遥感技术在斑岩铜矿勘查中的应用

斑岩型铜矿的勘探对于国民经济的发展有着重要的意义,遥感技术以其自身优势在斑岩铜矿的找矿工作中起到了重要的推动作用,但以往的工作多注重于某种遥感技术或几种技术组合在斑岩铜矿勘查中的应用，而对各类技术的综合运用与评价尚显不足。介绍了遥感技术在斑岩型铜矿床勘查中的应用历史、现状及几种常用技术，如反射光谱技术、多光谱遥感技术、高光谱遥感技术、雷达技术，并详细介绍这些技术的核心方法、主要应用方向及成功实例。最后对这些技术进行对比分析，指出了每种技术的优缺点，结合各自的特征，介绍了几种技术方法组合，并通过成功实例证明其应用的科学性，尤其适合大面积的勘查扫面工作。

Application of remote sensing in porphyry copper exploration

The exploration of porphyry copper deposits is of great significance to the development of national economy. Remote sensing has played an important role in promoting the prospecting of porphyry copper deposits by virtue of its advantages. Previous studies considered the application of some remote sensing techniques or combinations of several technologies in the exploration of porphyry copper deposits, but there was a lack of comprehensive application and evaluation of various technologies. This paper introduced the history and current situation of the remote sensing application in the porphyry copper deposit and several commonly used techniques such as reflectance spectroscopy, multispectral remote sensing, hyper-spectral remote sensing and radar technology, detailed the core methods, application direction of these technologies and successful examples. Finally, these technologies were compared and analyzed, and the advantages and disadvantages of each technique were pointed out. In view of their respective characteristics, some technical combinations were introduced, and their scientific and practical results were proved by successful examples. The utility model is especially suitable for the large-scale survey and scanning.
