| 摘 要： | 摘要：本文利用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。该研究结果对沿空留巷有着重要的指导意义。

| Abstract: | AbstractThe paper used the FLAC numerical simulate software to make numerical simulation in the bolting Roadway of mining face，particularly analysed effect of gob-side entry retaining in the different width of roadside filling wall，accordingly put forward the reasonable width of filling wall，when the filling wall reached the width，it could effectively control the roadway surrounding rock deformation。The research has important direct meaning at the gob-side entry retaining. |
