The results of detailed EM soundings in the problem zone at the northern border of Dombrovsky quarry
The results of electro-magnetic diagnostics of the medium in the upper part of geological cut between river of Sivka and the northern border of quarry are presented. Time domain electromagnetic sounding has detected and quantitatively outlined a zone of anomalous conductivity associated with development of filtration-suffosion and karst processes in the gypsum-clay cap and in the ore body as a result of infiltration of river waters and atmospheric precipitations into water-bearing horizon, and their migration in the border zone at lower hypsometric dates.
