Abstract


The article provides with the results of a comprehensive assessment of the stability of the area near the karst sinkholes at Berezniki, Gaginsky district. The materials of geophysical surveys obtained by the method of vertical electric sounding were interpreted taking into account the karstological drilling data. Weakened zones are outlined along the apparent resistivity sections. Dependence of sounding results on the distance from the nearest sinkhole was analyzed. The intensity of sinkhole formation and the average diameter of the karst sinkhole were calculated.

Keywords
