Abstract. A comparison was made between results of theoretical investigations of chaotization causes in nonlinear dissipative dynamical systems and results of processing rock massif responses to explosion actions using the method of phase diagrams. Detailed seismic mine catalog data of the Tashtagolsk mine for two years, from June 2006 to June 2008, served as experimental material.
The theory implies that the general cause of chaotization and stochastization of dynamical system movements is the losses of their stability and exponential recession of close phase trajectories. That result coincides with phase diagram analysis, developed using data of a seismic mine catalog.
Detailed analysis was performed on temporal changes in the types of correlation relations of the functions of energy, absorbed and released by the massif. Conditions of Bogolubov’s algorithm application to analysis of accumulation and energy release under explosion impact on the massif were analyzed.
Keywords: nonlinear model of massif response, seismic mine catalogue, analysis of natural data by action of massif response.
