基于AHP和可拓学理论的尾矿库安全评价 黄志平，苗作华 (武汉科技大学 资源与环境工程学院，湖北 武汉 430081) 摘要 以尾矿库安全事故频发为源头，首先运用层次分析法，选取安全评价指标并建立指标体系，将各层指标要素进行两两比较获取判断矩阵，通过一致性检验后得到总排序权重；然后运用物元理论，对所选指标根据实际情况以及参考文献划分等级标准，并对其进行无量纲标准化，同时选取合适的关联度计算公式；最后将实地获取的指标值进行无量纲标准化后，运用可拓学公式计算其单因素关联度和综合关联度，获得最终的安全等级。通过层次分析法获取更符合实际的权重使物元理论更加可靠，并充分利用可拓学中的精确特性对该尾矿库进行安全评价，为管理者提供一个科学有效的参考依据。 关键词 尾矿库 层次分析法 可拓学 权重 安全等级 The Safety Evaluation of Tailings Based on AHP And Extenics Theory HUANG Zhi-Ping,MIAO Zuo-Hua (School of Resources and Environmental Engineering,Wuhan University of Science and Technology,Hubei,Wuhan,430081,China) Abstract It’s for the source of frequent accidents in tailing. Firstly, it uses the Analytic Hierarchy Process method to select security evaluation indexes and build the index system. Then, making a pairwise comparison on the indexes of the layer to get the judgment matrix. It will obtain the weighs of the total sort when the matrix passes the consistency check. Secondly, making use of the Matter Element Theory to divided grading standards according to the actual situation and references. Then, making dimensionless standardization on it and choosing the right formulas of correlation at the same time. Finally, dimensionless normalize the the index value obtained in the field. After that, calculating its single factor correlation and comprehensive correlation degree by using extenics to get the ultimate level of security. It gets the more realistic weighs through the Analytic Hierarchy Process to make the Matter Element Theory more reliable and makes full use of precise characteristics among the Extenics Theory to make safety evaluation on the tailing. it gets the security level of the tailing and provides a scientific and effective reference for the managers. Keywords Tailing, Analytic Hierarchy Process(AHP), Extenics Theory, Weighs, Security Level. 尾矿库，在采矿工程中也叫尾矿场或尾矿池，在矿山生产中具有十分重大的作用，是其附属中最为重要的设施之一。尾矿库的功能大致相同，是把金属或非金属矿山在其生产过程中产生的不可避免的尾矿或者其他废渣堆放起来的场所。近年来，随着金属非金属矿山的大量开采，导致尾矿库的数量也越来越多。据统计，我国现有大大小小的尾矿库达13000余座，其中8
