摘　　要：本文针对龙泉煤矿低透气性厚煤层高瓦斯抽采难度大等问题,在回采工作面采用瓦斯综合治理技术并进行研究。实践结果表明,该技术的实施使工作面易积聚的上隅角瓦斯浓度、回风流瓦斯浓度均保持在0.3%以下,瓦斯抽采率达到60%以上,成功解决了低透气性厚煤层高瓦斯回采工作面瓦斯超限的问题。This paper studies the comprehensive gas control technology used in the high gas mining face of low permeability thick coal seam in Longquan Coal Mine.The practical results show that through implementation of this technology,the gas concentration of the upper corner and the return air flow in the working face is kept below 0.3%,and the gas extraction rate is above 60%,which successfully solves the problem of gas overrun in the high gas mining face of low permeability thick coal seam.
