摘要
通过对高能气体压裂技术在煤矿井下现场试验过程中的煤层瓦斯流量衰减系数α、透气性系数λ、瓦斯含量、抽采钻孔有效抽采半径等变化规律,综合研究、分析可知:高能气体压裂技术可以适用于类似乐平涌山桥矿区赋存条件的煤层,提高煤层透气性系数和瓦斯抽采率,缩短预抽煤层时间,防止煤与瓦斯突出事故的发生.
Through the changes of coal seam gas flow attenuation coefficienta, permeability coefficient λ, gas content, effective extraction radius of drilling hole, etc., this paper makes a comprehensive research and analysis, hshows that the high energy gas fracturing technology can be applied to coal seams similar to the existing conditions in Leping Yongshanqiao mining area, improve the permeability coefficient and gas extraction rate of coal seams, shorten the pre-pumping coal seam time, and prevent coal and gas outburst accidents.
