摘　　要：依据野外调查取样测试数据,运用统计学方法,并结合前人水文地质、水化学研究成果,对抚顺西露天矿区地下水水化学参数的空间分布及演化特征进行全面分析。揭示了风化溶滤、氧化还原环境、阳离子交换和人为混合是控制地下水质演变的主要水文化学过程,从而为矿区排水的资源化利用和管理提供科学依据。Based on the latest field survey and sampling test data,the article analyzes the spatial distribution and evolution characteristics of hydrochemistry of groundwater in Fushun West Open-pit Mine by using statistical methods and combining with previous hydrogeological and hydrochemical studies,and reveals the main hydro chemical processes of controlling the water quality of the groundwater system:weather-dissolution,redox environments,ion-exchange reactions,mixing of surface water,which can offer the scientific guidance for the resource utilization and the management of drained water in Fushun West Open-pit Mine.
