摘要
本文针对高河煤矿W1309工作面3号煤层存在的高瓦斯问题,提出“Y+高抽巷”的瓦斯治理模式。并以W1309高抽巷Ⅱ段为例,提出了瓦斯抽放设计,并对不同回采阶段高抽巷的瓦斯抽采效果、抽采特征进行分析。结果表明,W1309高抽巷Ⅱ段对回采期间的瓦斯抽采效果明显,有效控制了工作面回采期间的瓦斯浓度。
In this paper, the gas control mode of "Y+ high gas drainage roaway" is proposed for the high gas problem existing in No. 3 coal seam of W1309 working face of Gaohe Coal Mine. Taking the section II of the W1309 high gas drainage roaway as an example, the gas drainage design is proposed, and the extraction effect and extraction characteristics of high gas drainage roaway in different mining stages are analyzed. The results show that the section II of the high gas drainage roaway of W1309 has obvious effect on gas drainage during the mining period, and effectively controls the gas concentration during the mining of the working face.
