摘要
文章在FLAC软件数值模拟的基础上,对沙曲矿掘进巷道随掘随抽方案钻孔参数进行了合理调整,经实践监测提高了钻孔瓦斯抽采的效果,降低了煤层突出威胁,加快了巷道掘进,具有重要的工程实践意义。
This paper, on the basis of FLAC numerical simulation, adjusts the drilling parameters of synchronizing drifting of Shaqu mine. The experiment proves that the efficiency of the gas extraction is raised, the threat of coal outburst is reduced and the drilling is accelerated. The study is of great importance.
