摘 要:基于褶曲构造影响下巷道易变形、冒顶等问题,以大通煤矿采区巷道为背景,结合围岩松动圈测试结果,研究了褶曲带巷道围岩变形规律,提出控制对策并进行试验。研究表明:巷道走向与褶曲轴线平行时围岩破坏厉害、冒顶概率增加;采用加长锚杆(索)能控制变形、邻近面切顶后减弱回采动压影响。Based on the issues of easy deformation and roof fall of roadways under the influence of fold structures,and taking the roadway in the Datong Coal Mine mining area as the background,combined with the test results of the surrounding rock loosening circle,the deformation law of the roadway surrounding rock in the fold zone is studied,and control measures are proposed and tested.The research shows that when the direction of the roadway is parallel to the fold axis,the surrounding rock is severely damaged and the probability of roof fall increases;The use of lengthening anchor rods(cables)can control deformation and weaken the impact of mining dynamic pressure after cutting the roof near the face.
