摘要
某矿井1531综采工作面属于"三软"煤层,根据该工作面瓦斯来源情况,采用分源治理、立体抽采技术进行瓦斯治理,工作面的瓦斯抽采率由以前的不足15%提高到68%,取得了良好的经济效益和社会效益,对于相似地质条件的矿井瓦斯治理具有较强的借鉴作用。
1531 fully mechanized coal mining face in a coal mine belongs to three soft coal seam. According to gas source of working face,adopts techniques of separating source management and dimensional gas drainage to control gas. The gas drainage rate from less than 15% increased to 68%,achieved good economic and social benefits,worth for reference.
