Gas disaster is the principal enemy in coal mine production. In recent years ,The threat of gas disaster more prominent with the the further and high一intensity mechanized mining, the gas more emission, and a coal was nodanger of gas outburst into a dangerous coal seam.In this paper, in order to Tiefa of the Group Xiaoming coal mine for the study, through analysis the main impact factor on the content and emission of gas, combined with multiple linear regression methods、BP artificial nerve network methods, in order to predict the content、emission of nomining coal seams and paint the contour line.Though anslysis the drilling information and figure,combined with Fuzzy comprehensive evaluation,in order to establish the model of the coal and gas emission dangerous ,and get the evaluation results after calulation,which is disaster risk level.The last, divid region according to the disaster risk,paint deividing region figure of the coal and gas emission disaster risk,and propose proposal of preventing the coal and gas emission.
