The paper considers the contemporary level of hydrogeological investigations during prospecting of deposits. It is suggested to use numerical modeling, sensors, computer programs for pumping tests. These methods are illustrated by prospecting of the South-East Gremiakha deposit.
To form an estimate of stress state of rock mass of a sliding-down slope, in the town of Sochi 10 observation stations – bore holes were built-up at the depth of 50-150 m with the arranged sensing elements for hydrostatic pressure measurements. According to the results of observations which were carried out for two years, the regularities of groundwater flow were established, and also the hydrogeological structure of the sliding-down slope was revised. The sensor readings indicated the slight changes in stress state of the low-permeable paleogenic rock and overlaying sedimentaries. The periodical movements of overlaying sedimentaries of clay composition are attributed to the seasonal variations of their physical and mechanical properties.
