摘要
通过对影响围岩应力分布的几种开采参数(采宽、采深和采高)的数值模拟,得出了各种开采参数对围岩应力分布的影响规律,对于合理地设计工作面开采参数,正确经济地进行支护,安全高效地开采地下资源具有重要意义。通过在良庄煤矿51103工作面的现场观测和应用效果分析,可以看出数值模拟结果能够很好地指导现场实际生产。
By numerical simulating several mining parameters （mining width, mining depth and mining height） influencing stress distribution of surrounding rock, this paper presented influencing rule of those parameters, which was very important for rational mining design, correct and economical supporting and safety high-efficiency mining. Observation of 51103 Mining Face in Liangzhuang Colliery showed that numerical simulation result was fit for actual mining.
