Abstract：With the rapid development of coal production technology, mine production capacity is greatly improved.Meanwhile, As the increase of mining depth of the coal mines, themine gas problem has been more and more serious. The gas has become the first restriction of coal mine safety. Based on the collection and analysis of gas geology information, predicted the Mine gas emission, analysis the outburst danger, demonstrated the necessity and feasibility of the the mine gas drainage, to draw the conclusion that No.6 colliery, Hemei Group Co. must be the establish an gas drainage system. Based on the analysis of Mine outburst and gas emission source, adoption the gas drainage from virgin areas coal seam, gas drainage while extraction and gas drainage from sealed goaf area that put to combined gas drainage method, also, I designed and processed the methods and parameters of the drainage method, chose the reasonable layout of drainage pipeline system, select a match with the drainage capacitygas drainage in the pump model and pump station, ancillary facilities. Then it makes the economic budget and the safety technical measures of whole gas drainage system. The gas drainage design of No.6 Colliery, Hemei Group Co. can eliminate the coal seam outburst danger, the gas accidents will be controlled, and achieving safe production.
