金属地下矿山缓倾斜薄矿体采矿方法优化选择及应用OA

Due to the scattered occurrence and limited mining space,traditional methods such as comprehensive mining,room and column mining,and shallow hole retention mining in metal underground mines have problems such as low resource recovery rate,poor safety,and low efficiency.This study proposes an optimization approach of"geological adaptation intelligent empowerment comprehensive evaluation"based on the occurrence conditions of the ore body.Mining methods are selected according to the differences in dip angle,thickness,and surrounding rock stability,and intelligent equipment is integrated to improve efficiency.A three-dimensional evaluation system of"recovery rate safety cost"is constructed and verified with a case study of a copper mine.The results indicate that optimizing the room and pillar method can improve resource recovery rate,reduce accident rate,and enhance comprehensive benefits,providing practical reference for the mining of similar ore bodies.
