  • What is Shaft Mining? (with picture)

    Mining is a physically draining profession. Shaft mining—also referred to as shaft sinking—is a type of mining process used to vertically gain access to an underground mining facility. There are many different components which make up the shaft, all of which play a very important role in the mining process.

    OverviewParts of a mine shaftShaft liningShaft compartmentsSee alsoExternal links

    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 is underground, it is called a winze or a sub-shaft.
