Abstract

Inter alia, a low-density water-gel explosive composition characterised in that it comprises a continuous phase of aqueous inorganic oxidizer salt solution, a thickening agent, optionally a cross-linking agent, fuel and density-reducing agent in an amount sufficient to reduce the density of the composition to less than 0.8 g/cc is disclosed. The composition has good water-resistance and is especially useful in blasting applications calling for lower energy explosives.
