| 摘 要： | 阳山金矿床第四纪黄土及残坡积层出露较广，厚度大。矿区地下水类型主要为孔隙与裂隙潜水，分布于坡地及沟谷两侧，主要补给来源为大气降水的垂直渗入，以山泉及溪流形式排泄，含水层为第四纪松散堆积及岩石风化层，隔水层为地表深部的基岩，矿床水文地质条件简单。马连河为矿山开发用水源地。依据地层岩性、岩石力学性质划分为第四纪松散软弱岩类，碎裂岩、千枚岩、斜长花岗斑岩等裂隙发育带及构造破碎带软弱岩类，灰岩及深部脉岩、钙泥质千枚岩等块状岩类工程地质岩组，矿床工程地质条件中等。

| Abstract: | Loess and eluvium of Quaternary are thick and spread widely in the Yangshan gold mining areas.In the hillside fields and two flanks of gullies,the type of ground water is mainly pore water and fissure water,which recharged predominately by vertical infiltration of meteorological water and drainaged by hill springs and brooks.Aquifer consists of loose deposit of Quaternary and weathering rock;aquifuge is the bedrock in the depth of the surface. The hydrogeological condition of the deposit is simple,and water for mine development comes from Malian river.According to lithologic character and rock mechanics property,different engineering rocks have been divided, such as Quaternary loose soil, cataclastic rocks,phyllite,plagiogranite and so on into soft rocks in the well-developed fissure zone and structural weak zone.Limestone,dike rocks in depth,and calcareous politic phyllite and so on belong to blocky engineering geological petrofabrics.Engineering geological conditions in the mining areas are medium. |
