Abstract
The authors present the procedure and data of many years-long geodynamic monitoring of the ground surface displacements in Uzelga and Talgan mining areas. Despite similar geological conditions, the difference in the types of the protected objects on the ground surface conditions different variants of the procedure for each deposit. Some points of reference surveying network and observation plugs are re-fixed using the satellite data, digital elevation meter and electronic tachometer, and characteristics of trends in modern geodynamic movement induced by a displacement trough are obtained. The results of the implemented geodynamic activity assessment include vectors of general spatial displacements of observation plugs and curves of compression-tensions and shearing strains. It is determined that rock mass deformation has a discrete mosaic pattern. The conclusions are generalized, and the hypotheses are made on the further deformation of the ground surface.
