    基于数字矿床模型的西藏玉龙斑岩型铜矿三维定位定量预测

    3D positioning and quantitative prediction of Yulong porphyry copper deposit, Tibet, China based on digital mineral deposit model

    • 摘要: 西藏玉龙铜矿是世界级的超大型斑岩型铜矿,位于迄今中国发现的最大的斑岩型铜矿带上。目前对于这一令人瞩目的铜矿区的研究大多建立在二维的基础上。鉴于此,以“数字矿床”技术为手段,结合西藏玉龙矿区的地质特征,以Micromine 软件作为平台,选择合适的建模方法,构建起玉龙斑岩型铜矿区的数字矿床模型,开展资源的三维定位定量预测。研究表明,西藏玉龙铜矿Ⅰ号矿体体积大、品位低、资源量最多,外围的Ⅱ号和Ⅴ号矿体由于次生氧化,体积小而品位高,具有可观的富矿资源和优先开采的价值。对实例的研究也表明,基于数字矿床模型的研究方法在现代的矿产资源开发中具有明显的优势,有着较高的推广和应用价值。

       

      Abstract: Tibet Yulong copper deposit is a super porphyry copper in the world, also is part of the largest copper metallogenic belt proved so far in China. Currently, the research of this remarkable copper deposit is based on Two-dimensional. In view of this, this paper built the digital mineral deposit model of Tibet Yulong copper deposit, based on the geological features of this copper deposit, by the popular "Digital Mineral Deposit" method based on the software of Micromine, and made research on the 3D positioning and quantitative prediction of the resource. Studies have shown that the No.1 orebody of Tibet Yulong copper deposit is large and have most low-grade resource; the No.2 and No.5 orebody in the peripheral have small size and high-quality as a result of secondary oxidation, and they are rich with significant resource and they should have the priority to be mined. This study also demonstrates the obvious advantage of the study based on the digital mineral deposit model in the modern development of mineral resources, and this method has a higher value of the promotion and application.
