Safety of underground mining is significantly complicated if horizontal tectonic stresses hugely predominate over vertical ones and influence of tectonic disturbances, heterogeneities of physical-mechanical properties of rocks and mountainous relief is considerable. To the date multiply efficient tool methods have been developed aimed at estimation and forecast of rockburst hazardous events in the highly-stress rock mass. They allow studying the stress-strain state of the rock mass in the vicinity of underground m...
