霍尔辛赫煤矿可控冲击波强化增透试验研究

Study on controllable shock wave strengthening and anti-reflection experiment in Huoerxinhe Mine

为了改善CO_(2)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CO_(2)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CO_(2)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。

In order to improve the anti-reflection effect of CO_(2) 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 CO_(2) 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 CO_(2) 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.
