A possibilities of dangerous dynamic phenomena prediction in a rock mass surrounding the excavations

Evolution of the stress-strain state in the rock mass with excavation is studied numerically. The non-equilibrium state of the rock mass and the conditions of its critical states, which result in catastrophic collapses, are investigated. It is shown that the features of a flicker (1/f) noise indicat...

Zusammenfassung:Evolution of the stress-strain state in the rock mass with excavation is studied numerically. The non-equilibrium state of the rock mass and the conditions of its critical states, which result in catastrophic collapses, are investigated. It is shown that the features of a flicker (1/f) noise indicating multiple fracture in the roof and floor suggest proximity of the critical state.
