The present invention provides a water-in-oil macroemulsion for use in combination with a solid oxidizer in preparing a high density explosive composition. The macroemulsion comprises 1-70% by weight of water, 5-85% by weight of a fuel oil, and 0.1-10% by weight of an emulsifier with an HLB number within the range 0-8. The invention also provides an explosive composition comprising 2-20% by weight of a water-in-oil macroemulsion as just described and 80-98% by weight of a solid oxidizer. The preferred solid oxidizer is selected from the group of ammonium nitrate, sodium nitrate, potassium nitrate, calcium nitrate, ANFO, and mixtures thereof. In addition, water soluble fuels, oil soluble fuels, or solid fuels may be added to the explosive composition. The invention further provides a method of preparing a solid oxidizer based explosive having a higher density than that obtainable in a mixture of fuel oil and the solid oxidizers. |
