Influence of diameter of empty hole on the fragmentation effect of parallel cut blasting under confining pressure
Cut blasting is the key technology for roadway blasting excavation. High confining pressure has obvious inhibition effect on cut blasting effect, while empty hole is of great significance to improve cut blasting efficiency, but the relevant research is not sufficient so far. To study the crushing ef...
