Abstract: 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.

Key words: Residual ore recovery, Numerical simulation, Stress distribution, Deep recovery
