Geophysical research of the rock massif in underground mine conditions

Geophysical methods of research of rock mass are one of the most effective ways of solving various problems in mining and are widely used in mining, gas and oil industry, as well as in science. They allow remote search and assessment works, detection of structural inhomogeneities, voids, contact zones of various media in the rock mass with sufficient high accuracy. The article presents research and comparative analysis of geophysical methods of geophysical sensing and spectral seismo-profiling in underground mine conditions with determination of permissible tasks for which these methods are capable. In complex geophysical studies, methods of spectral seismo-profiling and geo-radar sensing in underground mine conditions have been applied. Measurements were made to search for different objects and at different angles to the object being searched. The use of geophysical methods made it possible to detect the metal shelf under the bulked rock mass with the separation of the boundaries of two tiers of the shelf during vertical measurements. In the process of searching for the underlying excavation in the mass during vertical geophysical measurements, which were carried out 20 meters from the shaft, a change in spectrum density at a depth of about 55 m was detected, which coincides with the actual location of the required mine working. The results of the search for caverns in the rock mass, when taking measurements at an angle to the object sought, showed the absence of sufficiently explicit boundaries of the caverns.

Keywords: geo-radar, geophysical research in underground conditions, shaft, rock massif, caverns, spectral seismo-profiling.
