摘要
本文将xx煤矿xx运输大巷的变形破坏问题作为研究对象,对巷道出现的变形破坏问题进行了研究分析,得到导致巷道出现大变形破坏的主要原因是巷道所处地段的工程地质条件较为恶劣、巷道围岩强度整体偏低、巷道围岩的自身承载能力并没有充分发挥出来等。根据现场勘探和理论分析,提出了高预应力耦合支护方式,设计了返修支护方案。从高预应力耦合支护理念在巷道返修中的使用情况来看,巷道整体得到了有效的稳定控制,对类似巷道支护有一定的借鉴作用。
This article takes the deformation and failure problem of xx transportation roadway in xx coal mine as the research object,and con-ducts research and analysis on the deformation and failure problem of the roadway.It is found that the main reasons for the large deformation and fail-ure of the roadway are the harsh engineering geological conditions of the location of the roadway,the overall low strength of the roadway surrounding rock,and the insufficient bearing capacity of the roadway surrounding rock.Based on on-site exploration and theoretical analysis,a high prestressed coupling support method was proposed and a repair support plan was designed.From the application of the high prestressed coupling support con-cept in tunnel repair,it can be seen that the overall stability of the tunnel has been effectively controlled,which has a certain reference value for sim-ilar tunnel support.
