| 摘 要： | 以红四煤矿深井高应力巷道支护为例,在研究地应力状态、围岩强度、岩石成分的前提下,通过数值模拟方式确定了高预应力高强度高刚度锚杆锚索联合支护方案。通过对试验巷道变形移近量监测发现,两帮移近变形呈稳定状态的时间提前,巷道顶底板变形状况有所改善。

| Abstract: | Taking the support of high stress roadway in Hongsi Coal mMine as an example,on the premise of studying the state of in-situ stress,the strength of surrounding rock and the composition of rock,the combined support scheme of high prestress,high strength and high rigidity anchor cable is determined by numerical simulation.Through the monitoring of the deformation of the test tunnel,it is found that the deformation of the two sides is stable in advance,and the deformation of the roof and floor of the tunnel is improved. |
