Abstract

The data on stress-strain state around an underground excavation in an unstable rock mass are reported. For overburden pressure relief, it is proved necessary to create a damping layer, and the related drilling-and-blasting parameters are determined. Zones of probable fracture of rock mass under camouflet blasting are identified.
