摘要
通过对冬瓜山铜矿大团山矿床深部(-730m~-1000m),36A~43线水文地质特征及成因分析,研究表明:本矿床主要矿体位于当地侵蚀基准面以下,地形有利降水排泄,地表水不构成矿床的主要充水因素。矿床地下水主要赋存在-200m以上,岩溶裂隙含水,主要含水层为三叠系碳酸盐岩,富水程度中等~弱。矿床地下水靠降水补给,深层地下水局部接受上部越流和轴向深层地下径流的补给。
Through the analysis of the hydrogeological characteristics and genesis of the deep(-730m~-1000m)and 36A~43 lines of the Datuanshan copper deposit in Dongguashan,the study shows that the main ore body of this deposit is located below the local erosion benchmark,and the terrain is favorable for precipitation discharge.Surface water does not constitute the main water filling factor of the deposit.The underground water of the deposit mainly exists at a depth of-200 meters or more,with karst fissures containing water.The main aquifer is the Triassic carbonate rock,with a moderate to weak degree of water abundance.The groundwater in the ore deposit is replenished by precipitation,and the deep groundwater locally receives recharge from upper overflow and axial deep groundwater runoff.
