瓦斯抽采是矿井瓦斯治理的重要手段,瓦斯抽采方法应根据矿井开采现状、煤层的赋存特点、煤层顶底板岩性情况、现场施工及成孔条件等因素进行合理设计。以贝勒煤矿为例,从区域预抽煤层瓦斯抽采、采掘工作面瓦斯抽采、采空区瓦斯抽采等方面设计了瓦斯抽采方法,以促进矿井安全、经济、高效生产。
Gas drainage is an important means of gas control in coal mine. The gas drainage method should be properly designed according to the status quo of coal mining, the occurrence characteristics of coal seam, the lithology of roof and floor of coal seam, site construction and hole formation conditions. Taking Bayler Coal Mine as an example, a gas drainage method was designed from the aspects of gas drainage in the area of pre-pumping coal, gas drainage in the mining face and gas drainage in the goaf to promote the safe, economical and efficient production of the mine.
