  • Patent number: 5470407
    Abstract: Provided herewith is a method for preparing an explosive composition with an adjusted rate of detonation which matches the rock stratum in which blasting is to occur. The composition is comprised of a mixture of glass microballoons and plastic spheres, which mixture has been found to provide one with adjustable rates of detonation with essentially no significant difference in the carbon, hydrogen, oxygen, nitrogen and water contents or ratios and at the same time with the same overall energy.

  • Patent number: 5346564
    Abstract: The invention relates to a method of safely preparing stable water-in-oil emulsion explosives. After formation of the emulsion explosive, it is cooled in a heat exchanger which uniformly cools the emulsion. The physical characteristics of the heat exchanger also limit the extent of detonation if it should occur. In order to improve stability of the emulsion explosive, the oxidizer is blended with the emulsion subsequent to cooling the emulsion.
