Underground hard coal mining causes surface deformations. When the mining operations are conducted beneath linear objects, such as motorways, there is a risk of deformations of the axis of the road and its horizontal and vertical alignment (additional bends and vertical curvatures, longitudinal inclinations, deformations of cross-sections). In the areas subjected to mining operations, mining plants conduct geodetic monitoring. Due to their labour intensity and costs, geodetic measurements are usually made only a few times a year. The article discusses the possibility of applying Interferometric Synthetic Aperture Radar (InSAR) to monitor the subsidence of the vertical alignment of motorways caused by mining operations and its advantages and disadvantages compared to the currently used methods of geodetic measurements. The tests were conducted in two sections of motorways within the Upper Silesian Coal Basin (Poland) in the areas of intensive hard coal mining operations. Radar imaging of the surface made by the European Space Agency's (ESA) satellite Sentinel-1 equipped with the Synthetic Aperture Radar (SAR) was used.

W artykule przedstawiono przykłady trzech obiektów mostowych: mostu drogowego, mostu kolejowego oraz wiaduktu kolejowego, w których zastosowano nietypowe zabezpieczenia przed wpływami eksploatacji górniczej. Opisano schematy statyczne zastosowanych układów oraz zasady pracy poszczególnych elementów zabezpieczeń konstrukcji. Omówiono wady i zalety takich rozwiązań.

The paper presents examples of three bridge structures: a road bridge, a railway bridge and a railway viaduct, in which atypical protections for mining exploitation were used. Static diagrams of the systems used and the principles of operation of individual structural protection elements were described. The pros and cons of such solutions were discussed.
