新集二矿210108工作面试采期瓦斯治理技术研究

摘要

为探求淮南区域1煤层瓦斯治理技术，对新集二矿1煤层首采工作面采取了不同的瓦斯治理手段，通过分析比较工作面回采期间风排瓦斯、底板巷高负压抽采瓦斯、高抽巷抽采瓦斯、风机巷顺层孔抽采瓦斯以及采空区埋管抽采瓦斯，初步得到用于新集二矿1煤层瓦斯治理有效的技术手段，以为以后1煤层的安全开采提供参考。%In order to explore gas treatment technique in coal seam NO.1 of Huainan region,different gas control methods were taken in the first coal mining face of coal seam NO.1 in XinJi Mine Two.Through analysis and comparison of methane drainage by ventilation, floor roadway Gas drainage,gas floor roadway drainage,bedding hole gas drainage and pipe goaf gas drainage during working face mining, preliminary effective technology of gas governance for coal seam NO.1 in XinJi Mine Two,to provide reference for safe mining of coal seam NO.1.
