The mining process begins with drilling and blasting activities. The efficiency of blasting affects all downstream operations such as loading, hauling, crushing and milling. Therefore drilling and blasting activities should be designed to ensure that designed parameters produce the desired fragmentation. The KuzRam model is a fragmentation prediction model and is widely used for predicting

Therefore, considering the fact that open cut blasting is mostly successful in mines, it should be feasible to use a much higher specific charge such as 3.0 kg/m 3 in mining production blasting. If so, when the cost in drilling and blasting is increased by a certain amount, the energy and cost in crushing and grinding might be largely reduced.
