Abstract
Summary
Radar research is an area of remote sensing of the Earth, which has been successfully used recently, including monitoring the earth’s surface in mining and post-mining areas. The territory of Solotvyno, the emergence and development of which is associated with salt extraction, differs in the development of natural and man-made hazardous geological processes, which in recent decades have become uncontrolled. Analysis of satellite images interpretation results was carried out in order to establish the basic patterns of surface deformations (earth’s surface vertical displacements frequency and scale), assess the intensity of hazardous geological processes manifestations and their impact on critical infrastructure objects, areas of enhanced vulnerability and/or uncertainty of risks. Using the results of satellite radar monitoring, the assessment of natural-technogenic hazardous geological processes of Solotvyno area in 2016–2020 was done. The assessment of the control objects vertical displacements was performed using interferometric processing of satellite radar monitoring data with the ENVI software SARScape module by applying multi-pass radar interferometry technologies (SBAS and PS approaches). As the result of monitoring, the new data were obtained on the parameters of hazardous natural-technogenic processes manifestations in Solotvyno, their impact on critical infrastructure objects was assessed, zonation and risk scheme were improved.
