In order to solve the problems facing the previously used mining methods which are poor safety and high loss and dilution rate in a copper mine,this paper carried out experimental research on the downward horizontal slicing stoping method.This method advances from top to bottom layer by layer,the upper and lower layer approaches are in staggered layout,and the layered approach stoping is carried out in two steps.The field industrial tests showed that this method achieved the production capacity of 180 t/d,mining loss rate 8 %,dilution rate 6 %,mining cost at 103.30 yuan/t,and backfilling cost at 56.36 yuan/t,and it can meet the requirements of safe and efficient mining.
