Design and Application of Blasting Parameters for Presplitting Hard Roof with the Aid of Empty-Hole Effect

Design and Application of Blasting Parameters for Presplitting Hard Roof with the Aid of Empty-Hole Effect

Theoretical calculation and numerical simulation were performed to analyze the mechanism of rock fracturing between holes in deep-hole presplit blasting, crack evolution under the synergistic action of dynamic and static loads, and the mechanism of fracture movement guided by tangential stress conce...
