CALCULATION PROCEDURE OF STRESS-STRAIN STATE OF ROCK MASSIF ROUND OPEN AND UNDERGROUND WORKINGS

The applied problem of determining the mechanism and regularities of change of stress-strain state of the massif taking into account workings which application increases safety and efficiency of mining operations is solved in this work. As a result of research acrozones of influence of a pit and underground workings depending on depth of mountain developments and an arrangement of bins, minimum pillar arch at which it is formed the sink and coefficient of a stability factor are defined.
