摘　　要：针对显德汪矿1720工作面回风流瓦斯较高的问题,分析了造成瓦斯超限的主要因素,并就瓦斯含量高、涌出量大制定了相应措施,对工作面风量进行有效控制。实践表明,工作面未出现瓦斯超限,安全环境得到了改善。工作面风量保持在900 m^3/min左右,最大风量达1 087 m^3/min。Based on high gas in wind current of Xiandewang Mine 1720 working face, the overrun of gas was analyzed, the corresponding measures based on high gas and large emission were put forward, the air volume in working face was under control. The practice showed that working face was without gas overrun, safe environment was improved. Working face air volume was 900 m^3/min or so, the maximum reached 1 087 m^3/min.
