中文摘要：
为了考察水力冲孔措施的卸压增透效果，以淮南矿业集团潘二矿11124工作面为试验点，通过考察水力冲孔单孔出煤量、冲孔前后抽采瓦斯体积分数、单孔抽采量以及冲孔前后钻孔瓦斯涌出初速度q等参数，分析了水力冲孔防突措施的卸压增透效果．实验结果表明，水力冲孔防突措施的卸压增透效果明显，抽采瓦斯体积分数由冲孔前的7．8％（平均）增至冲孔后的56．9％（平均），钻孔瓦斯涌出初速度也由冲孔前的24．2L／min（平均值）下降到冲孔后的2．28L／min，比原来下降90．57％．
英文摘要：
In order to study the relief effect of hydraulic flushing, taking Huainan mining group Pan II mine 11124 face as the experimental point, pressure -relief and pe＇rmeability incrpasing effect of hydraulic punching anti - outburst measures are examined by considering the coal amount of single - hole hydraulic flushing, the gas extraction volume fraction and single - hole extrattion, and the change of initial velocity of gas emission q before and after punching. The results Show that： The relief effect of conflict prevention measures in anti - reflective of hydraulic flushing is obvious. Exlraction gas volume fraction of the pre - flushing increases from an average 7.8% to an average of 56.9% after punching. The mean value 0. 029 5 m^3/min of gas emission of the early q alsos drop to 0. 085 7 m^3/min after hydraulic flushing, which drops 90.57% compared to the former.
