IDENTIFICATION OF GEODYNAMIC HAZARD CONTROL FACTORS IN TERMS OF 3D GEOLOGICAL-STRUCTURAL MODEL OF THE NATURAL-TECHNICAL RASVUMCHORR MINE–TSENTRALNY OPEN PIT SYSTEM IN KHIBINY

Download
The geodynamic safety represents one of the most essential factors of mining operations, which is especially actual for the environmental and technical systems (ETS) with accumulated large-scale human-caused transformations of the parental geological setting. In order to investigate the ETS geodynamics, various remote instrumental in-situ analytical and monitoring methods setting identification, zoning and ranking of all geodynamic hazards as the final target, are applied. This paper reports the results of comprehensive geological, structural, and tectonophysical surveys in the «Rasvumchorrsky Mine – Central Open Pit ETS» (Khibiny), which led to the identification, geometrization, and 3D-vizualization of main factors controlling the geodynamic hazard in the ETS under discussion. It is concluded that the man-induced (anthropogenic) factor dominates in this site of bowels.

The studies have been conducted in the framework of R&D No. 0231–20150013 (heads—D.V. Zhirovi, V.V. Rybin) under management and support from Apatit Company and Mining University. The acquisition, processing and analysis of data on stress fields has been supported by the Russian Science Foundation, Grant No. 14–1700751 (research manager—Professor, Doctor of Engineering Sciences A.A. Kozyrev). The authors express their deep gratitude to the management and staff of Apatit Company for the organization and tech support. Separate thanks go out to P.A. Korchak, P.L. Glazunov, A.A. Streshnev and S.V. Tsirel.

Keywords
