The report presents an analysis of the earth’s surface subsidence and depression at Stebnyk potassium salt deposit for the period from 2003 to 2019. Possible causes of subsidence, including deformational, hydrogeological, and mining ones, have been identified. The report also indicates how it was possible to eliminate the undesirable consequences of raw material extraction in the post-exploitation period.
The regime topographic and geodetic observations of the earth’s surface subsidence along reference profiles in the mining area have been analyzed. Spatial modelling of the earth’s surface subsidence has been carried out and practical changes in deformation dynamics have been determined. The high efficiency of geodetic observations has been proven and the main factors that cause a sharp degree of the earth’s surface subsidence and depression have been established. The real mould of subsidence and significant depressions, which pose a threat to agricultural land use and industrial facilities operation, have been indicated.
