Porous Prilled Ammonium Nitrate is used in the Manufacturing of ANFO.  ANFO has found wide use in coal mining, quarrying, metal mining, and civil construction in undemanding applications where the advantages of ANFO’s low cost and ease of use matter more than the benefits offered by conventional industrial explosives, such as water resistance, oxygen balance, high detonation velocity, and performance in small diameters. ANFO is also widely used in avalanche hazard mitigation.
