位于江西省德兴市境内的江西铜业公司德兴铜矿，早在唐宋年间就有开采历史。新中国成立后，先后进行了两次勘探，探明矿石储量11．3亿t。从1958年建矿开始，走外延扩大生产和内涵技术改造并举的路子，分一、二、三期建设：一期工程于1965年建成2500t／d生产规模井下矿，后逐步 Dexing Copper Mine, a Jiangxi copper company located in Dexing, Jiangxi province, had a mining history as early as the Tang and Song dynasties. After the founding of New China, it carried out two explorations, with proven reserves of 1.13 billion tons of ore. Starting from the 1958 mine construction, we have taken the road of epitaxial expansion of production and the connotation of technological transformation. We have constructed the first, second and third phases. The first phase of the project was completed in 1965 with the production of 2500t/d production-scale underground mines.
