Abstract
The present invention provides a method for producing a gassed explosive composition, comprising the steps of: (a) providing a base explosive composition comprising at least an emulsion explosive composition containing a source of ammonium ions; and, (b) combining the base explosive composition with a gassing solution subsequent to the formation of the emulsion explosive composition, the gassing solution comprising a pH lowering agent. A gassed emulsion explosive composition is also disclosed.

A method for producing a gassed explosive composition, comprising the steps of:
- a) providing a base explosive composition comprising at least an emulsion explosive composition containing a source of ammonium ions;
- and,
- b) combining the base explosive composition with a gassing solution subsequent to the formation of the emulsion explosive composition, the gassing solution comprising at least one Lewis Acid.
A method for producing an explosive composition comprising:
- a) providing a base explosive composition comprising at least a water-in-oil emulsion explosive composition, the water-in-oil emulsion explosive having a discontinuous aqueous phase containing ammonium ions;
- b) providing a gassing solution containing nitrite ions and at least one Lewis Acid;
- and,
- c) combining the base explosive composition with the gassing solution subsequent to the formation of the base explosive composition.
A gassing solution for a base explosive composition comprising at least a water-in-oil emulsion explosive composition which contains ammonium ions in a discrete aqueous phase, the gassing solution comprising at least one source of nitrite ions and at least one Lewis Acid, wherein the at least one Lewis Acid is present in an amount sufficient to lower the pH of the gassing solution to a level at which nitrite ions in the gassing solution are reactive with ammonium ions to form a sufficient amount of gas to form a sensitized explosive composition.
