High VOD explosives are more suitable in hard rock and low VOD in softer rock. Generally, explosives with a lower VOD tend to release gas over a longer period and consequently have more 'heave'. The VOD range in commercial explosives is m/s. Density The density of a explosive determines the charge weight per meter of hole.
