摘要：
The analyzes of stress-strain state of rock mass around the chambers of the second stage mining with using thermodynamic method are performed. The empirical equation dependencies of radial stresses on the distance from chambers of second stage mining are received. The regions of destructive deformations and their dimension in filling massif chamber surrounding the second stage of mining floor 840 - 940 m are established.
