Abstract

Summary

Modern mining processes in Ukraine are accompanied by environmentally hazardous geomechanical events, including activization of exogenous geological processes and local increased induced seismicity. Using the example of Kryvyi Rih iron ore basin (Kryvbas) the interrelation between increase in technogenic overload and modern geodynamic activization is shown. Complex macro-seismic with micro-seismic research in deep mines solves the problem of determining of basic parameters of induced seismicity and activization of dangerous exogenous geological processes of not-seismic old-industrial Kryvbas. These data are necessary to prevent accidents at mining hydraulic facilities (and first of all - tailing ponds) and successfully design their increase. On an example of detailed geophysical research near the storage pond of highly mineralized mine waters in Svistunovo gorge (Southern Kryvbas) is shown that emergency sites of hydraulic objects can be not only dams, but also the bottom. Here intensive tectonic fragmentation of rocks (on joint interpretation of gravimetric, magnetic and electrometric observations) is the reason for increasing filtration parameters and deterioration of physical and mechanical properties of rocks and, as a result, dangerous intensification of exogenous geological processes, an emergency emptying of the pond and contamination of underground water.
