PCT No. PCT/GB95/02390 Sec. 371 Date Aug. 1, 1997 Sec. 102(e) Date Aug. 1, 1997 PCT Filed Oct. 10, 1995 PCT Pub. No. WO96/11172 PCT Pub. Date Apr. 18, 1996A watergel explosive composition is described which contains an oxidiser salt, a sensitiser, a thickener, a crosslinking agent, a fuel and less than 8%, by mass, of the composition of water. The explosive composition is cap sensitive in packages or cartridges having a diameter of about 26 mm or less at temperatures below about 5 DEG C. when detonated with a standard number 6 strength detonator. The explosive composition does not require a supplementary sensitisor or a perchlorate salt to achieve this cap sensitivity. A method of producing the explosive composition by separately preparing a thickened aqueous phase and a dry phase, and allowing the thickened phase to stand for a period of time before the mixing of the two phases, as well as explosive paper cartridge containing the watergel explosive composition, are also described. |
