PHASES OF A MINING PROJECT
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 ...

What is Underground Mining? (with pictures)
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 ...

Coal Exploration and Mining
two basic methods of extracting coal, surface mining and underground mining, are introduced. Firstly, two main methods—strip mining and openpit mining—of surface mining are discussed. In underground mining, room and pillar, shortwall, and longwall mining methods are introduced. Finally, a brief prospect for coal exploration and mining

The Actual Difference Between Surface and Underground Mining
Openpit Mining: Removing ore to leave a crater. Quarrying: An openpit mine for construction materials. Strip Mining: Ore is removed in parallel strips. Mountaintop Removal: Top of a mountain is blasted to remove deep ore. Dredging: Ore is removed from a river bottom. The main methods of underground mining are: Room and Pillar Mining: Removing ore, while leaving behind some for roof support.

MINE SUBSIDENCERev 1 | Mining | Fault (Geology)
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.
