ABSTRACT
The area of the Upper Silesia Coal Basin (USCB) was in the past and still is under the influence of underground coal mining. The consequence of the occurrence of impacts of mining operations on the surface is the disturbance of water circulation system and conditions of ground-water environment. The effects of mining operations on the surface of mining areas include inundations and post-mining overflow lands. In recent years (mid-80s and 90s of the twentieth century), single analysis of the level of water accumulation on the surface as well as comparative analysis of changes were carried out in the Central Mining Institute. The information collected at that time about overflow lands was based on data concerning the surface, depth, volume and quality of water, type of the overflow land, ground conditions, etc. obtained from mines within USCB. The possibilities of data analysis, their supplementation and spatial processing were significantly limited at that time compared to the current methods of acquisition, processing and visualization of data. At present, the measurements can be taken using satellite imaging or laser scanning and subsequently, data can be stored in GIS spatial databases and be subject to further (multidimensional 3D, 4D) spatial analysis and interpretation. In recent years, remote sensing technique of Earth surface becomes more and more attractive due to the increasing precision of devices used for registration of electromagnetic radiation (sensors) and the possibilities of their use. The sensors are installed mostly on boards of satellites that orbit the Earth. Additional factors which increase the attractiveness of satellite imaging include launching new satellite systems into orbit, which have better and better spatial, spectral and temporal resolution as well as miniaturization of such devices, which is reflected in the costs related to launching such a system into orbit. A distinguished factor is the trend of lowering the purchase prices of these imaging, compared with the purchase price some years ago which is also the result of making this technology more popular and cheaper. The author included in this paper information from literature which was also analyzed in terms of the practical use of satellite imaging in mining and environmental hydrogeology, as a modern source of obtaining data for hydrogeological analysis. After the analysis of information on remote sensing techniques means used for observation of water accumulation on the surface of areas under influence of mining operations, the author points out the types of satellite imaging which can be used for mapping the water conditions on the surface and within the subsurface area of overlay formations of deposit beds.
