尾矿库安全评价的灰色关联与集对分析研究

从尾矿库安全管理所面临的实际情况出发，建立了尾矿库安全评价指标体系．利用AHP法确定了各指标的权重，根据联系数模型对尾矿库进行评价确定安全等级．应用灰色关联和集对分析的理论进行b、a与b、c两组集对的比较，将计算出的绝对关联度的最大绝对值作为差异度i的取值，代入各式中求出各组联系度的值，根据取值所在的安全区间分析分析尾矿库的安全等级的正确性以及发展的趋势，提出需要整改和加强的措施．此方法探索了一条尾矿库安全评价的新途径，为尾矿库的安全管理和运行提供了有效支持．

Safety evaluation of tailing pond based on gray relation and set pair analysis

According to the actual situation of safety management in tailings pond, the index system of safety evaluation was set up. With the use of AHP method to determine the value of each indicator, the safety level of tailing pond was deterined by the evaluation of correlation model. The gray relation model and set pair theory were applied to compare the set pair group of b, a factor with the group of b,c factor, then the calculated absolut maximum value of quantitative correlation was qualified as the value of i. By substituting the i value in each formula, the safety class and development trend of tailing pond were established which depended on the values of each group＇ s correlations, and the measures of rectification and strengthening were put forward according to the correlations. A new way of safety evaluation was explored in tailing pond to support safety of operation and management of tailing pond effectively.
