    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
