摘要
针对深部矿井高地应力复合顶板巷道围岩条件,通过系统的地质力学测试,结合现有锚杆支护理论、数值计算结果,确定了科学合理的设计方法和支护原则。现场试验表明,高预应力强力锚杆锚索支护系统能有效控制深部矿井高应力复合顶板巷道围岩变形与破坏,保证巷道支护效果,为工作面的安全顺利回采奠定了良好的基础。
According to the surrounding rock condition of the mine high stress roadway with the complex roof in the deep mine, with the systematic geological mechanics test, in combination with the available bolt support theory and the numerical calculation results, the scientific rational design method and support principle were determined. The site test showed that the high pre - stressed high strength bolt and anchor support system could effectively control the surrounding rock deformation and failure of the high stress roadway with the complex roof in the deep mine, could ensure the support effect of the mine roadway and could set up a good basis to the safety and successful mining of the coal mining face.
