摘　　要：为解决云南大红山铜矿深部开采过程中可能存在的水害隐患,通过水文地质测绘、坑道调查、分层分段抽水试验、长期水文监测和水化学分析等方法,对矿区深部水文地质进行了系统分析。研究结果表明,大红山铜矿区地下水分水岭及流场与地表水一致,水文地质单元边界条件简单。主要充水含水层富水性弱,与地表水体及浅层风化含水层之间存在厚大且稳定的隔水层,水力联系微弱。采用数值模拟法预测了大红山铜矿-242 m标高丰水年正常矿坑涌水量为4024 m^(3)/d,旺雨季节矿坑涌水量为4856 m^(3)/d。这些发现为矿山深部防治水设计及治理提供了重要的地质依据。To address potential water hazard risks during deep mining at the Yunnan Dahongshan Copper Mine,a systematic analysis of the deep hydrogeological conditions was conducted using methods such as hydrogeological mapping,tunnel surveys,stratigraphic and segmented pumping tests,long-term hydrological monitoring,and water chemistry analysis.The results indicate that the underground water divide and flow field in the Dahongshan Copper Mine are consistent with surface water,and the hydrogeological unit boundary conditions are simple.The main aquifers have low water-bearing properties and are separated from surface water and shallow weathered aquifers by thick and stable aquitards,resulting in weak hydraulic connections.Numerical simulation predicts a normal mine pit water inflow of 4024 m^(3)/d at the-242 m elevation during peak water years and 4856 m^(3)/d during the rainy season peak.These findings provide critical geological evidence for deep mining water prevention and control design and management at the mine.
