摘　　要：某矿为高瓦斯矿井,该矿3203综采工作面在回采各阶段分别应用了不同的瓦斯治理技术。通过对工作面瓦斯涌出量、以及工作面与回风瓦斯浓度、瓦斯抽采浓度、抽采纯量、抽采负压等参数的研究分析发现,开采保护层在高瓦斯矿井治理瓦斯问题上具有明显的瓦斯治理效果,利用高抽巷进行瓦斯抽采的效果要明显优于利用高位钻场进行瓦斯抽采的效果,在2段高抽巷接替使用期间预留出20~40 m接替距离可以确保瓦斯抽采取得较好效果。A certain mine is a high gas mine,and the 3203 fully-mechanized mining face of the mine has applied different gas control technologies in each stage of mining.Through the research and analysis of the gas emission from the working face,as well as the concentration of gas between the working face and the return air,gas extraction concentration,extraction purity,and extraction negative pressure,it was found that the mining protective layer has a significant gas control effect on the gas problem in high gas mines.The effect of using high gas extraction tunnels for gas extraction is significantly better than that of using high level drilling sites for gas extraction,setting aside a replacement distance of 20-40 meters during the use of the second section of high drainage roadway can ensure that gas extraction achieves good results.
