| In 2006, he graduated from the Geological Faculty of Lomonosov Moscow State University. From 2009 to the present, he has been a lecturer in the Department of Seismometry and Geoacoustics at the Geological Faculty of Lomonosov Moscow State University. From 2014 to the present, he has been engaged in entrepreneurial activity providing geophysical research services. PhD in Physics and Mathematics His area of interest is seismic exploration. He is currently developing mid-depth seismic exploration (to depths of 500-1000 m), including for applications related to solid minerals. |
Construction of a detailed 3D model of tectonic faults based on 3D seismic exploration data
Tectonic faults significantly impact mine construction and underground mining. Tectonic fault zones are characterized by increased fracturing and weakened rock strength, which reduces rock mass stability, leads to deformation and collapse, and necessitates enhanced mine support measures. Faults often serve as migration pathways for groundwater and gases (primarily methane), leading to water influxes, gas-dynamic manifestations, and explosive and fire hazards. Furthermore, tectonic structures are difficult to study using drilling methods—at best, only individual, major faults can be traced, but a detailed picture is revealed directly during mine development, which does not always allow for timely implementation of appropriate measures. This report demonstrates the authors' experience in using ground-based 3D seismic reflection surveys to construct a detailed 3D model of tectonic faults at a mine site. The resulting volumetric model of tectonic faults can be used at various stages of solid mineral development, from mine design to planning degassing, dewatering, or early injection of fault zones. This will reduce unexpected costs for emergency response and significantly improve mining safety.
