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. The explosive composition offers the advantage of utilizing relatively inexpensive fuel oil as a secondary fuel in a melt explosive composition without loss of detonation sensitivity of the composition on storage. The explosive compositions also show good retention of detonation sensitivity under conditions of applied static pressure, for example, in deep boreholes.
