For stone producers, blasting is the primary crushing stage. Thus, the efficiency of downstream processing hinges on the success of the blasting program. The growing popularity of high-accuracy electronic detonators means the potential for an expansion of a quarry blasting program's capabilities and improved safety as well. Precision timing, achieved with electronic detonators, can deliver consistent blast-to-blast results previously unobtainable with traditional pyrotechnic blasting systems, according to industry blasting experts.
