Emulsion-type explosives having improved storage stability are formed by combining an aqueous solution of an inorganic oxidizing salt and an oil in the liquid phase with agitation in the presence of a fatty acid, e.g., oleic or stearic acid, and an ammonium or alkali metal hydroxide, and incorporating dispersed gas bubbles or voids in the resulting water-in-oil emulsion. An emulsifying system including a fatty acid salt is formed in situ. The product contains the fatty acid salt, fatty acid, and hydroxide in a stabilizing equilibrium which permits the product to retain its explosive properties after storage at temperatures as high as 49°C. or more.

A method of producing an emulsion-type blasting composition comprising combining an aqueous solution of an inorganic oxidizing salt and a carbonaceous fuel in the liquid phase with agitation in the presence of a fatty acid and ammonium or alkali metal hydroxide, and incorporating dispersed gas bubbles or voids in the resulting water-in-oil emulsion. An emulsion-type explosive composition comprising: (a) a carbonaceous fuel forming a continuous emulsion phase; (b) an aqueous solution of an inorganic oxidizing salt forming a discontinuous emulsion phase dispersed within said continuous phase; (c) dispersed gas bubbles or voids comprising at least about 5 percent of the volume of said composition; (d) an ammonium or alkali metal salt of a fatty acid; (e) a fatty acid; and (f) an ammonium or alkali metal hydroxide in an amount in excess of that which will form by the hydrolysis of said fatty acid salt in water.
