| 摘 要： | 阳山金矿床为一尚未开发的特大型金矿床。矿区地下水类型有第四系孔隙水、基岩裂隙水和构造带脉状裂隙水等三类。第四系松散堆积物及地表浅部节理裂隙发育的基岩为区内含水层，深部节理裂隙不发育的千枚岩、灰岩及斜长花岗斑岩为矿区隔水层。矿区西侧马连河水水质较好，可作为矿山开发用水源地。矿山开采过程中，第四系松散覆盖层的厚度、地下水对矿区有害元素的溶解程度以及地表水、地下水的二次污染等，均为矿山开发时应该研究的水文地质和环境地质问题。

| Abstract: | Yangshan Au deposit is an unexploited giant deposit. U nderground water consists of Quaternary pore water, bedrock fissure water and ve in fissure water in structure zones. Aquifers are composed of Quaternary loose d eposits and fissure-developing bedrock and aquifuges consist of deep fissure-und eveloped phyllite, limestone and plagiogranite porphyry. The Malian River water has good water quality and may be used as industrial water and drinking supply. Thickness of the Quaternary loose deposits, dissolubility of harmful impurities, secondary pollution of surface water and underground water during exploitation should be studied. |
