Application of Multi-factor Comprehensive Analysis Method in the Regional Prediction of Coal and Gas Outburst

Through meticulous analysis of various factors affecting the coal and gas outburst by the multi-factor comprehensive analysis method,the defects of misjudgment caused by single factor can be effectively avoided,which improves the accuracy of regional prediction.Taking No.13-1 coal seam in the east NO.1 mining area of Dingji coal mine as an example,the coal seam outburst areas are divieded by using multi-factor comprehensive analysis method,which determines the danger zone of outburst and non-outburst.
