Abstract
The authors discuss application of the modern concept on rock mass structure as a hierarchy of blocks and the phenomenological basis of the pendulum wave theory in the context of source areas of destructive events in natural and nature-and-production systems. The phenomenological relationship is set between Zhurkov’s concentration criterion of fracture, experimental criterion of underground excavation “collapse,” canonical structure of spectrum of pendulum waves by Oparin and the long-range action of heavy explosion impacts in geomedia by Sadovsky-Adushkin. The article validates the energy approach to describing transformation of elastic energy of destructive event source areas into kinetic energy of structural elements of these areas. The authors introduce a new notion of “interference seismic emission events.”
