| 摘 要： | 跃进矿冲击矿压属于典型的底板冲击矿压,针对底板冲击严重巷道单独采用锚网索支护防冲效果不好的现象,提出"O"型棚+锚网索联合支护方式。运用数值模拟方法对锚网索支护和锚网索+"O"型棚支护两种不同支护方式的底板变形、应力分布等进行模拟和矿井巷道变形实时监测数据分析,监测结果表明,锚网索+"O"型棚联合支护结构具有抑制冲击矿压的作用,适合在具有冲击矿压危险的巷道推广使用。

| Abstract: | The rock-burst of Yuejin Coal Mine belongs to typical rock-burst in floor strata.Aimed at a bad effect of bolt-wire mesh support for the roadways with serious floor outburst,the combined support by "O-shape shed and bolting-wire mesh" was put forward.The numerical simulation was used to study floor deformation,stress distribution and so on under two different supporting systems,and the real-time monitoring was carried out on the roadway deformation.The results showed that the combined support could inhibit the rock-burst and be widely applied to the roadways with rock-burst risk. |
