Abstract
The article presents the method of location of heavily fractured zones in rock mass. The method uses a geophysical model of electromagnetic radiation which accompanies discontinuity of rock mass. It is shown that for the location of a rock mass area with the change in the stress-strain behavior in the neighborhood of mine openings using the electromagnetic radiation method, it is required to assess the power of a source of rock failure by means of recording signals from sensors of electromagnetic radiation. An approach to building a software architecture to predict dynamic events induced by rock pressure is proposed.
