Abstract: In order to more accurately predict the risk of coal and gas outburst,based on distance discriminant analysis theory,electromagnetic radiation forecasting index(electromagnetic radiation intensity E and pulse number N) and conventional index(R index,drilling gas inrush initial velocity q and drilling cuttings weight S)were regarded as discriminant factors,daily forecast data in April and May of heading face in Yanmazhuang mine was taken as training samples,and the distance discriminant analysis model of coal and gas outburst prediction of working face was established.The model was applied to analyze daily forecast data in June of the heading face,prediction results and the practical situation were approved,and the results showed that the method of distance discriminant analysis model was simple,prediction accuracy was higher than single indicator,and misjudgment rate was low,which realized the effective combination of the dynamic prediction and static prediction.This method in the coal and gas outburst prediction has good feasibility and practicability.
