Shock wave interactions in rock blasting: the use of short delays to improve fragmentation in model-scale

D Johansson, F Ouchterlony - Rock mechanics and rock engineering, 2013 - Springer
A series of detailed small-scale tests have been made to investigate the use of short delays
to promote better fragmentation caused by shock wave interactions. The block design had a …
