摘　　要：针对嘉禾矿浦溪井2152底板巷围岩受采动影响变形破坏极难控制难题,采用现场调研、数值计算等方法,查找围岩变形破坏的主因;运用数值模拟方法,分析得出该底板巷两帮的塑性破坏大于顶底板、帮部锚杆锚固位置处于塑性区之内,锚杆容易出现失效现象,原支护方案亟待优化改进;拟定“以变形锚杆、金属网、喷浆、锚索、全断面注浆”的一体化支护方案,并通过数值模拟验证其支护技术的合理性。In response to the extremely difficult problem of controlling the deformation and damage of the surrounding rock in the 2152 floor roadway of Puxi Well in Jiahe Colliery,this article adopts on-site research,numerical simulation and other methods to formulate an integrated support scheme of"deformation bolt,metal mesh,spray grouting,anchor cable,and full section grouting"to optimize the original support scheme,which verifies the rationality of its support technology through numerical simulation.
