  • Patent number: 8187397
    Abstract: An explosive emulsion to be used in conjunction with a gas-producing agent, such as sodium nitrite, to form an explosive emulsion with a density between 0.50 g/cm3 and 0.90 g/cm3. The present invention also includes the method for producing the explosive emulsion. The explosive emulsion is stable for at least 96 hours with nitrogen bubbles, having a predetermined dimension range, homogenously distributed. To maintain this low-density explosive emulsion stable, between 84% and 95% by weight of an oxidizing solution is combined with 5% to 16% by weight of a fuel solution. The fuel solution includes solid cacao fat as a stabilizing agent and stearic acid to prevent the combination of the nitrogen bubbles. The method for producing the oxidizing solution includes combining ammonium nitrate, sodium nitrate, thiourea, urea, and water at a temperature between 80 and 90 degrees centigrade. In another step of the method, a fuel solution is produced by combining an emulsifier, oil, diesel No.
