摘要
文章运用CFD模拟软件,对钻孔预抽煤层瓦斯进行模拟,得出了最佳钻孔布置参数。经试验,用该方法指导的月亮田煤矿131015工作面,预抽煤层瓦斯抽放率从23.5%提高到49.11%,取得了很好的消突效果,对钻孔预抽煤层瓦斯具有一定的指导意义。
By applying of CFD simulation software, this paper simulates the pre - pumping coal seam gas drilling, and draws the layout parameters of the best drilling test, this method is used on 131015 face in Yueliangtian Coal Mine, the pre -pumping coal seam gas drainage rate has improved from 23.5 % to 49.11% ,which means it achieved good results, besides, it has a guiding significance of pre -pumping coal seams gas drilling.
