Approximately 75 percent (or 2 billion pounds per year) of all explosives and blasting agents used in the United States is ammonium nitrate-fuel oil (AN-FO). Strip mining accounts for about 50 percent of the total AN-FO consumption, and construction, metal mining, and quarrying account for about 50 percent. The federal Bureau of Mines, to help resolve some of the confusion about proper AN-FO utilization, initiated an investigation to vary pertinent parameters that are under the control of the mine operator and to determine their effects on detonation velocity of AN-FO. This paper reports on those investigations.
