【摘要】 运用灰色理论建立巷道瓦斯涌出量的灰色模型,对贵州某矿矿井瓦斯涌出量进行预测预报.采用残差识别方法修正GM(1,1)模型进行瓦斯涌出量预测,预测精度更高.利用灰色灾变预测理论,对某矿矿井工作面瓦斯涌出资料进行分析、研究建立煤矿瓦斯涌出量灰色预测模型,并对矿井瓦斯涌出量变化趋势进行预测.通过建立灰色预测模型,进行矿井瓦斯涌出量灾变性预测.更多还原

【Abstract】 The grey system theory was used to establish the grey mathematic model for coal bed methane(CBM) emission quantity from the gateway in coal mine;then the CBM of a certain coal mine in Guizhou was forecasted by using this model.The GM(1,1) model modified by the residual error identification method was used to forecast the gas emission,achieving a higher precision.In addition,the gray prediction theory was also used to analyze the gas emission data and establish the gray prediction model.By using the established model,we can predict disastrous gas emission in coal mines.更多还原
