辽宁省三道河金矿床的水文地质特征

Hydrogeological Characteristics of Sandaohe Gold Deposit in Liaoning Province

通过对辽宁省三道河金矿区的水文地质测绘、地质钻探和抽水试验,结合地貌和气象水文资料,基本查明了该金矿的水文地质特征。地下水主要靠大气降水补给及碧流河河水补给。按岩石的特征和地下水的赋存条件,含水层划分为基岩风化裂隙含水层(IA)、含金断裂破碎带构造裂隙脉状含水带(IB)、第四系松散冲洪积砂砾层孔隙含水层(IIA)及坡洪积、坡残积砂碎石孔隙含水层(IIB)。矿床充水水源为河水、大气降水、地下水及老窿水,充水通道为含矿破碎构造带。综合研究表明,整个矿床的水文地质条件复杂。

Based on the hydrogeological survey,geological drilling and pumping test in Sandao gold deposit of Liaoning Province,combined with geomorphology and meteorology hydrologic data,the hydrogeological characteristics of the gold deposit were basically identified.The groundwater is mainly recharged by the atmospheric precipitation and the recharge of the Biliu-river water.According to characteristics of the rock and groundwater existence,the aquifer was divided into bedrock weathering fissure aquifer（IA）,gold fracture zone tectonic fissure vein aquifer（IB）,the Quaternary alluvial gravel aquifer（IIA）and slope alluvial、slope residual sand gravel aquifer（IIB）.Deposit filling water were the river water,precipitation,groundwater and old hole water.Water channels were ore crushing tectonic belt.The comprehensive study shows that the hydrogeological conditions of the whole deposit are complex.
