In the present time an approach is widely developed when the rock mass is considered as an energy-active hierarchical-block medium. The blocks of this medium are constantly interacting with each other and exchanging energy under the influence of various factors. In the intact rock mass the energy dynamic equilibrium of the medium is maintained due to constant energy feeding and, at the same time, due to continuous processes of structural discontinuities destruction on different levels.
