| 摘 要： | 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。

| Abstract: | According to the geomechanical conditions of 2# coal seam of Nanshan Coal Mine,a more reasonable supporting method and support parameters were identified on the basis of the stability of surrounding rock types.The influence laws of mining on surrounding rock deformation,roof separation,plastic zone and bolt force were systematically researched through field investigation and numerical simulation.The results shows that the mining influence should be considered on the rock stability analysis.After several suc... |
