The purpose of the system concerns data management and data analysis for the support of studies of surface behaviour in the area of the Walbrzych part of the Lower Silesia Coal Basin. The process of developing, with the use of ArcObjects environment, an application facilitating selected procedures of data exploration and spatial analyses, in the system, based on the Map Algebra principles has been discussed. The functionality of analytical tools has been demonstrated on the example of analyses of mining activity carried out in the “Barbara” coal field of the “Victoria” mine. These include: exploration and selection of coal parcels according to the given criteria (depth below surface, slope), calculation of mining conditions of coal parcels and progress of underground mining operation in time. In the article a concise review of geographical information systems use in studies of the state of grounds under the influence of mining activity presented in national and international literature has also been given. %A Blachowski, Jan %A Stefaniak, Paweł %P 5-21 %R 10.5277/gig121801 %U https://doi.org/10.5277/gig121801
