Аннотация
At the Khandiza polymetallic deposit located in the Sariosiyo district of Surkhandarya region, underground mining activities may lead to deformation of the earth’s surface. The geological complexity of the rock mass and the intensity of mining operations cause uneven spatial and temporal development of subsidence processes. In this study, InSAR technology based on Sentinel-1 satellite radar imagery with revisit periods of 7 and 18 days was applied. To minimize the effect of temporal decorrelation and enhance the detectable deformation gradient, SBAS (Small Baseline Subsets) and IPTA (Interferometric Point Target Analysis) algorithms were integrated. As a result of data processing, a spatially continuous deformation model of the deposit area was generated, and subsidence rates of up to several tens of centimeters per year were identified in actively mined zones. The analysis showed that the intensity and spatial distribution of deformations are closely related to mining depth, ore body thickness, and the system of tectonic faults.The monitoring results are of significant importance for assessing the stability of mining infrastructure, protecting surface structures, and ensuring industrial safety. The obtained data provide a scientific basis for remote monitoring of geodynamic processes and for improving environmental management at the Khandiza deposit.
