GEOELECTRIC MONITORING OF THE GROUND DAM CONDITION OF MINE WATER RETENTION POND

 

Annotation. Monitoring of the state of ground hydraulic structures on the accumulators of liquid industrial wastes is an important engineering-geological and geoecological task. In this work the results of geoelectrical monitoring of Elchevsk ground dam of the mine water retention pond are presented. The methods of electrical sounding and induced polarization in the frequency domain were applied during the investigations. According to the distribution of specific electric resistance in the body and base of the dam in different years, the places, subject to the greatest changes depending on hydrological conditions, where increased water filtration from the reservoir is possible, have been found. Intensive anomaly of induced polarization was detected. The nature of the anomaly may be associated with the accumulation in the base of the structure and in the fractured rock of harmful chemicals contained in the sedimentation sludge.

Keywords: ground dam, mine water, filtration, pollution, electric resistance, frequency effect, induced polarization.
