摘 要:为满足破碎顶板复用巷道使用需求,以113033巷为研究对象,结合现场情况及邻近采面开采情况等分析了巷道围岩变形影响因素,并针对性提出了巷道修复技术方案。在对113033巷断面刷扩后,采用锚网索梁方式对巷道进行支护,同时在采面回采前采用深、浅孔注浆方式加固顶板及煤柱。工程应用后,113033巷围岩变形量大问题得以解决,可满足后续11303工作面回采需求。In order to meet the demand for the reuse of broken roof roadways,taking 113033 roadway as the research object,combined with the on-site situation and adjacent mining conditions,the influencing factors of roadway surrounding rock deformation were analyzed,and targeted roadway repair technology solutions were proposed.After expanding the cross-section of 113033 roadway,the roadway was supported using anchor mesh cable beam method.At the same time,deep and shallow hole grouting methods were used to reinforce the roof and coal pillars before mining.After engineering application,the problem of large deformation of the surrounding rock in 113033 roadway was solved,which can meet the subsequent mining needs of the 11303 working face.
