摘要:
针对贵州湾田煤矿多次动压作用巷道围岩变形破坏严重的问题，提出了巷道围岩“三区”强化支护控制技术，通过数值模拟、理论分析和现场试验研究分析了围岩“三区”强化支护效果。研究结果表明：通过内外注浆方法在巷道围岩内形成围岩锚固区、围岩强化区和应力释放区，并将注浆区域分为内注浆区和外注浆区，使其之间形成动压缓冲区；注浆能够有效的胶结破碎围岩体，锚杆锚索所处的塑性破坏区得到了有效重新加固，形成具有高强度的承载拱；井下现场监测数据表明巷道顶板下沉量和底鼓量不足巷道高度的5%，两帮变形量仅为巷道宽度的0.7%，有效地控制了巷道围岩的变形破坏。
Abstract:
Aiming at the problem of serious deformation and failure of the roadway surrounding rock under the effect of multiple dynamic pressures in Guizhou Wantian coal mine, the reinforced support and control technology of “three zones” in the roadway surrounding rock was put forward, and the effect of reinforced support of “three zones” in the surrounding rock was analyzed through the numerical simulation, theoretical analysis and field test. The results showed that the surrounding rock anchorage zone, the surrounding rock reinforcement zone, and the stress relief zone formed in the roadway surrounding rock by the internal and external grouting method, and the grouting zone was divided into the internal grouting zone and external grouting zone to form the dynamic pressure buffer zone between them. The fractured surrounding rock mass could be effectively cemented by the grouting, and the plastic failure zone where the anchor rod and anchor cable located was effectively reinforced again to form a highstrength bearing arch. The underground field monitoring data showed that the roof subsidence and floor heave of the roadway were less than 5% of the roadway height, and the deformation of both sides was only 0.7% of the roadway width, so the deformation and failure of the roadway surrounding rock were effectively controlled.
