About One Mechanism of Formation of Zone Decomposition of the File of Rocks Round Excavations

摘要：

The problem about soft stressing of a file of rocks with development of the rectangular section is solving. It is supposed that the file material has an outrageous site of deformation with some value of the module of recession. It is required to estimate the deformation of a file of rocks around the excavation when the loadings enclosed to infinite points grow (on absolute size) proportionally time and the material near the excavation is in outrageous state. Calculations show increasing of displacement speeds in the field of destruction and rising of kinetic energy of particles. Proceeding from it, the criterion of the zonal disintegration formation of a file of rocks which have been found out in(1-4) and connected with achievement of density of kinetic energy of a given value is formulated.
