    Repumpable Emulsion/ANFO Blends: the Best of Both Worlds

    By Todd B. Harrington, Dennis M. Lydon, Walter B. Sudweeks

    Heavy ANFO products made by mixing ANFO (or AN prills) with a relatively small amount of emulsion (typically 15-30 percent) have become very popular in recent years. They are less expensive than strai
