Stress–strain behavior of Olimpiada deposit rock mass by geodetic measurements

Authors: Panzhin A.A.

The article describes the research procedure and results on the modern geodynamics and stress state of enclosing rock mass of Olimpiada deposit. The source information is the archival data of satellite surveying aimed at updating of spatial coordinates of control survey points within the National Geodetic Survey Network and within the observation station arranged in adjacent rock mass of Vostochny open pit mine. The steadiness of the survey points is estimated. The resultant conclusion states the stability of the long-term unaltered position of the main survey station of the mine within the global coordinate system ITRF2014, which allows assuming this station suitable for the further surveying. The current coordinates of the control survey points are updated in the region of the deposit, which allows determining values and directions of vectors of horizontal movements, amplitudes and behavior of strains, as well as vertical and integral displacements and strains. From the found data on movements in rock mass, the tensors of strains and the changes in tectonic stresses which induced the strains are determined. The accomplished research provided the source data on mining conditions and strain evolution patterns required for underground mine planning and design, namely, the stress–strain behavior parameters in the test mining region and the trends of modern geodynamics of rock mass.

Keywords: modern geodynamic, movements, strains, rock mass, faults, geodynamic monitoring, satellite geodesy, pit wall rock mass.
