The fragmentation of rock is fundamental to mining. It is the first preparatory stage in the extraction process – making rock small enough and loose enough to be efficiently excavated.

But this simple statement underestimates how important this activity is for the whole mining operation. By optimising rock fragmentation by blasting, you can achieve significant improvements in waste productivity, mill throughput, fragmentation profile and wall stability.

Stuart Thomson, Orica's Global Bulk and Packaged Explosives Product Manager, explains in this paper how blasting improves productivity and environmental performance with some innovative new Orica products.
