Abstract
The author assesses stress-strain state of rock mass during mining with room-work and ore drawing under protection of overhang. It is determined how stability of chamber pillars and roof rocks depend on the type of geomechanical conditions of ore extraction. Besides, the article gives safe parametric ranges of the described geotechnology and its application areas for each of the discussed geomechanical models.
