摘　　要：和尚桥铁矿是一个大型露天磁铁矿,由于矿区的特殊位置,建设生态矿山、最大限度地减少矿山生产对环境的扰动势在必行。矿山工业布局、独特的水文地质环境和安全生产需要,均给矿山地下水疏干提出新要求。根据该铁矿露天采矿场不同地段的地质、水文地质和工程地质条件,提出了地表和地下联合疏干的方法。利用所建立的地下水疏干预测模型,模拟该方案疏干矿坑地下水的可能,为矿山安全生产、地下水综合利用提供决策依据。The Heshangqiao iron mine of the Nanshan Mining Co. Ltd.,Ma＇anshan Iron and Steel Group is a large open-pit magnetite mine with a special position. It is therefore imperative to construct ecological mining,in order to minimize the environmental disturbance of mine production. The mining industrial layout,unique hydrogeological environment and mine production safety make new demands on groundwater drainage. Based on the geological,hydrogeological and engineering geological conditions of different sections in the Heshangqiao open-pit mine of Ma＇anshan,this study proposed a combined method of ground with underground drainage. We then use the groundwater dewatering forecasting model to simulate groundwater drainage,and provide basis for decision-making of mine safety production and groundwater utilization.
