在对巷道导水裂隙详细调查量测的基础上，通过对导水裂隙产状的归纳总结，结合涌水水样的温度、矿化度及氢、氧同位素的动态监测结果，分析了三山岛金矿两个矿区的渗流优势方位以及矿坑水与地表水体的连通性。研究表明：西山矿区的渗流优势方位与最大水平地应力平行，而新立矿区的渗流优势方位与最大水平地应力近于垂直；西山矿区存在海水、基岩咸水和第四系淡水的稳定补给，新立矿区的咸水和淡水补给量不断减小，海水补给量不断增大；新构造断裂对矿区渗流优势方位的控制作用大于采动裂隙，使得西山矿坑与地表水体存在良好的连通性，也控制着海水补给矿坑的方式；而新立矿仅在采动裂隙的影响下与海水、咸水和淡水存在较弱的连通性。

This paper is based on the detailed investigation of roadway water flowing fractures for the waterseepage.It analyzes the connectivity advantage of orientation and mine water seepage and surface water bodies oftwo gold mines at Sanshadao.It summarizes the distribution of crack occurrence,and gushing water sampletemperature,salinity and dynamic monitoring of the results of hydrogen and oxygen isotope.The study shows thatthe waterseepage dominant orientation in the district of Xishan mine is parallel to the maximum horizontal principalstress.The optimal direction of Xinli mine water seepage is nearly perpendicular to the maximum horizontalprincipal stress.The Xishan mine has stable recharge of seawater,rock saline,and Quaternary fresh water.In theXinli mine,the proportions of saline and fresh water in inrushing water in mine pits are diminishing gradually,asthe seawater increases.The role of neotectonic fractures in controlling the dominant orientations of mine waterseepage is stronger than that of fractures developed by excavation.The neotectonic fractures make the Xishan minehave well connectivity with surface waters and control the recharge process of the seawater.There is weaker connectedness between pits and surface waters in the Xinli mine which attributes to the mininginduced fractures.
