掘进巷道过断层破碎带联合支护技术研究

Research on Combined Support Technology for Tunneling Through Fault and Fractured Zones

结合某矿掘进巷道过断层破碎带的结构构成情况提出联合支护技术要点,通过采取预注浆、U型钢架棚以及钢网喷联合支护工作方法,提高断层破碎带的支护工的效果,有效控制顺槽顶板的下沉速率,保证整个巷道掘进环境的安全性,为后续类似工作开展提供相关参考和借鉴。

Based on the structural composition of a certain mine excavation roadway passing through a fault and fractured zone,this paper proposes the key points of combined support technology.By adopting pre grouting,U-shaped steel frame shed,and steel mesh spraying combined support methods,the effectiveness of support work in the fault and fractured zone is improved,the sinking rate of the trough roof is effectively controlled,and the safety of the entire tunnel excavation environment is ensured.This provides relevant reference and reference for similar work in the future.
