The paper deals with the processing of radar images obtained by multi-pass shooting of the same area. It is proposed to use the Small Baselines Subset (SBaS) method to assess and reveal the dynamics of earth surface displacements in mining areas using vertical displacement maps. The method was tested on Cosmo-SkyMed radar data of the cities territory like Leninsk-Kuznetsky, Polysayevo and Belovo for the period from 2011 to 2014. The results of our survey, which helped to identify areas of subsidence and uplift of the earth's surface in these areas and the average rate of vertical displacement changes are adducer.
