摘　　要：阳山金矿床位于甘肃省陇南地区,为一超大型微细浸染型金矿床,主要受安昌河—观音坝断裂带控制,矿区出露岩性主要为千枚岩、灰岩及斜长花岗斑岩。区内地下水及地表水补给、径流和排泄条件较简单,通过分析区内第四系孔隙水、层状岩类基岩裂隙水、块状岩类基岩裂隙水和构造带脉状裂隙水4种类型含水层,初步探讨了大气降水及各类含水层对矿床充水的影响,以及坑道涌水对采矿的影响,对于区内矿床涌水提出采取地表水防治结合矿坑水进行防治的建议,并对区内地下水的合理利用提出了初步建议,为下一步工作提供参考。Yangshan gold deposit is located in the Longnan area of Gansu Province,it is a very large micro-disseminated gold deposit,the deposit is mainly controlled by Anchanghe-Guanyinba fault belt.The lithology of this area are mainly phyllite,limestone and plagiogranite porphyry.The conditions of recharge,runoff and discharge of groundwater and surface water in this area is relatively simple,by analyzing the region quaternary pore water, layered rocks fissure water,bedrock fissure water and structure belt pulse-shaped fissure water,we discuss the impact of atmospheric precipitation and various types aquifers on the water-filled of the deposit,and take treatment to prevent water-filled using prevention of surface water,and combined with the mine water.At the same time,we propose the initial proposal for use of groundwater to provide a reference for the next work.
