摘　　要：山西金晖万峰煤矿有限公司副立井通过采用“井壁局部注浆加固法”修复罐道支座,解决了以往支座加固耐久性能差的问题。本工法从提高基材整体强度的着眼点出发,运用注浆充填加固方法,彻底解决了罐道支座锚杆锚固力不足的根本问题,消除了罐笼运行安全隐患,可为类似工程设计及施工提供参考借鉴。In the auxiliary shaft of Shanxi Jinhui Wanfeng Coal Mine Company Limited,by using"reinforcement of shaft lining by local grouting"to repair the shaft guide support,the problem of poor durability of support reinforcement in the past had been solved.Starting from the point of improving the overall strength of the substrate,the method of grouting and filling was used to completely solve the fundamental problem of insufficient anchoring force of the anchor rod of the shaft guide support and eliminate the hidden danger of the cage operation.It could provide reference for similar engineering design and construction.
