Investigation of stress-strain state of rock massif around the secondary chambers

What is it about?

The analysis of stress-strain state of rock massif 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 the chambers of the second stage mining are given. The regions of destructive deformations and their dimensions in the array filling massif chamber surrounding the second stage of mining level 940 - 1040 m are established.
