Velocity of detonation measurement and …
1.1. Velocity of detonation measurement. Explosives with low VOD will have low impact on rock fragmentation than the ones with high VOD (Chiappetta, 1988, Heit, 2011). According to Cooper (1996), the explosive VOD is commonly used to approximate the detonation pressure and subsequently the explosive shock energy contained in an ideal explosive.
