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 ...
