Fuel phase for use as a continuous phase together with a discontinuous aqueous oxidizing salt phase in water-in-oil emulsion explosives, comprising a carbonaceous fuel and at least one but not all components of a gassing system; process for the preparation of a water-in-oil emulsion explosive by emulsifying an aqueous oxidizing salt phase into a carbonaceous fuel phase and introducing into the emulsion voids by using a gassing system, characterized in that at least one but not all components of said gassing system is distributed in at least part of the fuel phase and that the salt phase is then emulsified into the fuel phase containing salt component; and a water-in-oil emulsion explosive system in two-pack form, wherein one pack comprises an aqueous oxidizing salt phase containing at least one but not all components of a gassing system and the other pack comprises a carbonaceous fuel phase containing the remaining components of said gassing system.
