摘　　要：针对低透气性高瓦斯煤层采煤工作面瓦斯涌出量大、隅角瓦斯易超限、煤层瓦斯抽采困难等问题,通过高压注水,增加煤体裂隙,提高煤层瓦斯的可抽采性,在此基础上,采用瓦斯抽采、沿空留巷相结合的方法对赵官煤矿1701高瓦斯采煤工作面进行了瓦斯综合治理实践。According to the problems of large gas liberation,corner gas-over-limitation and hard gas extraction at high gassy coal face of low air permeability coal seam during production,by high pressure water injection increasing coal mass fracture to improve coal seam gas extraction.And then gas extraction and gob-side entry by using combined method of comprehensive gas control was used for1701 working face of Zhaoguan coal mine.
