摘要
为有效解决松散破碎围岩巷道变形严重、修复困难的问题,以两渡煤业轨道运输石门为工程背景,采用数值模拟确定了全断面锚注加固技术方案。试验结果表明,采用该加固技术后,巷道顶底板最大变形量125.5 mm,两帮的最大变形量105.7 mm,变形量较原支护方案下大幅度减小,巷道围岩变形得到了有效控制。
In order to effectively solve the problems of severe deformation and difficult repair of loose and broken surrounding rock roadways,taking the railway transportation crossdrift of Liangdu Coal Industry as the engineering background,a full section anchor grouting reinforcement technology scheme is determined by using numerical simulation.The experimental results show that after using this reinforcement technology,the maximum deformation amount of the roof and floor of the roadway is 125.5 mm,and the maximum deformation amount of the two sides is 105.7 mm.The deformation amount is significantly reduced compared to the original support scheme,and the deformation of the roadway surrounding rock is effectively controlled.
