摘　　要：小厂坝矿区残留矿体赋存条件复杂且地压活动剧烈,为残矿的安全回收造成了巨大的困难。为了安全回采小厂坝采区65~71线残留矿体,首先对该区域的残留矿量进行了统计分析,掌握了残留矿体的空间分布特征。采用数值模拟对残留矿体回采前后的应力状态进行了分析,分析结果显示,残矿回收后,空区基本处于稳定状态。The residual ore body in the Xiaochangba mining area was complicated in conditions and the ground pressure activity was fierce,which created great difficulties for the safe recovery of the residual ore.In order to safely recover the residual ore body of the 65~71 line in the Xiaochangba mining area,the statistical analysis of the residual ore volume in the area was first carried out,and the spatial distribution characteristics of the residual ore body were mastered.The stress state of the residual ore body before and after mining was analyzed by numerical simulation.The analysis results show that after the recovery of the residual ore,the empty area is basically in a stable state.
