Seismic events in mines are related to both natural and induced processes 1-5. Unique factual data obtained in the course of comprehensive monitoring in two mining districts of the Ural region make it possible to formulate the issue, reveal and compare specific features of the dynamics of seismic processes, and elucidate cause-and-effect relations between the external (induced and natural) influences, on the one hand, and seismic events, on the other hand. We can assume that natural rock bodies are mul-tioscillatory systems functioning in seasonal and other regimes. Rocks are likely to be capable of synchronization with external influences and desynchronization. The medium probably does not respond to some weak actions at certain time intervals.
