Assessment of Seismogeodynamic Activity of Mining Areas on the Basis of 3D Geoinformation Modeling

Abstract

The article deals with the creation of an information and analytical platform for assessing external causes of technogenic (man-made) accidents and for improving methods of their predication and prevention on the territories of long-term geological, mining, and engineering activities on the Southeastern (SE) Transbaikal region example — one of the key areas for mining and extraction of the strategic raw minerals in Russia. 3D modeling of active geological structures and hazardous seismogeodynamic processes on GIS-based technologies is a key instrument for forecasting dangerous natural and technogenic events and risk reduction of their occurrence. A matter of minimizing consequences of natural and technogenic disasters for such facilities of increased technological and environmental hazards as minefields, radiochemical facilities, sites for spent nuclear material disposal, dams, gas and oil pipelines, etc. has become essential. It is necessary to assess modern geodynamic territory’s activity on a unified geoinformation platform applying the newest integrated geological-geophysical researches’ methods for these objects, to select seismically active fault-fracture zones, to determine the rate and direction of surface displacement, to establish patterns of subsoil stressed-strained state natural component influence on behavior of local technogenic processes. Taking into account the specificities of geotectonic structure of mining territories, the structure of monitoring seismogeodynamic processes network on multifunctional geodynamic test sites should be developed. Observations made on test sites form the information basis for forecasting of lithosphere condition, taking decisions on rational subsurface management and providing ecological safety of the territory.

Integrated Earthquake Catalog II: The Western Sector of the Russian Arctic

“…As can be seen from Figure 1, a large number of earthquake epicenters are located in the southwestern part of the studied region on the Kola Peninsula and Karelia as well as in the northern part of the region on the shelf boundary of the Kara and Barents Seas. The peculiarity of the western sector of the AZRF is the large number of seismic events that are not tectonic earthquakes (explosions, rock bursts, and other anthropogenic events) [32][33][34].…”

Modeling the Horizontal Velocity Field of the Earth’s Crust in a Regular Grid from GNSS Measurements

“…• deterministic methods: These methods involve the physical description of a specific model for the movements of a geological process or phenomenon. These models are commonly used for modeling displacement fields during earthquakes [Lei and Loew, 2021;Okada, 1992], fault slip displacements [Aki, 1968;IAEA-TECDOC-1987Moss and Ross, 2011;Nurminen et al, 2020;Youngs et al, 2003], surface subsidence due to mining operations [Kuzmin, 2020;Mazurov, 2016;Petrov et al, 2021], and so on. • interpolation and extrapolation methods: These methods do not rely on physical representations of the environment.…”

Dynamic Activity Index for Feature Engineering of Geodynamic Data for Safe Underground Isolation of High-Level Radioactive Waste

“…The solution to urgent problems in assessing natural and man-made risks, such as searching for anomalies in geophysical fields [1][2][3], recognizing strong earthquake-prone areas [4][5][6][7][8], geodynamic zoning [9,10], etc., requires the creation of effective methods for the formalized analysis of a complex of geological and geophysical features. When analyzing the data, the features are synthesized using mathematical modeling methods [11][12][13] and may contain complex mathematical constructions. It is difficult to interpret them physically.…”
