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。

Abstract:

Based on the surrounding rock conditions of deep mine Roadway with Composite Roof, and the results of geo-mechanical on-site tests, combined with Existing bolting-support theories and Numerical calculation results, the Scientific and rational design method and supporting principles were determined. It was proved that the high strength bolting system can effectively reduce the deformation and destruction of roadway with composite roof in deep mine. The supporting system laid the great foundation for the coal mining face fast and safely recovery.

Key words: supporting system with high strength, deep mine with high stress, composite roof, supporting design and application
