An explosive composition comprises a blend of a solid particulate oxygen-releasing salt and a melt-in-fuel emulsion wherein the melt-in-fuel emulsion comprises a discontinuous oxygen-releasing salt phase, a continuous water-immiscible organic fuel phase and an emulsifier component. The exposive composition contains less than 4% water by weight of the melt-in-fuel emulsion and typically comprises 60 to 95% by weight of particulate oxygen-releasing salt and 3 to 40% by weight of the emulsion. The explosive composition provides increased storage stability over corresponding compositions containing water-in-oil explosive emulsions. They have surprisingly good resistance to caking and segregation and are therefore especially suitable for blow loading into boreholes, particularly upwardly inclined boreholes. |
