摘要
以刚果(金)SICOMINES铜钴矿为背景,通过分析矿区水文地质条件、矿区1976—2022年地下水流场演变特征和排水数据,对矿区水位变化规律进行深入研究,结果表明地下水动态变化特征是以侧向补给为主、降水为辅;排水以补给量为主、储存量为辅。地下水流动以管道流为主、渗流为辅,含水层之间联系密切,地下水渗透阻力小,坡度缓,连通性好,下部含水层排水能降低不同含水层水位。地下水系统主要由缝、洞构成,存在以空洞为汇集的地下水主径流带,矿区为构造控水。
The SICOMINES copper cobalt mine in Congo(Kinshasa) was selected as research background. Through analyzing the hydrogeological conditions of the mining area, the evolution characteristics of groundwater flow field and drainage data from 1976 to 2022, the law of water level variety were studied in depth. The results indicate that the dynamic variation characteristics of groundwater were mainly dominated by lateral recharge, followed by precipitation, and Drainage is mainly dominated by supply, followed by storage. The groundwater flow is dominated by pipeline flow and supplemented by seepage, close connection between aquifers, low groundwater seepage resistance, gentle slope, good connectivity, and the drainage of the lower aquifer can reduce the water level of different aquifers. The groundwater system is mainly composed of fractures and caves, and the main groundwater runoff zone is collected by cavities, groundwater is controlled by geological structure.
