Application of electrical prospecting methods for technogenic bodies (stored wastes of the mining industry) studies: review

Abstract

The world experience of using electrical exploration methods in the study of technogenic bodies is considered, in particular: determining the zoning of tailings, groundwater migration routes and the stability of dams. The ongoing research demonstrates the high efficiency of combining the methods of geophysics, geochemistry, and hydrology. On the example of mining dumps located on the territory of the Kemerovo region and the Republic of Tyva, the achievements of the interdisciplinary team of the IPGG SB RAS are shown. The use of electrical resistivity tomography and magnetic prospecting in combination with geochemical mapping and gas survey made it possible to reveal the internal structure of tailings and dumps, outline watered horizons, and determine the transport of highly mineralized solutions to groundwater. Obtained results became the basis for creating a methodology for a comprehensive study of tailings and dumps, assessing the danger of technogenic bodies, and developing methods for minimizing their impact on the environment and the population of settlements.
