Stress-strain state of rock massif and backfill around chambers of second stage mining

What is it about?

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 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 treatment chamber surrounding the second stage of mining floor 840 - 940 m are established.
