Research on the evaluation system of green mines in gold industry based on the analytic hierarchy process
Establishing a differentiated green mine evaluation system for different types of mines is of significant practical importance.This study constructs a green mine evaluation system for the gold industry based on the analytic hierarchy process(AHP).The evaluation system sets the green mine evaluation index system for the gold industry as the target level,with 6 indicators as the criteria level such as mining area environment,resource development methods,and comprehensive resource utilization,22 indicators as the index level such as functional zoning,mine landscape,and mining area greening.The AHP method was employed to determine the weight ranking of different indicators,identifying important criteria levels such as resource development methods,energy conservation and emission reduction,and comprehensive resource utilization.As for the index level,key indicators include associated mineral resource utilization,green development,energy conservation and consumption reduction,mining recovery rate,beneficiation(metallurgy)recovery rate,and simultaneous mining and reclamation.The evaluation results provide a reference for the construction of green mines in the gold industry.
