EXPERIENCE IN APPLYING GEOPHYSICAL METHODS TO ASSESS THE TECHNICAL CONDITION OF THE TAILINGS DAM

Abstract

As a result of applying a complex of geophysical methods on the enclosing dams of the Dniprovske tailings dump, including the method of the natural pulsed electromagnetic field of the Earth and vertical electrical sounding, the areas of increased soil moisture that make up the body of the dump were identified, their spatial position and depth from the surface were determined. It is shown that the position of these areas has not changed over the past six years, which indicates that they are reliably fixed using a set of applied methods. Control drilling showed the presence of moistened soils in these areas. As recommendations to prevent the further development of hazardous engineering and geological processes in the dam body, a number of measures are proposed to monitor the technical condition and develop a project to restore the technical condition to regulatory indicators.
