Influence of Three-Dimensional Stress Field Variation on Fracture Evolution Characteristics of a Roof

Influence of Three-Dimensional Stress Field Variation on Fracture Evolution Characteristics of a Roof

Excavation disturbance on the dynamic variation of the three-dimensional stress field is the main cause for the dynamic disasters of the surrounding rock mass of the roof. The stress condition in the surrounding rock mass of the roof during entry excavation and its impact on entry stability are syst...
