  • Chemical foaming of emulsion explosive compositions
    Patent number: 4875951
    Abstract: This invention provides an improved method of foaming a water-in-oil emulsion explosive wherein a gassing agent which is a water-in-oil emulsion containing an aqueous solution of sodium nitrite in its discontinuous phase is mixed with the emulsion explosive. The sodium nitrite reacts with ammonium nitrate in the discontinuous phase of the emulsion explosive to generate small particles of gas which are distributed throughout the explosive. The method improves the gas bubble distribution and enhances the sensitivity of the explosive to blasting cap initiation.

    Date of Patent: October 24, 1989
    Assignee: Imperial Chemical Industries PLC
    Inventors: David W. Prest, William J. Yorke
  • Water-in-oil emulsion blasting agents containing unrefined or partly refined petroleum product as fuel component
    Patent number: 4404050
    Abstract: A water-in-oil emulsion explosive composition is provided wherein the continuous carbonaceous oil or fuel phase comprises an unrefined or partly refined petroleum product, for example, slackwax. The resulting explosive composition exhibits properties of strength, detonation velocity and stability comparable and in some cases superior to similar compositions containing refined petroleum fuels.
