Abstract

At present,traditional evaluations of green mine construction mostly use a direct scoring method to evaluate the effectiveness of green mine construction.This method ignores the relationship between evaluation indexes and fails to fully consider the input-output efficiency of mining enterprises.This paper selected 24 specific indicators from four aspects of resource utilization,environmental protection,enterprise society,and technological economy to build an evaluation index system for the effectiveness of green mine construction in the gold industry.In addition,the input-output efficiency evaluation index system of green mine construction in gold industry was constructed by optimizing and screening efficiency index from input-output aspect.The interval analytic hierarchy process(IAHP) and entropy weight method(EWM) were used to obtain the subjective and objective combined weights of evaluation indicators,and the TOPSIS method was combined to build the green mine construction effect evaluation model for the gold industry.The input-output efficiency evaluation of green mine construction in the gold industry was analyzed by using the BCC model of DEA method.On the basis of effect and efficiency measurement,the efficiency-effect evaluation matrix was designed to facilitate the analysis of the degree of green mine construction and the benefits of gold mining enterprises.It helps to judge whether gold mining enterprises take efficiency into account during the process of green mine construction,and the results reflect the actual overall construction situation of gold mining enterprises.Through the case analysis of ten gold mining enterprises of the same type in Shaanxi Province,the results show that the effectiveness and efficiency of the ten gold mining enterprises are fluctuating and rising.The overall construction situation is good,and the input-output efficiency is superior to the construction’s effect.Among the ten gold mining enterprises,except for M2 and M9,the green mine construction of the other mining enterprises has reached a high status.The four mining enterprises,M1,M4,M5 and M6,have given consideration to the effect and efficiency,and the other mining enterprises should pay attention to the development of both in the future construction.The index system constructed in this paper considers the characteristics of green mine construction in the gold industry,and the economic and quantitative indicators improve the accuracy of the evaluation results.The effect-efficiency evaluation model strengthens the connection between indicators,and can evaluate and analyze the overall situation of green mine construction in gold mining enterprises.It provides a scientific basis for the improvement of gold mining enterprises.
