摘要
本文以贵州某矿为工程实例,对突出矿井煤层群开采瓦斯联合抽采技术进行分析,形成了针对矿井实际地质条件的瓦斯联合抽采技术。现场应用后,煤层瓦斯综合抽采率均可达到50%以上,工作面回风巷、上隅角瓦斯均在安全范围内。
This paper takes a mine in Guizhou as an example,the combined gas drainage technology of coal seam group mining in outburst mine is analyzed,the combined gas drainage technology is formed according to the actual geological conditions of the mine.After field application,the comprehensive extraction rate of coal seam gas can reach more than 50%,and the gas in the air return roadway and upper corner of the working face is within the safe range.
