Abstract

Introduction. Geophysical exploration at a brine storage pond dam of Mirny Mining and Processing Division (MPD) were carried out in order to provide safe operation. A new approach to electrical logging data interpretation is based on past records generalization.
Research aim is to create a forecast electrodynamic model of a storage pond dam.
Research methods included thermometry (measurements in the network of thermometric wells), piezometry (water level measurements in observation wells), land surveying (dam surface releveling), electrical resistivity tomography (aerial electrical exploration at a dam), and visual observations at a dam.
Results and analysis. The regularities in electrical resistivity (ER) variation were determined at diff erent depths in the three parts of a dam which were distinguished by the technogenic impact. Quantitative assessment of ER variations in diff erent part of a dam was given depending on the thawing process time and the temperature of the environment. Calculation results and their interpretation were analyzed with the account of geological structure features of a hydraulic engineering structure.
Summary. The principles of forming a forecast electrodynamic model were created. A model for one storage pond dam was built as an example. The development of a generalized model for hydraulic  engineering structures is possible if data from several sources is stored.

Key words: storage pond dam; electrical resistivity tomography; thermometry; forecast; electrodynamic model.
