摘　　要：在高瓦斯矿井和煤与瓦斯突出矿井,对巷道封闭区进行瓦斯排放是矿井安全管理工作中一项极为重要的内容。传统的启封密闭排放瓦斯方法,在排放瓦斯浓度控制等方面存在很大的安全隐患,国内煤矿企业也曾多次因排放瓦斯而发生事故。基于此,提出了压风置换瓦斯排放方法,并在现场进行了实践应用,实现了安全快速排放瓦斯的目的。In high-gas or coal and gas outburst coal mine,the gas drainage in roadway closed areas is an extremely important part of coal mine safety management.The traditional gas drainage method of unsealing confined has big hidden danger in the concentration control of gas drainage,and the domestic coal mining enterprises have repeatedly happened gas drainage accidents.Base on this,the technology of pressure air replacement gas drainage is proposed in the paper,which achieves the purpose of safe and fast gas drainage by putting it into practice.
