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