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.

Generally this system is best suited for deeper mines that will require higher production rates. A general rule of thumb states that a mine that has the potential to go deeper than 500m or plans to have production rates over 400000t/year will be best suited to a shaft . Shaft access can also be utilized through an internal shaft, or a winze.
Conventional mine shaft sinking methods involve the performance of a cycle of different operations—drilling and blasting, removal of smoke and cleaning of flyrock 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 ...
