再论刚果(金)卡莫阿-卡库拉铜矿水文地质特征及矿坑涌水量预测

Hydrogeological characteristics and prediction of the tunnel water inflow of Kamoa-Kakula copper deposit in the Democratic Republic of Congo

通过对卡莫阿-卡库拉铜矿区地表、巷道水文地质特征进行调查,比对相关水文地质报告技术资料,以及反复观察钻孔岩性含(隔)水特征等工作,初步揭示了矿区地下水含水系统补给、径流及排泄条件,提出利用罗安群R4.2组长石砂岩钻孔抽(压)水试验技术成果参数,采用有限边界条件理论公式对矿坑涌水量进行预测,以期为矿床开采设计提供更为可靠的水文地质技术参数。

According to the investigation of hydrogeological characteristics of the surface and mine tunnels in Kamoa-Kakula copper mining area,and the referrence of relevant hydrogeological report and repeated observation of water-containing(resisting)-layer in the drilling holes,it is preliminarily revealed for the mining condition of groundwater recharge,runoff and discharge in the water-bearing system of groundwater in the mining area.The paper puts forward to use the technical pumping(-pressing)parameters of R4.2 Fromation sandstone of Luoan Group in the drilling holes,to apply the finite boundary condition of theoretical formula to predict for the mine tunnel water inflow.It is hoped to be more reliable for the hydrogeological parameters in the mining design.
