Abstract：The existing low concentration of gas extraction and pumping negative pressure being unreasonable and many other issues for a long time in Xinyuan coal mine,this paper optimized and newly established a set of evaluation index system and model for gas extraction system,and the parameters of gas drainage system at the coal mine were measured.According to analyze the measured parameters,the operation rules of production system of coal gas pumping were summed up at coal mine;at the same time,based on the analytic hierarchy process,fuzzy evaluation method to establish the system evaluation index system and model,which evaluated the coal mine.Finally,the corresponding optimization measures were put forward based on the analysis of the evaluation results and the running state and regularity of the mine.The conclusions successfully solve the problem of low gas concentration and explosion limit in coal mine gas drainage system,and improved the efficiency and safety of gas extraction.
