摘要
针对高瓦斯矿井综放工作面瓦斯涌出量高,治理难度大的实际情况,以山西寿阳潞阳麦捷煤业有限公司150316综放工作面为研究对象,提出了采用"本煤层预抽+裂隙带抽采+高抽巷抽采"的瓦斯综合治理方法来治理工作面瓦斯。实践表明,通过该方法的应用,回风巷瓦斯浓度不足0.40%,工作面瓦斯抽采率80.1%,抽采达标且抽采效果良好,具有较好的推广应用价值。
Based on large gas emission and difficult control of fully mechanized working face in high gas mine, 150316 fully mechanized working face of Shanxi Shouyang Luyang Microgate Coal Corporation Ltd. was taken as study object,comprehensive gas control measure of current coal seam pre-drainage ＋ fracture drainage ＋ high drainage was put forward,the practice showed that the technology enables to reduce gas content to less than 0.40%, gas drainage rate 80.1%,achieving the standard, with good drainage effect and promotion value.
