This invention relates to a method for rapid chemical gassing of an emulsion explosive without having toxic nitrogen oxides in the finished emulsion explosive product, when nitrite is used as the gassing component. Urea acts as a gassing accelerator and urea are added in the water lubrication solution or in both the water lubrication solution and in the gassing component. To achieve rapid gassing of an emulsion explosive, the emulsion is prepared at a pH in the range of 0-3, by using an organic acid having at least 3 carbon atoms.

L'invention concerne un procédé pour le passage rapide à l'état gazeux par voie chimique d'un explosif à émulsion, sans présence d'oxydes d'azote toxiques dans l'explosif réalisé, sachant que l'agent utilisé pour le passage à l'état gazeux est du nitrite. On ajoute de l'urée, qui accélère le passage à l'état gazeux, dans la solution de lubrification à l'eau ou bien dans cette solution et dans l'agent de passage à l'état gazeux. Pour réaliser rapidement le passage à l'état gazeux d'un explosif à émulsion, on élabore une émulsion selon un pH compris entre 0 et 3, en utilisant à cet effet un acide organique qui comporte au moins trois atomes de carbone.
