2017-6-20 If explosives cost would increase but produce better breakage and cost reductions could made in the other production costs then total production cost may radically decrease. If savings on drilling and blasting costs are desired it is important to determine the actual costs of the production process. What are the drilling and blasting costs per ton?

2012-1-1 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.
