Mine hoisting systems - QueensMineDesignWiki
Friction hoists or Koepe hoists are the second main type of hoist. Instead of a drum located some distance away for the shaft, as in drum hoisting, the drum is directly above the shaft itself. Rope passes over the wheel during hoisting operations. This type of hoist is synonymous with low initial capital cost and high reliability. In operations that use this type of hoist rope guides are often used. The low …

Shaft mining - 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 is …
