基于AHP的灰色聚类法的煤中铝、镓资源评价体系

Evaluation of Al,Ga resources in coal measures based on AHP-GCA method

摘要: 铝、镓资源是重要的战略性矿产,在煤中广泛分布。目前对煤中铝、镓资源研究日益增多,但尚未形成科学合理的资源评价体系。根据煤中铝、镓资源特征确定出影响其资源评价的10项主要指标,采用层次分析法与灰色理论评价方法相结合,构建出煤中铝、镓资源评价模型。通过专家打分方法,确定出各指标因素对煤中铝、镓资源条件影响权重,并结合当前对煤炭和伴生资源研究现状及相关规定对评价指标进行了赋值。

Abstract: Al and Ga resources,widely distributed in coal,are important strategic mineral resources. At present,re- search on Al and Ga resources in coal measures increases,but it has not formed a scientific and reasonable evaluation system. Based on the characteristics of Al and Ga resources in coal,authors identified 10 main indexes for the evalua- tion of Al and Ga resources in coal,and built an evaluation system model using AHP-GCA method. Using the scores given by experts,the authors can identify the indexes factors weights of Al and Ga resources in coal. Combining with the current research of coal and associated resources and related regulations,the authors assigned the indexes.
