Abstract: Aimed at the fact that coal and gas bursting is a geological dynamic phenomenon influenced by multi factors,the hierarchy analysis model of coal and gas bursting is built up and the weights of influence factors are confirmed by taking the mining faces of eastern 3 collieries（8th,10th, 12th Colliery） of Pingdingshan Mine Area for examples.The fuzzy comprehensive evaluation model for the forecast of coal and gas bursting is set up and different degrees of bursting danger are classified to provide scientific basis for the prevention and control of coal and gas bursting.
