Abstract
Emulsion explosive sensitive to a detonator, which can be initiated with a conventional detonator no. 8, of water-in-oil-emulsion type containing sensitizers which, as opposed to types known previously, here comprise aromatic nitro-compounds, in which emulsion the organic phase consists primarily of the aromatic nitro-compounds and the water phase consists primarily of a water solution of inorganic oxidizing salts and in which emulsion emulsifier is also included; detonation stabilizers in the form of particles with enclosed or adsorbed gas ("hot spots"); additional fuels such as aluminium, urea, etc.; optional stabilizers for the organic phase and for the water phase; and possibly an agent to lower the crystallization point.
Claims9
An emulsion explosive of the water-in-oil type which is sensitive to a no. 8 detonator, consisting essentially of:
- 5-20 percent by weight of an organic phase consisting of aromatic nitro-compounds as a sensitizer, said nitro compounds being selected from the group consisting of mono-, di- and tri-nitro toluenes, mono-nitro benzene, di-nitro benzenes, mono- and di-nitroxylenes and mixtures of said nitro-compounds;
- 5-18 percent by weight water;
- 0.5-4 percent by weight of an emulsifier with a hydrophile-lipophile balance less than 7;
- 1-10 percent by weight of inorganic particles with enclosed or absorbed gas as "hot spots";
- and
- 60-90 percent by weight of inorganic oxidizing salts in the water phase.
