Under-blasting can lead to signifi cant amounts of oversize rock which cannot pass through the crusher and will require size reduction before being taken to the crusher. Conducting fragment break-up is costly and needs secondary blasting or use of a mechanical hammer for rock disintegration. UNIQUE FACTORS THAT INFLUENCE FRAGMENTATION
Chemical Economics Handbook. The principal distinction between explosives and blasting agents is their sensitivity to initiation. Explosives are cap-sensitive, whereas blasting agents are not and therefore require a primer. Water gels and slurries may be either explosives or blasting agents. The many industrial and military uses for explosives ...
