伟峰煤矿6-#煤层瓦斯抽采技术研究

Gas Drainage Control Techniques in 6-# Seam of Weifeng Coal Mine

依据矿井在达产时瓦斯最大涌出量的预测,伟峰煤矿开采6#煤层时属于高瓦斯矿井。为了有效防范瓦斯事故并合理利用瓦斯资源,文章通过采用对本煤层预抽及边采边抽、邻近层高位钻孔抽采裂隙带、现采空区插管抽采和老采空区全密闭抽采的方法,从而达到煤与瓦斯安全高效共采的目的。

According to the prediction of max gas emission at largest production, Weifeng 6# coal seam belongs to high gas mine.In order to prevent gas accidents and use gas effectively, this paper pre pumping, draining while mining, adjacent layer high driling drainage fissure zone, new goaf intubation drainage and old goaf totally-closed drainage to realize the high-efficient exploitation of coal and gas.
