EXPERIENCE OF APPLYING THE COMPLEX OF GEOPHYSICAL METHODS TO DETECT KARST CAVITIES IN THE DUMPS OF POTASH MINES
The article describes the experience of applying the complex of geophysical methods to identify karst processes in the dumps of potash industry. For these purposes a rational complex has been experimentally determined comprising a vertical electric sounding method using a three electrode array and a reflection method by the procedure of common depth point with registration of p-waves. The selected complex has been tested by performance of geophysical works to solve exploration tasks and delineation of karst cavities in the body of salt tailings piles of the mines PJSC «Uralkali».
