To the evaluation of stability of anisotropic rock massif with the system of long cylindrical workings
A diagram method is presented of establishing of areas of stability and instability of two-connected rock masses with strength anisotropy, based on fixing of moments of initial «closing up» of zones of continuity destruction of two prolonged cylindrical workings. Quantitative analysis has been made of breakage and stability of two-connected masses depending on the characteristics of simulated surrounding and mutual location of workings.
