Anfos are based on a mix of prilled ammonium nitrate and fuel oil. The Anfos are explosives for mass blasting, which are used outside populated areas as column charges as well as in tunnel blasting.
Anfo (sack with white base) is not water resistant, so it cannot be used in water holes (density about 0,9-0,95 kg/dm3).
Ahti-Anfo (sack with blue base) endures moisture quite well. Ahti-Anfo can be charged in water holes, provided that the water is blown dry before charging (density about 0,9-0,95 kg/dm3).
