Observations of building structures in mining areas, reveal the occurrence of periodic and permanent excessive loading situations. These include ground deformations associated with the extraction of underground mineral deposits. In urban areas, these deformations significantly alter the operating conditions of building structures. For this reason,...

... measurements in 2022 − 2024 will be within the range of the main influences from the mining of the parcels directly below them. The structures of the buildings will be subjected to dynamic impactsfrom the full passage of the extraction front -and to fixed impacts -once the extraction is fully completed. Fig. 1 shows a map of the study area and Fig. 2 shows the location of sections of the mining plots of seams 703 and 713 in relation to the buildings included in the measurements. The testing ground structures will be in different mining situations during the measurement observation period, thanks to which the states of deformation of the structure corresponding to the influence ...

... Obiektów Antropogenicznych 4 (2023) 11-25 -21 - Figures 10 and 11 display the variations in tilt on the sensor axes. Using the measurement results, it is possible to analyse the spatial behaviour of the closed-section masonry structure, which was subjected to mining activities in seams 703/1-2 and 713/1-2 from March 2021 to September 2022 (see Fig. ...

... of the tower structure to variable tilting of the underlying mass. Analysis of the mining activities indicates that since the start of mining in this area, the tower has been located on the convex edge, at the junction of two depressions located outside the object, resulting from the exploitation of parcels in an orthogonal arrangement (see Fig. ...
