The purpose of the work is to develop a model for the release of potential energy accumulated in the rock mass during the rapid mining of mineral deposits. Research methods - monitoring of technogenic seismicity by the ARAMIS M / E system for accumulation of data on the coordinates and energy of technogenic seismics in the field conditions of an underground coal mine; mine instrumental observations of the manifestations of mountain pressure with the help of deep and contour benchmarks to calibrate the model of release of potential energy; laboratory tests of the strength of rocks in unevenly component elastic state taking into account different speed of their loading; methods of physical modeling using equivalent materials to refine the model of release of potential energy of deformation of the mountain massif; computer simulation methods (PFC, FLAC3D) for calculating the coordinates and energies of man-made seismic events during offshore mining; methods of artificial neural networks and genetic algorithms for predicting the coordinates and energy of anthropogenic seismic. Known cases of man-made seismicity accompanying the underground development of solid minerals are analyzed. The mechanism of technogenic seismicity is investigated and the model of dynamic destruction of the rock massif, accompanied by technogenic seismicity, is improved. A distinctive feature of this model is the consideration of the speed of movement of the mining front, which improves the accuracy of predicting the coordinates of dangerous dynamic events and the accuracy of estimation of their energy. The system of prediction of dangerous technogenic dynamic phenomena for their prevention is theoretically substantiated and developed. Product Description popup.authors Ilyashov Mihail O.
