英文摘要：

Analysis and numerical simulation were conducted to study the stability of the typical stope roof and spacer pillar in the ore bodies in the ore belt of the deposit and the influence of the mining process on the mechanical behaviors of the surrounding rock by the finite element analysis software ANSYS. Short-hole shrinkage method and sublevel drilling and stope mining method were used in this mine,and the simulated results of the typical stope structural models at different mining methods were analyzed.For the current mining plan,the reasonable suggestions were proposed according to the analysis results and the mining production status so as to more precisely grasp the development and change regularity of different stope ground pressures,effectively carry out ground pressure management and achieve safe and efficient mining.
