Abstract: The urgency of the discussed issue. With increasing depth the development of the Tashtagol Deposit has increased the risk of rock bursts. With 300 m appeared shooting rocks, and with a depth of 600 m began to emerge rockbursts, micro impacts and shocks; up to 760 m number dynamic phenomena has increased. Acting at present the method of prediction of rock bursts has low reliability. The main aim of the study: Development of recommendations for improving methods of prediction of rock bursts in iron ore deposits. The methods used in the study: Methods of mathematical modeling is to quantify the degree of influence of the contact of the rock layers in raspredelenie CUES in the array. Methods of approximation theory is to assess the adequacy of the theoretical curves to the experimental data by comparison. The results: The influence of the vertical flat contact of two media with specific elektrosoprotivleniya on the options field of a point source, as well as the model of an inhomogeneous medium, representing the half-space of several steep seams with flat borders. Developed recommendations for improving the prediction of rock bursts in mines using elektroproprivod.

Key words: electric profiling resistivity rock burst homogeneous array the mine
