| 摘 要： | 在现场工程调查、岩体矿物分析实验的基础之上，分析并指出了巷道失稳破坏的原因是软化难度系数大、地应力水平高、围岩性质差，原支护设计不当。确认巷道围岩类型为高应力节理化膨胀性（HJS）复合型软岩。并确定了其变形力学机制及支护对策，进而对巷道返修提出了新的锚网索耦合支护设计。

| Abstract: | Base on the project site investigation and the rock mineral analysis test, the paper analyzed and pointed that the cause of the mine roadway unstable failure were large soft difficult coefficient, high ground stress level, poor surrounding rock property and improper original support design. The paper set up the deformation mechanism and support countermeasures and provided a new coupling supoort design for the mine roadway repair. |
