Experience in application of geophysical methods in complex geodynamic diagnostics of rock massif

Abstract

When addressing the challenges of ensuring the safety of subsoil facilities and improving the quality of mined minerals there arises the need to structure the rock mass. Certain complexes of geophysical methods are used for this purpose, which composition depends on the specific mining and geological conditions. Geophysical methods are successfully used to identify zones of fracturing, karst formation as well as in landslide-prone areas. The paper reviews examples of applying various geophysical methods to determine the structure and state of rock masses, which are used at the Institute of Mining of the Ural Branch of the Russian Academy of Sciences. Brief characteristics of such methods as engineering seismic survey, spectral seismic profiling, georadar sounding, seismic microzoning, electrical tomographic studies, and radonometry are given. Conclusions are made that the use of traditional and modern geophysical methods as part of complex geodynamic investigation, developed based on the latest fundamental knowledge of the processes that take place in the geological environment, allows reliable determination of the structural-geodynamic model of the rock mass to ensure the safety of subsoil facilities.
