Anfo Versus 100% Emulsion: Quantitative Assessment of Performance With Constant Drilling and Blasting Costs
By Neal Lee, Braden Lusk, John Silva Castro
One of the most common assumptions regarding the use of ANFO versus utilizing 100% sensitized emulsion is that ANFO “turns over” the muck-pile better, due to the “higher gas volume” supposedly inheren
