Abstract

A sensitized explosive composition, and a method of production therefor, wherein the composition is sensitized by the addition of a gas void-containing, gas-in-liquid foam to a base explosive composition. The foam is produced in water or in a non-aqueous liquid carrier and is, preferably, stabilized by the addition of viscosity control and foaming agents. The explosive composition may be, for example, a water-in-oil emulsion explosive or an oil-in-water slurry explosive. The sensitized explosives thus produced are manufactured by a method having improved safety, greater low temperature manufacturing flexibility, and are more economical than microballoon gas void-containing explosives of the prior art.
