摘要:
稀有金属的战略地位使得对稀有矿山的监测具有至关重要的意义.以江西宜春414特大型钽铌锂稀有金属矿床为例,利用ZY-3号国产卫星、IKONOS及WorldView2卫星等多源遥感数据,建立矿山典型地物的遥感解译标志;结合矿权信息和地质岩体信息,分析评价稀有矿山的开发利用现状;并根据稀有矿山与高岭土矿山纹理信息的差异,进一步区分了同一岩体中的2种矿床类型;最后,基于ZY-3号卫星数据建立的三维图像,对该矿山存在的地质滑坡问题进行了评估,并对3种高分遥感数据在稀有矿山监测中的应用效果进行了对比分析.研究表明,高分遥感数据的处理与分析为稀有矿山开发现状及矿山环境监测提供了良好的技术手段,有进一步推广应用的价值.
Abstract:
The investigation of rare metal mine is very important due to its strategic position in recent years.In this paper, the investigation of the No.414 superlarge rare metal mine (tantalum, niobium, lithium) in Yichun of Jiangxi Province was conducted using the satellite remote sensing data of ZY-3, IKONOS and Worldview-2.Firstly, the interpretation keys of each feature in the mine were built, and the mining situation was delineated with the help of the mining right data and geological rock data.Then, the difference between rare metal mining and kaolinite mining was studied using texture information on the image.Finally, the landslide of the mine was estimated using the three-dimensional representation of the ZY-3 satellite data, and the application comparison of the three kinds of satellite data was analyzed.The results show that high resolution remote sensing processing can provide a good method for quick and accurate mining status investigation and geological environmental analysis of rare metal mines,thus having further popularization and application value.
