| 摘 要： | 针对31采区2#回风巷掘进揭露F2断层,在断层两侧存在破碎区,巷道围岩整体性较差问题,采用超前管棚支护+喷射混凝土作为临时支护,金属网+锚杆+锚索+π型钢梁联合支护作为永久支护的方案。监测数据表明,改进方案减小了围岩的变形量,使掉矸等不再发生,提高了安全性和工效。

| Abstract: | Aiming at the problem of F2 fault exposed by 2#return air roadway excavation in No.31 mining area,there are broken areas on both sides of the fault,and the integrity of roadway surrounding rock is poor,the advanced pipe shed support+shotcrete is used as temporary support,and the combined support of metal mesh+bolt+anchor cable+steel beam is used as permanent support.The monitoring data show that the improved scheme reduces the deformation of surrounding rock,makes the gangue fall no longer,and improves the safety and work efficiency. |
