REMOTE SENSING APPLIED IN MINING SECTOR
We will discuss in this paper about how remote sensing methods are used in mining domains, doing reference at minerals, geology, soil, topography, land cover and vegetation, water and groundwater and mine contamination. There are a lot of methods used for exploration are airborne and ground based geophysical methods, such as magnetic, electromagnetic, gravity, radiometric and seismic investigations to map the subsurface geology; multispectral and hyperspectral airborne and satellite remote sensing can provide valuable information about the surface mineralogy and geology. Detailed knowledge of the surface topography or the change in surface topography is important in several aspects of the mining sector. Mapping and monitoring of vegetation around mine sites is important in all phases of mining, from mine planning to mine closure and rehabilitation. Vegetation maps are often required. Knowledge of surface and ground water pathways is also important in and around mining areas. Ground water can to some extent be mapped with optical remote sensing techniques. A common type of contamination caused by mining is acid rock drainage
