摘要
针对101盘区准备巷道遇断层顶板冒落,通过分析查找原因,提出采用刚性支架、围岩注浆、管棚超前支护等措施确保巷道围岩稳定。现场应用结果表明,采用的技术措施可有效确保巷道围岩稳定,围岩变形在控制范围之内;为巷道的安全掘进及使用创造了良好条件。
Aiming at roof falling at panel 101,the paper proposes measures such as rigid support,surrounding rock grouting,pipe shed advanced support,etc.to ensure the stability of surrounding rock of the roadway.The field application results show that the adopted technical measures can effectively ensure the stability of the surrounding rock of the roadway and the deformation of the surrounding rock is within the control range,which has created good conditions for the safety tunneling and the usage of the roadway.
