煤与瓦斯突出强度预测的BP神经网络模型

煤与瓦斯突出是危害煤矿安全生产的主要因素,因此做好煤与瓦斯突出特别是突出强度的预测,为针对性的采取防突措施,防止突出事故的发生,减小突出所造成的危害具有重要的指导作用。通过对新安煤田二1煤层突出特征的统计分析和瓦斯地质规律的研究,找出了煤与瓦斯突出强度预测的主要影响因素。应用人工神经网络的有关知识,结合其主要影响因素建立适合于新安煤田煤与瓦斯突出强度预测的BP人工神经网络预测模型。并通过误差分析验证了该模型的正确性。

Strength of Coal and Gas Outburst Forecast of BP Neural Network Model

The coal and gas outburst is the key factor of the coal mine safety.So it is more important to predict the coal and gas outburst especially the coal and gas outburst scales to adopt measures on purpose,prevent the coal and gas outburst and reduce the harm that the coal and gas outburst causes.According to the research of the law of gas-geology and the feature of coal and gas outburst of Xin'an coalfield No.2-1 coal seam,we would find the key factor of the coal and gas outburst scales.Then we would found the...
