Abstract EN
Many sudden disasters (such as rock burst) by mining extraction originate in crack initiation and propagation.
Meanwhile a large number of shock waves are produced by rock deformation and failure.
With the purpose of investigating crack coalescence and failure mechanism in rock, experimental research of rock-like materials with two preexisting flaws was performed.
Moreover, the AE technique and photographic monitoring were adopted to clarify further the procedure of the crack coalescence and failure.
It reveals that AE location technique can record the moments of crack occurrences and follow the crack growth until final failure.
Finally, the influence of different flaw geometries on crack initiation strength is analyzed in detail.
This research provides increased understanding of the fracture mechanism of mining-induced disasters.
