Demilitarized Double Base Propellants as Ingredients of Commercial Explosives

Lipińska K., Lipiński M., Maranda A.

Central European Journal of Energetic Materials

2005

Vol. 2, nr 1

69-78

Demilitarized energetic materials such as explosives and propellants are a useful source of energy for civilian applications. The excess of military explosives and propellants can be reused as components in commercial explosives. The influence of double base propellants (DBP) on detonation characteristics of ANFO and emulsion explosives was investigated. Some physical characteristics of emulsion matrix and ammonium nitrate prills (densities, size distributions and structure examinations by scanning electron microscopy) were determined. Investigated explosive mixtures contained 20, 40 and 60% of the propellant. The velocity of detonation and intensity of blast waves (peak blast overpressures) generated by the explosion of the mixtures was measured. Positive phase impulses were also calculated. In the case of ANFO/DBP compositions their parameters increased along with the propellant content.
