| 摘 要： | 隔离矿柱在矿山开采中对维护矿山稳定具有重要的作用。结合某矿的实际情况，在矿山进入深部开采并转变采矿方法的过程中，采用极限平衡理论计算得出了隔离矿柱厚度为10 m。应用二维数值计算软件RFPA对其稳定性进行了分析研究。结果表明，留设10 m隔离矿柱可以维持采场的稳定，满足矿山生产的要求。

| Abstract: | Insulating pillar plays an important role in the stability maintenance of mine during mining. During the process of mining method change with the mining depth increasing，the limit equilibrium method is used to calculate out that the thickness of insulating pillar is 10 m according to the field engineering condition of a mine. With the use of 2D numerical calculation software RFPA，the mine stability is analyzed and the result shows that the 10-meter thickness insulating pillar can maintain the stability of stope and meet the demand of mine production. |
