根据南山煤矿2号煤的地质力学条件,通过围岩稳定性分类给出锚固参数。通过数值模拟和工程实践等方法,系统研究了采动对巷道围岩移近量、离层量、塑性区及锚杆受力的影响规律。研究结果表明,围岩稳定性分析时应该考虑巷道的采动效应。研究结果对类似条件工程的支护技术具有一定的理论意义和实用价值。
According to the geomechanical conditions of 2# coal seam more reasonable supporting method and support parameters were ident stability of surrounding rock types. The influence laws of mining on su tion, roof separation, plastic zone and bolt force were systematically res vestigation and numerical sidered on the rock stabil has been adopted in Nans simulation. The results shows that the mining ity analysis. After several han mining area, showing of Nanshan Coal Mine, a ified on the basis of the rrounding rock deformaearched through field ininfluence should be consuccessful engineering practices, great theoretical and practical va the research lues to similar roadway support.
