In focus is the effect of deformation processes running in rock masses on safety and functional reliability of subsoil use objects. The technology of identifying hazardous areas in boundary zones of secondary structural blocks formed under influence of the modern geodynamic movements is developed. The substantiated technology for the diagnosis of geodynamic activity in geological media, selection of favorable locations for underground mine objects and estimation of their safety includes the analysis of stress-strain state of adjacent rock mass using the satellite geodesy techniques and theoretical constructs. Parameters of large and medium spacings to measure spatial and time variations in natural and induced stress state of rocks are determined. Based on the changes in the spatial coordinates of check points, two types of the modern geodynamic movement are studied – trend and cyclic. The article reports the results of geodetic surveying of pitwall rock mass at Zhitikara open pit asbestos mine. The variation in the integral stress–strain state in the open pit and the adjacent area is examined, and the mosaic–discrete behavior of straining is identified. The method is proposed to determine parameters of initial tectonic stress field towards qualitative and quantitative geomechanical modeling of pitwall stability. The technology is used to ensure operational safety of mines. The research findings are analyzed, and ways to enhance the technology efficiency are offered.
