ABSTRACT:
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 interstices between the particulate oxidizer salt and the particulate filler.
