深井高应力煤巷锚网索梯次支护技术研究与应用

针对车集煤矿2310工作面两巷的地质特征，分析了大埋深高应力煤巷围岩的变形力学性质，提出了采用长短锚索、锚杆梯次支护的方案并实施，通过巷道位移观测论证了该方案的可行性。现场监测结果表明，巷道围岩变形量较小，支护状况良好；2310工作面两巷采用锚网索梯次支护参数选择合理，证明了梯次支护技术的可行性。

Research and Application of Anchor Wire Rope Arrangement Supporting Technology in High Stress Coal Roadway of Deep Mine

Aiming at geologic feature of up and down roadway of 2310 working face in Juji Coal Mine，this paper analyzed deformation mechanical property of surrounding rock in high stress coal roadway with large buried depth，the plan of using long and short anchor cable and anchor bolt to support in order was put forward and applied，which was proved to be a right plan to ensure the stability of roadway surrounding rock by the means of roadway displacement observation. The site monitoring results indicate that the deformation of surrounding rock is small and the supporting condition was good，which showed that the supporting parameters are reasonable and the anchor wire rope arrangement supporting technology is feasible.
