The flooding of the Mirgalimsay Mine in the 1990s triggered the activation of hazardous geological processes in the adjacent area, including the city of Kentau. Subsidence, sinkholes and alterations in the hydrogeological regime are observed, posing significant risks to people and infrastructure. Consequently, monitoring of ground surface deformations using modern remote sensing techniques, such as Interferometric Synthetic Aperture Radar (InSAR), has become particularly relevant. This paper presents an integrated monitoring methodology based on InSAR, including Persistent Scatterer Interferometry (PSI) and Small Baseline Subset (SBAS) techniques, which enables assessment of vertical displacements with millimeter-level accuracy while minimizing the impact of atmospheric and orbital errors. Using Kentau as a case study, we demonstrate that this approach effectively identifies zones of intensive subsidence (up to 25 mm/year), validates data through ground-based measurements, and provides recommendations for ongoing monitoring and risk mitigation.
