Abstract: This invention concerns a melt explosive composition which comprises as a first component a melt which is pourable, pumpable or flowable at a temperature in the range of from -10.degree. C. to +90.degree. C. and which comprises at least one oxygen-releasing salt, for example ammonium nitrate, and at least one melt-soluble fuel material, for example urea, and as a second component oiled prills of ammonium nitrate.
