摘　　要：根据五虎山煤矿近距离煤层群开采的特点,在分析矿井瓦斯赋存和涌出规律、计算工作面瓦斯涌出量的基础上,提出了"定向长钻孔区域预抽、邻近层卸压抽采、采空区瓦斯抽采"的适合近距离高瓦斯煤层群开采的分源瓦斯治理技术。该技术的应用使得矿井瓦斯涌出得到有效治理,确保了采掘工作面的安全高效生产。According to the characteristics of the contiguous coal seams group in Wuhushan Coal Mine,based on the analysis of the gas occurrence and emission laws and the calculation of the amount of gas emission in the working face,the seperating source control technology suitable for the mining of the gassy contiguous seams group was put forward,including＂the regional gas pre-drainage by directional long holes,the gas drainage by pressure relief of the adjacent layer,and the gas drainage from gob＂. The application of this technology has resulted in effective control of the mine gas emission and ensured the safe and efficient production of the working face.
