Blast-Induced Damage on Millisecond Blasting Model Test with Multicircle Vertical Blastholes
To investigate the blast-induced damage effect on surrounding rock in vertical shaft excavation, 4 kinds of millisecond blasting model tests with three-circle blastholes were designed and carried out with excavation blasting in vertical shaft as the background. The longitudinal wave velocity on the...
