Scientists at the Institute of Petroleum Geology and Geophysics are developing methods to build models to estimate tailings volume based on electrical tomography, electromagnetic profiles and aerial photography data. AA Trofimuk (INGG) SB RAS.
The new technique, taking into account the results of geochemical analysis, allows us to obtain highly accurate data. Scientists have already successfully used it to study waste dumps of different types, such as the Beloklyuchevskaya landfill, the Komsomolsk hydraulic landfill, and the Talmovsky sands.
Researchers have identified areas suspected of leaks of highly mineralized solutions from landfills into groundwater. They also built geoelectric models of tailings dumps, which allowed estimating the volume of waste that potentially contains valuable (gold, silver) and toxic (arsenic) elements.
Modern equipment was used in the construction of the models: EMS-AEMP14 developed at INGG SB RAS for electromagnetic profiling, the SKALA complex, Russia, for electrical tomography and unmanned aerial vehicles for aerial photography.
The INGG SB RAS spoke about the research carried out: “Data on the volumes of technogenic sediments obtained by geophysical methods with verification by geochemical sampling data can additionally be used to calculate the masses of specific substances (for example, precious and non-ferrous metals or dangerous lead, arsenic, etc.) contained in tailings dumps”.
