摘　　要：矿井煤层瓦斯含量与煤层埋藏深度、围岩性质等密切相关,以不同煤层地质参数及其相对瓦斯含量数据为原始序列,通过灰色处理建立微分方程预测模型,使用GM(1,4)灰色预测模型建立了未开采区瓦斯含量的预测方程,并进行了残差检验。同时对不同因素对瓦斯含量的关联程度进行了分析。Coal seam gas content is related to the depth of the coal seam,rock property of coal seam and so on.In this paper data of various coal seam geological factors and its according content of coal seam methane are used as initial sequence,grey forecasting model is established based on gray processing,which is used to set up the forecasting foumula of the unmined area,and the fault test is conducted.Meanwhile the relativity of different factors on content of coal seam methane is also analyzed.
