Abstract.  Generalization of the physical phenomena and conformities to law of evolution of the loaded geological environment is conducted. In appearance and growth of mikrocracks, frag-ments and particles a leading role is taken heterogeneity of the destroyed object. Influence of size of the destroyed object is analysed on the deformation, energy-critical density and acoustic emission. The differences of geological breed destruction mechanism are considered in mikro- and macro-systems. The informing parameters of material critical stage are carried out after tensile strength and destruction with the use of method of acoustic emission. The foundations, criteries and modes of functioning of rock are exposed. Energy of rock destruction is described by means of dynamic size effect. Practical possibilities of destruction effects estimation (formation of cracks, disintegrations, dispergating) on the basis of deformation and acoustic activity kinetics of loaded geological envi-ronment are carried out. For example, with the increase of acoustic calm duration after tensile strength it is possible to forecast the prepotent effects of destruction (dispergating).

Keywords: geological environment, destruction, energy-critical density, acoustic emission, au-toresonance.
