摘　　要：有效的瓦斯抽采是高突矿井安全生产的重要保障,而煤层透气性系数是影响瓦斯抽采效果的重要参数。基于增加煤层透气性的需要,结合东庞井21112工作面现场情况,实施了本煤层水力压裂增透试验。通过试验,基本确定了适用于东庞井2号煤层的水力压裂技术参数,减少了抽采钻孔量,节约了成本,提高了本煤层抽采钻孔的瓦斯浓度与纯量,本煤层瓦斯抽采效果显著提升。Effective gas drainage guaranteed safety production of high outburst mine, and permeability coefficient of seam was an important parameter for gas drainage effect. Seam hydraulic fracturing antireflection test was implemented combining with site conditions of 21112 working face in Dongpang Mine to satisfy need of increasing seam permeability. Based on experiments, basic parameters of hydraulic fracturing antireflection technique which was suitable for Dongpang Mine 2#seam was determined, borehole volume and costs were reduced, concentration and scalar of borehole seam methane in current seam together with drainage effect were significantly improved.
