摘　　要：利用FLAC3D数值模拟技术分析计算了许疃煤矿3233工作面在煤层回采过程中围岩的变形和应力分布规律,定量描述了煤层顶底板的采动效应。通过对煤层采动过程中顶底板的破坏形式及变形特征的研究,为许疃煤矿3233工作面的顶底板支护控制及采空区治理提供了理论依据。The basic principles of the numerical simulation software FLAC^3D were introduced. It was used to simulate the deformation of the surrounding rock and stress distribution. The underground mining effect of coal roof and floor in 3233 face was quantificationally analyzed. The results are consistent with actual deformation of surrounding rock. Based on the damage and deformation characteristics of coal roof and floor, we can control it in a scientific way.
