PCT No. PCT/AU92/00050 Sec. 371 Date Jan. 21, 1994 Sec. 102(e) Date Jan. 21, 1994 PCT Filed Feb. 11, 1992 PCT Pub. No. WO92/13815 PCT Pub. Date Aug. 20, 1993.An explosive composition comprising an oxidising agent such as ammonium nitrate (AN), and a fuel material which may include a fuel oil (FO) and which also comprises a solid fuel such as rubber particles or polystyrene beads or flakes. The solid fuel is incorporated into the composition to provide for the controlled release of energy upon detonation of the explosive composition. It has been found that by substituting some or all of the liquid fuel oil with a slower burning solid fuel, the time during which the pressure builds up during detonation is lengthened. Thus a low shock energy explosive (LSEE) can be produced having reduced shock energy and increased heave energy compared to convention explosives, such as ANFO.
