摘要
针对某矿5201大断面运输平巷的顶板控制问题,充分利用文献检索、现场调研、理论分析、数值模拟等工具,分析了围岩变形破坏机理,然后使用FLAC 3D数值模拟软件对巷道宽度对围岩破坏的影响情况进行模拟研究,最后设计5201大断面运输平巷的支护要点及具体支护方案,保障了巷道的正常生产使用及安全生产。
Aiming at the roof control problem of 5201 large section transport roadway in a mine,the deformation and failure mechanism of surrounding rock is analyzed by means of literature search,field investigation,theoretical analysis and numerical simulation.Then the influence of roadway width on surrounding rock failure is simulated by FLAC 3D numerical simulation software.Finally,the influence of roadway width on surrounding rock failure is studied.The supporting points and concrete supporting scheme of 5201 large section transport roadway are designed to ensure the normal production and safe production of roadway.
