| 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。应用数值模拟和工程实践等方法,系统研究了埋深对巷道塑性区、应力分布及位移分布的影响规律。研究结果表明,围岩稳定性分析时应该考虑巷道的埋深效应。研究结果有利于了解巷道围岩内部应力与位移的发展规律,为选择巷道锚固方案和优化锚固设计参数提供了依据,可为类似条件矿井的支护提供理论依据与应用性指导。 |

| Abstract: | According to the geomechanical conditions of 2# coal seam of Nanshan Coal Mining,a more reasonable supporting method and correspending support parameters were identified,on the basis of the stability of surrounding rock types.The influence of roadway depth on surrounding rock plastic zone,stress distribution and deformation was systematically investigated through field investigation and numerical simulation.The results show that the depth effect should be considered in rock stability analysis.The research r... |
