摘要: 近年来我国能源及矿产资源需求旺盛,覆盖区找矿已成为热点,急需有针对性的新方法技术解决覆盖区勘查找矿问题。本文提出一种针对覆盖区找岩浆型铜镍矿的空—地—井协同快速找矿方法技术体系,并建立了针对隐伏岩浆型铜镍矿的深部矿产资源空—地—井协同快速有效勘查技术体系的架构及说明。该技术体系以覆盖区的地形、地质和深部矿产资源分布特点为前提条件,以综合航空地球物理为主、协同地面—井中地球物理探测方法为手段,以大数据融合、弱信息提取、地球物理-地质建模方法为重点,以地质构造和成矿理论为指导。该技术体系在新疆若羌县启鑫地区隐伏岩浆型铜镍矿床勘查中得到验证,并取得较好的应用效果。Abstract: In recent years, prospecting in coverage areas has become an important topic in China due to the strong demand for energy and mineral resources, and there is an urgent need for new targeted methods and technologies of prospecting. This study put forward a technology system for the collaborative and rapid prospecting of copper-nickel deposits in coverage areas that combines airborne-ground-borehole prospecting methods and technologies. Meanwhile, this study established the framework and description of the collaborative, rapid, and effective exploration technology system. Taking the terrain and geology of coverage areas, as well as the distribution characteristics of deep mineral resources in the area as preconditions, this technology system mainly uses the methods of aero geophysics combined with ground and borehole geophysical exploration and focuses on big data fusion, weak information extraction, and geophysical-geological modeling methods. Meanwhile, it takes geological structure and metallogenic theory as guidance. This technical system has been verified in the exploration of the concealed magmatic copper-nickel deposit in the Qixin area, Ruoqiang County, Xinjiang, achieving positive results.
