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
Blasting is the first and lowest cost-per-tonne stage in the comminution value chain. The basic principle that effective blast design can optimise fragmentation from the run of mine (ROM) ore muck pile to improve productivity through digging, loading and crushing to grinding and increase mine site profits is well documented.

Apr 01, 2019 Rock fragmentation is a complex dynamic process relating to the interaction between rock mass and explosives. For this reason, a mature model has not yet been developed to meet all mining conditions and geological features (Siddiqui et al., 2009).In order to overcome this drawback, the main goal of this paper is to provide a new framework to evaluate and predict rock fragmentation
