掘进巷道过断层支护工艺优化

Optimization of the Supporting Technology of the Tunnel through the Fault

通过技术研究对巷道原顶板支护进行了优化,对顶板进行深孔卸压,并采取了“加长锚杆+联锁组合锚索”的联合支护技术。通过实际应用效果来看,联合支护技术提高了断层应力区顶板稳定性,取得了显著应用成效。

Through technical research,this paper carries out deep hole pressure relief on the roof,and optimizes the original roof supportand adopts the combined support technology of"lengthening bolt+interlocking combined anchor cable".Through the practical application,the combined support technology improves the roof stability in the fault stress area,and has achieved remarkable application results.
