EXPLOSIVES WHICH IS MIXTURE OF ANFO AND WATER IN OIL EXPLOSIVES

摘要

PURPOSE: An explosive by mixing an ammonium nitrate-fuel oil explosive and an emulsion explosive is provided to improve the density of the explosive by mixing the W/O type emulsion explosive with the AN-FO explosive and to improve the water-proofing in a base rock. CONSTITUTION: The explosive by mixing the ammonium nitrate-fuel oil explosive and the emulsion explosive includes the W/O(water in oil) type emulsion explosive and the ammonium nitrate-fuel oil explosive. The explosive is composed of an oxidizer water solution, in which ammonium of 60-90 and water of 5-30 are contained, the mineral oil of 3-15, an emulsifier of 0.5-10.0 and minute hollow body of 0.5-2.00. The sodium nitrate of 0.1-10 is added to the oxidizer water solution. PIBSA(Polyisobutenyl Succinic Anhydride reacted with an alcohol Anhydride) and SMO(Sorbitan Monooleate) are contained in the emulsifier.
