摘要
为进一步提升煤矿生产的安全性和效率,以保兴煤矿11073工作面为例,在分析其地质条件的基础上,通过FLAC3D软件建立数值模拟模型并对其围岩稳定性进行分析,基于数值模拟结果和工作面的实际情况采用永久支护和强化支护方式对围岩进行联合控制,最后通过监测得知联合控制方案有效可行。
In order to further improve the safety and efficiency of coal mine production,based on the analysis of the geological conditions of 11073 working face,numerical simulation model was established and the stability of the surrounding rock was analyzed by FLAC3D software,and the joint control of the surrounding rock was carried out by permanent support and reinforced support based on the numerical simulation results and the actual situation of the working face,and finally the joint control scheme was found to be effective and feasible through monitoring.The joint control scheme was found to be effective and feasible through monitoring.
