| 摘 要： | 以辛置煤矿2-559工作段面沿空留巷为例,对其新型沿空留巷技术采用的不同支护方案用有限差分进行了模拟,结果显示单纯采用锚杆锚索对开挖巷道进行支护,不能有效控制巷道变形,如同时结合桁架,能有效控制巷道形变。

| Abstract: | With the gob side entry retaining in 2-559 working face of Xinzhi Coal Mine as an example, the different support schemes used in new technology of gob side entry retaining are simulated using finite difference. The results show that supporting roadways only by using anchors and bolts cannot control the deformation of roadway effectively, only if the trusses are combined with. |
