Since the 1970 s, it has been recognised that rock fragmentation by blasting affects secondary fragmentation, loading, hauling, crushing and grinding (Zeggeren & Chung 1975). Theoretical analysis indicates that if the energy of the blasting is increased, the overall energy efficiency of size reduction from blasting to grinding can be improved.
