Integrated Multi-Level Geomonitoring of Natural-and-Technical Objects in the Mining Industry

Abstract

The system of integrated multi-level geomonitoring is developed for technical objects and oil/gas reservoirs in the west of Russian Arctic. The system is based on the principle of synchronization of inter-branch researches, including geodetic, geomechanical, geophysical and geotechnical measurements on the ground surface and by GPS, as well as subsurface, surface, aerial and GPR survey. The system uses the information technologies Big Data and Cloud Service with intelligence elements, and provides geomonitoring investigations at differ levels: remote, air, surface, subsurface, computer. In-situ inter-branch multi-level studies are the framework of the geomonitoring which continuously replenish and updates data bases. The multi-level approach is also involved in computer modeling: the geodynamic models of a manmade object, Kola Peninsula, Baltic Shield and Eurasian Plate are created as hierarchically nested structures. The models are analyzed under various boundary conditions, which enabled solution of an inverse problem on stress state of subsurface rock mass differentially by the investigates scales. The multi-level geomonitoring system is implemented at technical objects of the key mining companies of the Kola Peninsula: Kovdorsky GOK, Kola MMC, Apatit, Oleniy Ruchey and OLKON GOKs.
