摘　　要：结合中六大巷承压水上穿断层带掘进的特殊地质状况,提出了分阶段超前注浆的施工方法、针对性的注浆工艺,有效地增加了巷道围岩隔水层厚度,提高了断层带附近破碎围岩强度,保证了巷道安全快速掘进。Combined with the special geological conditions of tunneling through the fault zone over the confined water of Zhongliu roadway, the construction method of advanced grouting by stages and the targeted grouting technology are put forward, which can effectively increase the thickness of the waterproof layer of the roadway surrounding rock, improve the strength of the broken surrounding rock near the fault zone, and ensure the safety and rapid tunneling of the roadway.
