Prediction method of coal and gas outburst using the grey theory and neural network

The grey theory and neural network method were applied to coal and gas outburst forecast. Main controlling factors of coal and gas outburst were filtered by the grey correlation method of the grey system theory. The mathematical model and systematic structure of artificial neural network were founded to forecast the risk of coal and gas outburst. The effectiveness of the risk forecast in the outburst zone of Pingdingshan No. 8 Coal Mine was demonstrated the grey theory and neural artificial network as a new means is available.
