electrical prospecting

Purpose. The purpose of this work is definition of potentially ecologically-hazard and karst-chasm zones and prediction of karst development near the Skhidnytsia-Pisochne highway on the area of mine No.2 of Stebnyk potassium deposit by electroprospecting method, namely time domain electromagnetic method (TDEM). Methodology. The research was carried out using the TDEM method in the modification of “the contour in the contour”. To study the upper part of the cross-section down to 100 meters, the digital equipment for electroprospecting “Stage” was used.

The experimental field geoelectric observations on the Peremyshlyanska oil and gas perspective area are done. The anomalous daily dynamics of electromagnetic fields using the TEM method is detecting. As a result of observations the anomalous zone is distinguished. It correlates with the oil and gas perspective zones which are distinguished by other methods (seismics, geochemistry, gravimetry).
