We present the results of a pilot project to assess ground displacements in the Leninsk-Kuznetsky area obtained from SAR images from the new Sentinel-1C satellite in the fall of 2025. Overall, displacement areas were detected throughout the whole study region. More than 40 areas were identified where subsidence exceeded 5 cm over 72 days. During a relatively short subsidence monitoring period, displacements in some troughs in the fall of 2025 reached 30 cm over 72 days. The displacements recorded over a 72-day interval were relatively small, but regular monitoring is necessary to assess the danger of such subsidence and the dynamics of its further development. The results presented in this paper demonstrate the effectiveness of SAR interferometry methods for identifying areas of ground subsidence in the Kuznetsk coal basin. The commencement of Sentinel-1C satellite surveys over vast areas opens up opportunities for regular monitoring during the snow-free period that usually lasts from late April to early November in Kuzbass. Longer-term monitoring will enable tracking the movement of ground motion troughs and promptly detecting their approach to significant infrastructure assets, such as roads, villages, industrial facilities, and residential buildings, as well as monitor acceleration of displacement speed and promptly identify areas of potential collapse. Ground displacement data are also used to calibrate numerical models of the stress-strain state of underworked rock masses, enabling forecasting stress-strain state evolution depending on future mining plans.
