深部巷道具有变形量大且持续时间长,四周来压,易受扰动和整体收敛的特点。该文分析了千米深唐口煤矿高应力南部轨道大巷的变形破坏特点及规律,提出了千米深井高应力巷道围岩控制技术。现场应用结果表明,采用左旋高强螺纹钢锚杆全长锚固配合锚网索喷永久支护的支护方式可有效控制围岩变形,实现巷道稳定。
深部巷道具有變形量大且持續時間長,四週來壓,易受擾動和整體收斂的特點。該文分析瞭韆米深唐口煤礦高應力南部軌道大巷的變形破壞特點及規律,提齣瞭韆米深井高應力巷道圍巖控製技術。現場應用結果錶明,採用左鏇高彊螺紋鋼錨桿全長錨固配閤錨網索噴永久支護的支護方式可有效控製圍巖變形,實現巷道穩定。

Deep roadway has the characteristics of large deformation, long duration, weighting all around, vulnerable disturbance and global convergence. The characteristics and laws of deformation damage of southern track roadway in Tangkou coal mine are analyzed, the high stress surrounding rock control technology of the deep well is put forward. The application results show that ： Sinistral high strength thread steel anchor with bolt - mesh - anchor permanent supporting support can control the deformation of the surrounding rock effectively, and realize the stability of roadway.
