Библиографическое описание: Determination of the Magnetic Field Coordinates of BMM Sensors Under a Collapsed Rock Mass Array for Assessing Ore Body Contour Displacement : научное издание / Andrey O. Shigin, Danil S. Kudinov, Ekaterina A. Kokhonkova, Vyacheslav V. Romanov. - Текст : непосредственный // Geosciences (Switzerland). - 2025. - Т. 15, № 8. - P. 292. - ISSN 2076-3263, DOI 10.3390/geosciences15080292.
Аннотация: <jats:p>This article analyzes the operating principle of the BMM sensor emitter in order to improve the accuracy of the wireless determination of the BMM sensor coordinates under a massif of destroyed rock in the context of the problem of determining the shift of rocks during gold ore mining. Using numerical simulations, FEM has been developed to develop digital models reflecting individual cases of the propagation of the magnetic field of the emitter located in various geological conditions and positions relative to the rock surface and the vertical axis. The accuracy of determining the coordinates of the radio beacon in the rock has been analyzed, and data on the deviation of the coordinates of the peaks of the magnetic field strength from the radio beacon axis have been obtained in cases of a heterogeneous composition of the rock massif, the influence of the deviation of the emitter axis angle from the vertical, the influence of the unevenness of the collapse relief, and the influence of the superposition of fields from different radiation sources. A study has been carried out to determine the direction of the radio beacon search based on the resulting vector of the emitter’s magnetic field strength.</jats:p>
