“…Additional benchmarks are also sometimes located on building structures that require special monitoring. Nowadays, modern satellite measurement technologies (GNNS) and photogrammetric/interferometric methods (terrestrial laser scanning, aerial scanning, radar interferometry) are used (in addition to the so-called conventional ones) for monitoring mining sites [4][5][6][7][8] The above measurement technologies can also be used to monitor changes and deformations of building masses. However, observations of this type are characterised by periodicity, resulting from the frequency of raids or the execution of a measurement session.…”

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, forecasts of ground transformation and analyses of possible changes in the technical condition of buildings on the ground surface are made in advance, even before mining is commenced. Taking into account previous in-house experience of the observed effects of mining impacts on building structures, an original method of monitoring changes in the condition of these structures has been developed. The aim of the monitoring is to record phenomena that change the operating conditions of the structures. In the developed method, measurements are made quasi-continuously using strain and deflection sensors mounted directly on structural elements. In the mining area affected by the mining operation being carried out in the years 2020 - 2022, and with a further one planned in the years 2023 - 2024, through the extraction of 14 coal parcels, three public utilities of special interest were monitored. The measurement results of deformation changes in the elements allow for an assessment of changes in the stress state of the structures, and the integration of sensors mounted on the structures into a wireless network fulfils the demands for maintaining public safety conditions in mining areas. It also contributes to the analysis of fatigue issues in masonry structures due to long-term multidirectional loads.

This research aims to explore the potential of image metrology as a substitute for monitoring building structural deformations. It utilizes stereo-photogrammetry and the Kalman filter in its approach. The ultimate goal is to reduce the damage to human lives and property caused by the collapse of building structures in urban areas. Image metrology and conventional geodetic surveying were both used in monitoring the deformation of a selected building prone to land subsidence. Four geodetic monitoring stations were established using the GNSS surveying technique, while 10 photo points were placed on the selected building for deformation monitoring. Simultaneous observation of photo points and acquisition of their images were carried out during the first three months of this study. The data acquired via geodetic survey were subjected to least square adjustment while the images acquired were subjected to stereo-photogrammetry and Kalman filtering for extraction and refinement of photo point coordinates. The preliminary results show that image metrology is comparable to conventional geodetic survey methods for monitoring building deformation down to 100 mm. The t statistic value of 1.524234 and t critical value of 1.7291333 justify the comparability.
