中国西部铜矿资源勘查开发现状和潜力及接替区选区

Study of exploration and development potential of copper deposits and selection of main copper resources succeeding areas in western China

新世纪以来,中国西部地区的重要成矿区(带)内探明了一批大、中型铜矿床,致其铜矿资源储量和产能大幅度增长,已形成了东西并驾齐驱的铜矿勘查开发格局。文章简要介绍了新世纪以来西部地区探明的主要大型铜矿床的地质特征。通过综合评价,优选出14个西部铜矿资源接替区,即在未来的5至10年间可实现规模开发的中观尺度的资源接替基地。预期到"十三五"末,通过加大勘查开发力度,西部铜矿接替区的铜产能和资源储量都将显著增加。西部铜矿接替区大多地处高山深谷区或荒漠戈壁区,开发基础条件落后,生态环境脆弱,应加快其基础设施的建设,同时,应做好铜矿资源开发的环境影响评价与规划。

Since the beginning of the 21st century, a number of large and medium-sized copper deposits have been proved in some important metallogenic belts, and the copper resources and reserves as well as production capacities have been increasing remarkably in western China. The copper exploration and development of western China have kept pace with or even exceeded the exploration and development speed of central and eastern China. This paper briefly describes the geological characteristics of the major large copper deposits proven since the beginning of the new century in western China. From multiple sector assessment, 14 main copper resources succeeding areas, or intermediate-scale resource succeeding bases were selected, in which large-scale copper resources development can be implemented in the next 5~10 years. It is expected that the copper production capacity and copper resources reserves will substantially increase by the end of the 13th Five-Year-Plan through enhancing exploration and development in these western main copper resources succeeding areas. However, most western China＇s copper resources succeeding areas are located in high relief mountainous areas or Gobi desert areas, the basic conditions for development are rather backward, and the ecological environments of these areas are very fragile. The development of infrastructure should be accelerated and the environmental impact assessment planning should be prepared before the large-scale development of copper resources.
