摘　　要：非洲国家矿产资源丰富,国内越来越多的地勘单位在非洲国家开展境外矿产资源勘查项目。然而对技术人员来说,每一个项目在实施前,都要充分收集项目实施所必须的地形图等相关基础测量资料,弄清楚项目实施区域内已有测量基础资料的坐标系统、椭球类型、高程系统及投影方式十分重要。但是,不同国家和地区所使用的椭球及投影系统等不尽相同,这样会给技术人员带来困惑。因此,本文结合近几年在非洲国家开展工作的经验,对非洲国家坐标系统的类型进行了详细分析,并且结合相关地质调查实践进行介绍,为我国地质工作人员在非洲国家开展地质工作提供一些参考,以起到抛砖引玉的效果。Africa countries rich in mineral resources, more and more China geological prospecting units develop mineral re- sources exploration projects in Africa. However, the technical personnel, each project must fully collect related basic to pography ineasurement data for project before entering the trade, and making sure coordinate system, ellipsoid type, elevation system, projection method of existing measurement data within the projection area is very important. However, el- lipsoid and projection system of different countries and regions are different, this will give the technicians confusion. Therefore, this paper based on working in the last few years in Africa countries, analyzed coordinate system types of Africa countries in detail, and combined with the related geological survey practice to introduce, providing some reference for China＇s geological work personnel to carry out geological work in Africa, in orde to play good effect.
