Abstract: The application of electro tomography for the purpose of assessing the possibility of hydrogeological connection between hydraulic waste disposal and underlying massif for the development of a set of measures to ensure the safe conditions of the mining operations is considered. The research was performed from the surface of water using a multi-electrode electroprospecting station and a set of electroprospecting cables. As auxiliary equipment, a small boat with an outboard motor and a GPS receiver were used. The approaching arrangement of segments of electro-reconnaissance scythes was used to change the extent of the geophysical profile. The scheme of geophysical profiles based on the analysis of mining-geological and mining documentation is substantiated and coordinated with the management of the coal-mining enterprise subdivisions. Specialized floats have been designed to protect the contact between the electrode and the electrical lines from water have been developed. Additional measurements of the depth of the hydraulic waste disposal by direct methods outside geophysical profiles have been carried out. The results of field studies of hydrogeological conditions of a section of a coal-bearing massif and estimation of geometric parameters of a hydraulic structure based on the use of electrical prospecting and the construction of an average geoelectric section are presented. Dependence of soil moisture content on electrical properties is determined in accordance with the normative documents in the field of electrical prospecting. A 3D model of the hydraulic structure has been constructed and the volume of accumulated water in the hydraulic waste disposal has been determined.
