ABSTRACT
Analytical studies of stress-strain state of rock massif around the chamber of second stage development using thermodynamic method are fulfilled. The effect of mining depth development on the stress state is established. The empirical equations of dependences the radial stresses on depth development and distance to the chamber of second stage was received.
