摘　　要：通过对水力压裂消突机理的研究,并利用RFPA2D-Integrated软件进行数值模拟,得出适合鹤壁八矿水力压裂的起裂压力和压裂增透范围。现场工业试验表明,实施水力压裂措施后,瓦斯抽放浓度平均提高了20倍,瓦斯流量提高了27倍,大大提高了瓦斯抽放的速度和效率,因此,水力压裂技术在低透气性突出煤层治理中能起到明显的增透、消突作用。With the study on the outburst elimination principle with hydraulic fracturing,the RFPA2D-Integraterd software was applied to the numerical simulation and the initial fracturing pressure and the fracturing and permeability improved scope were obtained suitable for the hydraulic fracturing in Hebi No.8 Mine.The site industrial trials showed that after the hydraulic fracturing measures conducted,the gas drainage density was improved by 20 times in average,the gas flow value was improved by 26 times and the gas drainage speed and efficiency were highly improved.Therefore,the hydraulic pressurized fracturing technology played obvious roles of the permeability improvement and outburst elimination in the low permeability outburst seam.
