摘要: 將灰色理論-神經網絡方法應用于煤與瓦斯突出預測中,利用灰色系統理論的灰色關聯法確定了控制礦井煤與瓦斯突出的主控因素,并對煤與瓦斯突出主控因素進行篩選.建立了煤與瓦斯突出危險性預測人工神經網絡的數學模型和系統結構.在平頂山八礦突出區進行了煤與瓦斯突出危險性預測應用,預測效果表明:利用灰色系統理論-神經網絡方法對預測礦井煤與瓦斯突出是可行的.Abstract: 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.
