摘　　要：针对双柳煤矿的瓦斯治理难题,首先对矿井201工作面的瓦斯涌出规律进行分析,梳理出工作面瓦斯来源主要包括三部分,一是煤壁瓦斯涌出,二是落煤瓦斯涌出,三是采空区瓦斯涌出,然后设计了巷道掘进期间瓦斯预抽、工作面回采期间超前预抽、采空区及上隅角瓦斯抽放的综合抽采方案,经工程实践及抽采效果分析,验证了瓦斯抽采方案的合理性及有效性,实现了预期的治理目标,保障了矿井安全生产。In view of the gas control problems in Shuangliu Coal Mine, firstly, the gas emission law of working face201 was analyzed, and the gas sources in the working face mainly included three parts: the gas emission from the coal wall, the gas emission from falling coal, and the gas emission from goaf. Then, a comprehensive gas drainage scheme was designed, including gas pre-drainage during roadway excavation, advanced pre-drainage during working face recovery,and gas drainage in goaf and upper corner, Through the engineering practice and the analysis of the drainage effect, the rationality and effectiveness of the gas drainage scheme have been verified, the expected governance goals have been achieved, and the mine safety production has been guaranteed.
