摘　　要：通过对采场矿柱和顶板的稳定性影响机理研究,并采用REPA二维分析方法进行数值模拟分析,得到采场变形至最终破坏的整个过程,从而得到了采动损害的某些规律。为防止采场的破坏,需加大矿柱尤其是应力集中区的中间矿柱尺寸,并加强对矿柱顶、底部的监测。Based on the research of the stope stability and damage mechanism and the numerical simulation analysis with REPA two- dimensional analysis method,the whole process from stope deformation to damage is analyzed and so the rules of mining damage are found out. To prevent the destruction of mine,the pillar size should be increased,especially for the middle pillar in stress concentration area and the monitoring of its key parts on the roof and in the bottom should also be strengthened.
