Abstract: Mine environmental quality evaluation is a work that has orientation and practical significance in the field of environmental protection.A scientific and objective evaluation result not only can guide the mine environmental protection and treatment policy,but also can promote the rational exploitation of mineral resources.Because different mines are in different stages of exploitation,their environment problems are complicated and various.The grey relational analysis method is very practical in environmental quality evaluation for a huge amount of mines.In this paper,the authors use EXCEL data processing to remedy the defect of limited samples in the grey relational analysis method.Taking mine environmental quality evaluation in Jiangxi Province as an example,this paper analyzes the cause of mine environment problems and makes a systematic discussion on the method and model of evaluation based on the grey relational analysis.12 evaluation indexes related to environmental background and environmental damage of the single mine are selected to evaluate the weights of indexes and quality grading taking all the mines in Jiangxi Province as examples,and in combination with the comprehensive index method,the mine environmental quality grades are determined for various mines,respectively,thus providing a scientific basis for mine environmental protection and control.
