摘　　要：文章利用FLAC数值模拟软件对采用锚杆支护的综采工作面回采巷道进行了数值模拟,详细分析了不同充填墙体宽度时沿空留巷的效果,从而得出沿空留巷充填墙体存在一个合理的宽度,当充填墙体达到这一合理宽度时,可以有效控制巷道围岩变形。The FLAC numerical simulation software was applied to the numerical simulation on the bolt supported mining gateway of the fully mechanized coal mining face. The paper in detail analyzed the effect of the gateway retained along the goaf with different backfill wall width. Therefore there would be a rational width existed in the backfill wall of the gateway retained along the goaf. When the backfill wall reached the rational width, the sounding rock deformation of the gateway could be effectively controlled.
