摘　　要：为解决煤岩互层复合顶板稳定性差、支护难度大的巷道支护问题,以某矿11-0031巷巷道支护为研究对象,根据巷道的破坏特征分析了破坏机理,在现场采用围岩控制技术改善巷道支护环境。通过现场监测,该技术解决了支护难题,提高了巷道围岩的安全性和稳定性,为矿井的支护设计提供了经验。In order to solve roadway supporting problems of coal and rock interbed composite roof,including poor stability and difficult supporting,taking 11-0031 roadway as the research object,failure mechanism was analyzed based on the destruction characteristics of the roadway.And surrounding rock control technology was adopted to improve the supporting environment of the roadway.On-site monitoring shows that this technology could solve the supporting problems,improve the safety and stability of the surrounding rock,and provide designing experience for other coal mines.
