CHINA MINE ENGINEERING

This paper analyzes the main problems existing in the deep shaft mining of a gold mine in South Africa. Combined with Phase II project under implementation, the mining scheme is adjusted according to the change of vein thickness and occurrence, thus reducing dilution rate, improving recovery rate and realizing continuous mining. Meanwhile, the technological measures such as deep shaft mining sequence, structure parameters, stope ventilation and cooling, drainage and ground pressure management are also expounded.
