Abstract
The article presents the ground surface deformation monitoring data for a 40 years-long period. The space and time parameters of geodynamic movements are revealed from the analysis of long-term observation over ground movements. The ground movement data base is created for the classification, modeling and estimation of ground movements, and for the analytical definition of patterns in big data arrays. The statistical and wavelet analyses of rates of change in vertical displacements of ground surface are performed. The ground surface zoning is carried out at the Sarany chromite deposits and in the adjacent areas with a town and industrial facilities. The results are useful for the detection of unknown parameters of geodynamic processes on ground surface, and for the prevention of accidents connected with instability of capital facilities during underground mining.
