ABSTRACT:
This invention concerns a melt explosive composition which comprises at least one oxygen-releasing salt, for example ammonium nitrate, at least one melt soluble fuel material, for example urea, and at least one naphthalenesulfonate derivative selected from the condensates of formaldehyde and naphthalenesulfonic acids and the alkali and alkaline earth metal salts thereof, for example disodium methylene-bis(naphthalene-.beta.-sulfonic acid). The explosive compositions show a considerable improvement in detonation sensitivity in small diameter boreholes.
