摘　　要：针对现有灰色关联度计算模型存在的缺陷 ,提出了主观赋权法和客观赋权法相结合的灰色加权关联度综合评价方法。经实例分析 ,该方法可较好地反映出煤层顶板地质条件的灰色性特征 。Aimed at the defective in analysis model of gray correlation, the analysis model of weight gray correlation that the combine way of subjective decision and objective decision is put forward in this paper. Through examples in the paper, it is proved that weight gray correlation is a good way to react a gray feature in the geology condition of coal seam top rock,and it makes the analysing results more objective and more reasonable.
