摘要
为了改善CO2气爆致裂对煤层的增透效果,本文以霍尔辛赫煤矿五盘区集中回风大巷为研究背景,应用可控冲击波增透技术对使用过CO2气爆致裂的煤层进行了强化增透试验研究.在五盘区集中回风大巷共布置7个强化增透钻孔.通过增透孔、观测孔抽采效果的观察分析,表明在已实施CO2措施的区域,可控冲击波增透可以在一定程度上提高钻孔瓦斯流量,具有二次强化增透效果.
Abstract
In order to improve the anti-reflection effect of CO2 gas explosion fracturing on coal seams,this paper took the concentrated return air roadway in the fifth panel of Huoerxinhe Mine as the research background,and used the controllable shock wave anti-reflection technology to strengthen the anti-reflection experiment of coal seams which had used CO2 gas explosion fracturing.A total of 7 enhanced anti-reflection drilling holes were arranged in the concentrated return air roadway in the fifth panel.Through the observation and analysis of the extraction effect of the anti-reflection hole and the observation hole,it showed that in the area where the CO2 measures were implemented,the controllable shock wave anti-reflection could improve the gas flow rate of the drilling hole to a certain extent,and had a secondary strengthened anti-reflection effect.
