CA 2675167

The invention provides a method for gassing an explosive to sensitise the explosive and/or modify the density of the explosive. The method comprises reacting at least one oxidiser with at least one nitrogen containing compound in the explosive to generate nitrogen gas. The explosive is formulated to effect diffusion of the oxidiser and/or the compound into contact with each other, the nitrogen gas being generated by oxidation of the compound by the oxidiser. The invention extends to the explosive compositions themselves.

La présente invention concerne un procédé de gazage d'un explosif, destiné à sensibiliser ce dernier et/ou à en modifier la masse volumique. Le procédé selon l'invention consiste à faire réagir au moins un oxydant avec au moins un composé contenant de l'azote dans l'explosif, afin de générer de l'azote gazeux. Ledit explosif est formulé de manière à permettre la diffusion de l'oxydant et/ou du composé en contact l'un avec l'autre, l'azote gazeux étant généré par l'oxydation du composé par l'oxydant. L'invention se rapporte également aux compositions explosives en tant que telles.
