A process and apparatus for preparing cap sensitive water-in-oil explosive emulsion compositions on a commercial basis is provided which includes mixing a hydrocarbon fuel component, an emulsifier, and an aqueous inorganic oxidizing salt solution under mixing conditions sufficient to obtain an emulsion matrix coposition and thereafter blending microbubbles with the emulsion matrix, the microbubbles being introduced to the emulsion matrix from a deaerated reservoir thereof.


A process for producing explosive emulsion compositions sensitized with microbubbles comprising: (a) forming an aqueous inorganic oxidizing salt solution of at least about 64% by weight inorganic oxidizing salts and maintaining said solution above the crystallization temperature thereof; (b) forming a hydrocarbon fuel component and heating it to approximately the same temperature as said oxidizing solution; (c) introducing said oxidizer solution, said hydrocarbon fuel component, and an emulsifier to a mixing zone and mixing at conditions sufficient to ob...
