三交河煤矿11-001综采工作面瓦斯治理研究及应用

Research and application of gas control of 11-001 fully mechanized working face in Sanjiaohe Mine

以三交河煤矿11-001工作面U型综采工作面为研究对象,通过对本煤层瓦斯参数的分析,判断煤层抽放的合理性,利用高位钻孔瓦斯抽采技术以及不同步距埋管抽采方案,对上隅角瓦斯浓度和抽放管路中瓦斯浓度进行分析,得出了抽放的合理性及埋管步距的合理参数,为三交河煤矿开采11号煤层的瓦斯治理工作提供实践依据。

U type fully mechanized working face of 11-001 fully mechanized working face in Sanjiaohe Mine was taken as example, the gas parameters of current coal seam was analyzed to judge the reasonability of coal seam drainage, high-position gas drilling and different step of buried pipe technology was adopted to analyze the gas content in upper corner and drainage pipeline, the reasonable parameters of gas drainage and buried step were got, providing reference for gas control in No. 11 coal seam of Sanjiaohe Mine.
