DESIGN OF MINE SHAFT ELEVATOR

When it comes to design of a mine shaft, there are two options: circular shafts and horizontal shafts (Figure 1, Figure 2). Circular shaft is the most commonly used one. If the shaft should be deep and shaft diameter is supposed to be more than 4.5 meters, circular shafts …

Segmental Shaft Sinking | Services - Donegan Civil Engineering

Caisson Shaft Sinking. Jacked caissons can be constructed from 2.40m to 25.00m diameter. The company has the expertise to construct shafts in all types of ground conditions. Caisson shaft sinking is the preferred method generally for smaller diameter shafts, especially in poor ground conditions, such as saturated sands and gravels.

Shaft construction - QueensMineDesignWiki

The shaft size is dictated by the minimum size to contain all needed conveyances and cages as well as guides to maintain alignment. Provisions for ventilation, mine services, and sometimes a man way must also be taken into consideration. For deeper shafts the minimum shaft size increases to accommodate larger shaft sinking equipment and allow a ...

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 ...

Mine Shaft Sinking Methods

Conventional mine shaft sinking methods involve the performance of a cycle of different operations—drilling and blasting, removal of smoke and cleaning of fly-rock lodged on overhead timbers, mucking and hoisting of the broken rock, and timbering. The latter (a) may be the last operation of the cycle, (b) may be carried on during drilling and mucking, provided it is done from a substantial ...
