摘要
以预测矿井瓦斯相对涌出量为研究目的,通过灰色系统的建模、关联度分析及残差辨识为基础,建立了灰色系统理论模型,并将该模型应用到某矿瓦斯涌出量预测分析中,对该矿历年来相对瓦斯涌出量进行了灰色生成,建立了灰色预测系统;由后验差检验结果、对照精度检验等级可知,灰色系统预测矿井瓦斯涌出量的拟合精度好,预测结果正确可靠,反映出了矿井瓦斯涌出量的客观存在与发展态势.
In order to predict the relative amount of mine gas emission, a model of grey system theory was built based on modelling grey system theory, analyzing association degree, and discriminating distinction. Used this model to analyze and predict the amount of mine gas emission and creating the grey emission amount of some coal mine, the grey predicting system of coal mine was built. It is shown that grey system theory can image the impersonality exit and develop posture of the amount of mine gas emission, because it has the virtue in link precision of forecast result due to checkout disoatch and comoarison orecision test degree.
