Application on upward horizontal slicing cemented backfill mining method in Gongbei gold mine

Upward horizontal slicing cemented backfill mining method has the following characters:ore morphological changes of strong adaptability, high degree of mechanization, great capacity of production, more plan of recovery, strong flexibility, simple structure, easy cutting, cutting work than small, not easy to form the overdraft or underbreak, low loss of ore, low rate of dilution and so on, especially suitable for the conditions of complex mining technology in precious metal ore. This paper focus on recovery and filling process of the mining method, which is expected to bring multiple benefits.
