A blasting composition of reduced volume strength relative to straight ammonium nitrate/fuel oil (ANFO) compositions, containing particulate oxidizer salt, particulate inert and/or density reducing filler and optionally a fuel for modifying the oxygen balance. The composition contains a viscous water-in-oil type emulsion, having a continuous fuel phase and a discontinuous aqueous phase of oxidizing salts, in an amount sufficient for improving adherence between the particulate oxidizer salt and the particulate filler, but insufficient for filling out the ...


A method for the production or delivery of a reduced volume strength blasting composition, comprising the steps of: a) preparing a particulate blasting composition, having a volume strength relative to standard ANFO reduced to below 80%, said standard ANFO consisting of prilled ammonium nitrate with 5.5 percent by weight of fuel oil and tamped to a charge density of 0.95 g/cc, by mixing: (i) a particulate oxidizing salt; (ii) an energy reducing inert or density reducing filler or mixture thereof effective to produce reduced volume strength; and (iii) a v...
