as movement of the ground surface as a result of readjustments of the overburden due to collapse or failure of underground mine workings. Surface subsidence features usually take the form of either continuous or discontinuous. Mine subsidence subsidence usually occurs gradually when it is concurrent with mining.
