中文摘要：

针对林东矿业集团泰来煤矿＋1 150 m水平运输大巷受断层破碎带影响造成巷道围岩极不稳定的实际情况,采用现场调研、理论分析和数值模拟等方法相结合的方式对该类巷道围岩的变形破坏进行了调查和分析,并针对构造带围岩极其破碎的特点提出了锚网喷＋注浆＋顶板锚索的联合支护技术.该技术的支护原理为密集锚杆保持浅部围岩的整体性,注浆粘结强化破碎围岩,高刚度预应力顶板锚索控制围岩的失稳变形.通过数值模拟对巷道顶底板及两帮位移监测结果表明,该方案能够有效地控制围岩的变形破坏,使顶底板及两帮位移明显减小,能够满足矿井正常生产的要求.

英文摘要：

Caused by the faults,the surrounding rock of ＋ 1 150 m main haulage roadway in Tailai Coal Mine,which belongs to Lindong Mining Group is in the unstable state. According to the situation,by using the methods of field investigation, theoretical analysis and numerical simulation, the deformation and broken mechanism of this kind of surrounding rock have been analyzed and the support technology of anchor net spray ＋grouting ＋ anchor cable are proposed. The supporting principle of this technology is that keeping the shallow rock by intensive bolt,grouting reinforcement to bond broken rock and high stiffness pre- stress anchor cable control the unstable surrounding rock deformation. Engineering application shows that the technology can effectively control the deformation of tectonic belt that is extremely unstable surrounding rock roadway,and meet the requirements of normal use.
