Abstract

Abstract:

In order to improve the level of tailing ponds management，an improved evaluating method for safety harmony equation of tailing ponds is used.Firstly,construct an evaluation system,included nine evaluation factors.Secondly,combined with the entropy weight method and the dynamic excitation evaluation method,the weight information interval of evaluation index was calculated and the evaluation index value is adjusted cooperatively,and the relative closeness is ranked.Then,the harmony degree of the tailing pond is calculated by using the theory of harmony equation.Finally,the degree of harmony of the comprehensive evaluation results,the ranking of the indicators and the factors affecting the safety,and the results give reasonable suggestions and improvement measures.

Key words: tailing ponds, entropy, dynamic excitation evaluation, harmony degree, safety evaluation
