| 摘 要： | 运用污染负荷芘和灰关联法递阶分析了矿山地下水污染物的主从关系，确定了矿山地下水的主要污染指标；应用灰色聚类对矿山地下上水质量进行了评价。结果表明，矿山排放废物的渗入量是矿区地下水质量恶化的主要原因；矿山的选冶方法、技术水平及废物处理率是影响地下水环境特征的主要因素。

| Abstract: | This paper analyses the principal and subordinate relationship between groundwater pollution indexes by using pollution load ratio and gray relation analysis method.The major pollution indexes of mine groundwater are identified and the evaluation of mine groundwater quality have been made by using gray cluster analysis.The result indicates that infiltration quantity of draining waste material is main pollution source of the quality worsening of groundwater;the milling method,the technical standard and the handing ratio of waste material are main factors which affect groundwater surroundings feature. |
