Abstract

Abstract A self compacting explosive cartridge for use in bore-holes. The cartridge is formed from rigid, upper and lower telescoping tubes which extend centrally through a larger diameter sleeve of flexible material. Prilled ammonium nitrate fills the annular space between the tubes and the sleeve; the upper tube is filled with diesel fuel and the lower tube contains a detonator. When remotely activated by a signal, compressive means included in the cartridge telescope the tubes together which foreshortens the cartridge and displaces the fuel from the upper tube into the ammonium nitrate causing the two chemicals to combine to form an explosive mixture. The foreshortening or setting of the apparatus compacts the explosive material in the bore-hole. The preferred form of the invention obtains the force for setting the cartridge from a stretched outer sleeve of resilient material. A modified form of the invention supplies the setting force with a tension coil spring concentrically disposed about the telescoping tubes. Another modification supplies the setting force with stretched rubber bands which connect the two ends of the cartridge to each other.
