露天矿边帮压煤井工开采边坡破坏分析
|
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FLAC~(3D)软件建立矿山边坡模型,模拟不同开采情况下边坡岩体的位移情况,对边坡岩体的稳定情况进行分析,从而选择出最优的开采参数进行生产,保障矿井生产安全和最大的经济利益。
At the process of coal mining under slope, the stability of coal top rock mass directly affects the recovery rate of coal resources and the roadway safety. Through the mine geological data and mining status, using FLAC~(3D) software to establish the mine slope model, and simulate the displacement of rock slope under different mining conditions, stability analysis of rock slope. Select the optimal parameters of the mining production, ensuring mine production safety and maximum economic benefits.
