EXPLOSIVE

An emulsion explosive of the water-in-fuel type containing in its continuous phase a water immiscible fuel and at least a proportion of polymer in a liquid or in finely divided particle form. The explosive is particularly advantageous for use at low temperatures. The explosive may be made by emulsifying an aqueous solution or melt containing an oxidising salt and an aqueous dispersion of a polymer to form an emulsion in which the oxidising salt forms part of the discontinuous phase, and the polymer forms at least part of the continuous phase, the continuous phase forming a water immiscible fuel component.
