摘要
针对古城煤矿N1303工作面沿空留巷,采用数值模拟的方法对不同柔模宽度的混凝土墙体进行了模拟,结果表明,在古城矿井的地质条件下,柔模墙体宽度为1.5m时,留巷效果最佳。同时采用该参数施工留巷1000m,效果非常好。数值模拟对煤矿沿空留巷相关参数的选择具有一定的参考价值,具有很大的推广应用前景。
The numerical simulation method was used to simulate the concrete wall with different flexible mode width on N1303 working face of Gucheng Coal Mine.The results showed that the soft mode wall had a width of 1.5 m under the geological conditions of the Gucheng Coal Mine.At the same time,this parameter is used to construct 1000m lanes,which is very effective.The numerical simulation has a certain reference value to the selection of relevant parameters along the empty lane of coal mine,and it has a great generalization value.
