吉林省龙井市石井金银矿矿区水文地质条件评价

Hydrogeology conditions evaluation of Shijing gold-silver mining area of Longjing City,Jilin Province

吉林省龙井市石井金银矿位于长白山系老爷岭南麓的丘陵地貌中,区内地下水的形成、分布、埋藏条件严格受地质构造、岩性、地貌等条件控制,地下水的补给来源为大气降水。矿区含水层主要类型为:第四系砂砾石孔隙潜水含水层、基岩风化构造裂隙水含水层、构造裂隙脉状水含水层(带);三种地下类型水富水性都较小,对矿床影响不大,该矿区水文地质条件属简单类型。

Jilin Longjing Shijing gold-silver mine is located in southern foot of Laoyeling hilly landform of Changbai Mountain.The formation,distribution and burial conditions of groundwater are strictly controlled by geologic structure,lithology,landform conditions,groundwater recharge sources is the atmospheric precipitation.The main types of aquifer in the mining area is：sand and gravel pore phreatic aquifer of the Quaternary System,bedrock weathering fissure water aquifer,Structural fissure vein water aquifer（zone）.Water abundance of three types underground water are small,have little impact.Hydrogeologic condition in the mining area is simple type.
