Research on Empowerment and Optimization of Green Mine Construction Evaluation Index
The development of green mining and the construction of green mines are an important platform and starting point for the implementation of eco-civilization construction in the mining field.Based on the analysis of the scores of selected green mines in 2020,296 green mines were selected,and the standard scores of 100 green mine construction evaluation three-level indicators were re-weighted by entropy weight method.The consistency degree and distribution characteristics of the results before and after weight optimization were analyzed by the head-to-tail consistency rate and K-S test method.The results showed that the index weight of Green Mine Construction Evaluation Index did not match the discretization of actual scores;compared with the original weight optimization,the evaluation total score ranking was in good agreement with the original result,and the differentiation between mines was increased.In order to improve the scientificity and operability of evaluation indexes,it is suggested to combine or reduce the repetitive evaluation indexes appropriately and adjust the weights of indexes appropriately.
