摘要
以霍州煤电庞庞塔矿9#煤仓及附近硐室的改造支护为工程背景,对巷道支护的特点进行了分析,并针对性地对给煤机硐室开口顶板、承重墙小断面通道、西区9#煤带式输送机暗斜井上段架棚强化段采取了相应的支护方式。工业性试验的结果表明,支护后的硐室围岩变形量较小,安全稳定性得到提高。
In this paper,the characteristics and roadway support are analyzed based on the reconstruction support of NO.9 coal bunker and nearby chamber of PangpangTa mine,Huozhou group,and the corresponding support methods are adopted for the opening roof of coal feeder chamber,small section channel of load bearing wall,and the reinforcement section of upper section of NO.9 Coal belt dark inclination shaft in Western District.Industrial test showed that the deformation of the surrounding rock of the chamber after support is small and the safety stability is improved,which can provide some reference for the support in similar cases.
