Shaft Mining, Mining Techniques, Underground Mining,

Shaft Mining. Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world.Shaft sinking - Wikipedia,Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining projects. When the top of the excavation is the ground surface, it is referred to as a shaft; when the top of the excavation isShaft Communication | SpringerLink,Bandyopadhyay LK, Chaulya SK and Kumar S (2002) A proposed wireless communication system for underground mines.

Tunnels have many uses: for mining ores, for transportation—including road vehicles, trains, subways, and canals—and for conducting water and sewage. Underground chambers, often associated with a complex of connecting tunnels and shafts, increasingly are being used for such,Evander Mines – underground The 8 Shaft pillar is expected,,during June 2020. Mining of the 8 Shaft pillar significantly reduces the risk profile of Evander Mines’ underground operations, with simplified logistics, modern underground mining support and reduced travelling times to the workplace expected to contribute to improved production costs.
