摘要
边帮压煤井工开采过程中,煤层顶板上部岩体的稳定性直接影响到煤炭资源的回收率和巷道安全。根据矿山地质资料与开采现状,运用FLAC3D软件建立开采模型,模拟不同开采情况下煤层顶板应力分布状况,对煤层顶板稳定性进行预测,从而选择出最优的开采参数进行生产,保障矿山生产安全和最大的经济利益。
At the process of coal mine under slope,the stability of coal top rock mass directly affects the recovery rate of eoal resources and the roadway safety.Through the mine geological data and mining status,using FLAC^3D software to establish the mining model,and simulate the displacement of coal top rock stress distribution,to predict the roof stability of the coal seam,select the optimal parameters of the mining production,ensuring mine Droduetion safety and mountain maximum economic benefits.
