摘　　要：采用数值分析软件ANSYS对某矿体典型采场顶板与间柱的稳定性及其对采场围岩力学状态的影响进行数值模拟分析,矿山采用浅孔留矿法和分段凿岩阶段矿房法对于不同产状的矿体进行开采,对不同采矿方法下典型采场结构模型的模拟结果进行了分析,根据分析结果,结合矿山生产现状对目前采矿方案提出合理化建议,以便更确切地掌握不同采场地压的发展变化规律,有效地实施地压管理,实现安全高效开采。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.
