立井井筒快速揭煤瓦斯防治技术及应用

Control Technology and Application of Rapid Coal Gas Extraction from Vertical Shaft

以五阳煤矿立井新井筒揭穿高瓦斯含量、高瓦斯压力煤层为背景,揭煤过程采用井筒周圈截流钻孔不间断抽采、冲扩孔增透、实时在线瓦斯抽采监测、及时效果评价等快速揭煤综合技术,保证施工连续,减少揭煤时间,实现了安全快速揭煤。

Taking the new well as the background to expose high gas content and high gas pressure coal seams in Wuyang Coal Mine,the coal extraction process uses continuous drilling and drilling,flushing and widening of holes,monitoring of real-time online gas extraction,and timely evaluation of the results. Reduction of coal extraction time,the realization of safe and rapid coal extraction.
