摘要
为了保证巷道施工质量,提高围岩稳定性,保证煤矿后期安全稳定生产,在复杂条件下的31115材料巷施工过程中采取了“注浆+桁架锚索+锚棚”等联合控制措施,有效控制了工程巷道围岩变形,保证了巷道施工安全,取得了显著成效。
In order to ensure the quality of tunnel construction,improve the stability of surrounding rock and ensure the safety and stability of production in the later stage of coal mine,the joint control measures such as"grouting+truss anchor cable+anchor shed"were adopted in the construction process of 31115 material roadway under complex conditions,which effectively controlled the deformation of surrounding rock in the engineering roadway and ensured the safety of tunnel construction and achieved remarkable results.
