刚果(金)KOLWEZI铜(钴)矿三维地质模型及找矿方向

Three dimensional geological model and prospecting direction of KOLWEZI copper(cobalt)deposit in the Democratic Republic of Congo

刚果金KOLWEZI铜(钴)矿位于加丹加铜钴成矿带上,矿床以铜矿为主,伴生钴矿,主要赋存在罗安群矿山亚群(R2)中,以层状矿体为主,明显受地层及构造控制;本文利用Surpac软件在详细研究矿区构造、地层和矿体特征的基础上建立地质模型,圈定了38个工业矿体,并使用距离幂次反比法(Inverse Distance Method)进行资源储量估算;经研究矿区东部致-1200线矿体为封闭找矿潜力巨大,矿区RAT紫红色砂岩下部是否有其他含矿层位有待探索。

The KOLWEZI copper(cobalt)deposit in the Democratic Republic of Congo is located on the Katanga copper cobalt mineralization belt.The deposit is mainly composed of copper,accompanied by cobalt deposits,and mainly occurs in the Ron Group mining subgroup(R2).It is mainly composed of layered ore bodies and is clearly controlled by strata and structures;This article uses Surpac software to establish a geological model based on a detailed study of the structure,strata,and ore body characteristics of the mining area,delineates 38 industrial ore bodies,and uses the Inverse Distance Method to estimate resource reserves;After research,the ore body of the Zhi-1200 line in the eastern part of the mining area has great potential for closed exploration.It remains to be explored whether there are other ore bearing layers in the lower part of the RAT purple red sandstone in the mining area.
