摘　　要：早子沟金矿区地下水较为丰富,可以再利用,但水质状况不明。本文选取矿区14个水样,11项水质监测指标,运用熵权法确定评价指标的权重,构建了基于熵权法的五元集对分析模型,对矿区2023年地下水水质状况进行了评价。结果表明:矿区浅层孔隙水水质较好,适宜用于饮用水源;因矿石矿物溶滤作用,井下基岩裂隙水水质较差,经处理后可供选矿用水。与单因子水质标识指数法相比,基于熵权的集对分析法评价结果更为客观、可靠,具有较好的适用性。成果可为矿山水资源综合利用和生态环境建设提供参考和依据。The groundwater in Zaozigou gold mine area is relatively abundant and can be recycled,but the water quality remains unknown.The researchers selected 14 water samples and 11 water quality monitoring indicators from the mining area.The entropy weight method is adopeted to determine the weight of the evaluation indicators,and a five-factort set pair analysis model based on the entropy weight method was constructed to evaluate the groundwater quality status in the mining area in 2023.The results indicated that the shallow pore water in the mining area has good water quality,which makes it suitable for use as a drinking water source.On the other hand,due to the leaching effect of ore minerals on the underground bedrock fissure water,harmful substances are dissolved into water,thus resulting in poor water quality.However,after undergoing proper treatment processes,it can be used for mineral processing.Compared with the single factor water quality identification index method,the Set pair Analysis method based on entropy weight demonstrates more objective and reliable evaluation results.it also has better applicability.The results can provide a reference and basis for the comprehensive utilization of mining water resources and ecological environment construction.
