О. Khomenko The phenomenon of zonal disintegration of rocks The analysis of the paradoxical phenomenon of zonal disintegration of rocks, which appears in all known forms of deformation of the array. An analytical model that correctly describes the phenomenon using a synergistic approach in the study, the use of thermodynamic, improved entropy and elaborately energy methods. The dependencies of the size and shape of energy bands, their number and conditions of the transition to a state of imbalance, form a ring-shaped area defined by the deformation of the array and the dynamics of formation of zones appearing in the protective capsule that forms around an array of underground workings.
