摘　　要：为了提高芦沟煤矿“三软”低透气性煤层瓦斯抽采效果,以矿井32141工作面为研究对象,研究了水力冲孔增透措施对“三软”煤层瓦斯抽采效果的影响,通过FLAC^(3D)数值模拟分析对比普通水力冲孔和多点水力冲孔对抽采效果的影响,根据模拟结果采用现场试验进行验证,结果表明:采用多点水力冲孔增透措施的钻孔瓦斯抽采效果显著提高,从而增强了矿井瓦斯防治能力。To improve the gas extraction effect of"three soft"low gas permeability coal seam in Lugou Colliery,taking 32141 working face as the research object,the paper studies the influence of hydraulic flushing measures on the gas extraction effect of"three sof"coal seam,analyzes and compares the influence of ordinary hydraulic flushing and multi-point hydraulic flushing on the gas extraction effect by using FLAC^(3D) numerical simulation,whose field results show that the gas extraction effect of borehole with multi-point hydraulic flushing measures is significantly improved,enhancing the gas control ability of mine.
