Abstract: Through analyzing the characteristics of gas occurrence in Qincheng Coal Mine, this paper shows that Qincheng Coal Mine has the necessary for building the gas drainage system, No. 2 seam is drainaged seam, which has the conditions of drainaging gas in coal seam. On the basis of prediction of mine gas emission volume for No. 2 seam and the coal mining conditions, this paper determines the reasonable gas drainage programs adapted for Qincheng coal mine finally.
