As the production capacity of Liugou Mine increases, the originally gas management scheme was difficult to ensure the safe and orderly operation of the mine. In this paper, the gas extraction technology plan was analyzed for the working face of low permeability coal seam in Liugou Mine, the working face of No.3 coal seam was taken as the research object. The study showed that the gas extraction volume of No.3 coal seam working face increased significantly, from 6.6 m3/min to 14.48 m3/min, an increase of 119%; the gas extraction rate also increased significantly, from 18% to 40.5%. Therefore, the new extraction scheme can solve the problem of gas overrun and ensure the safe production at the working face of the mine.
