The technical literature is replete with descriptions of and data on shaft sinking equipment, methods and costs. The subject of shaft sinking has been discussed at some length in an earlier Bureau of Mines bulletin. A number of shaftsinking operations are described in detail in the series of information circulars on mining methods and costs, to some of which reference will be made later.
Shaft mining or shaft sinking is excavating a vertical or nearvertical 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.

mining of the diminishing Merensky reef, and to increase the life of mine of the Townlands Shaft. Through the 3 raisebore holes of 3, 8 metres diameter respectively, with the above mentioned refridgeration plant, an additional air supply of 600 m3/s will be supplied for the deepened zone, cooling the air down to the calculated 18 degrees Celcius.
For deeper shafts the minimum shaft size increases to accommodate larger shaft sinking equipment and allow a greater airflow for ventilation purposes. Circular shafts. The most commonly used shaft design in modern day mining is of circular or elliptical shape. In moderate to high production, larger working areas are necessary to provide ...
In today''s technologicallyadvanced society, mining techniques are always improving. For example, using surface mining techniques, many mining operations are now able to extract over 85 percent of minerals and 98 percent of metallic ores — without digging a shaft or endangering the lives of workers.
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.

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...
Oct 28, 2019· 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.
