Coal and gas outburst pattern recognition and possibility prediction of Panyi Mine

The regional geological fault was determined by the geo-dynamic zoning method. Based on analyzing the relations between the influential factors and the dangerousness of coal and gas outburst, a muti-factor model of pattern recognition was established. The pattern recognition method was applied to predict the regional hazard of coal and gas outburst. Panyi mining area was then divided into the coal and gas outburst dangerous area, threatening area and safe area to assess and predict the hazard of coal and gas outburst. The prediction accuracy of gas in coal and gas outburst was improved.
