Abstract
The present invention relates to packaged explosives and methods of manufacture thereof and more particularly to packaged emulsion explosives. The term "emulsion" as hereafter used shall mean an oil-continuous emulsion having a continuous organic fuel phase and a discontinuous oxidizer solution phase dispersed as fine droplets throughout the fuel phase. The term "explosive" shall mean a detonable composition which can be either cap-sensitive or noncap-sensitive, as desired. The term "packaged" shall refer to cylindrical tubes or sticks of emulsion explosive of any desired length and having a diameter of generally four (4) inches or less, although larger diameter products also can be made by the methods described herein.
Claims18
A method of manufacturing emulsion explosives comprising (a) forming an oil-continuous emulsion at an elevated temperature, (b) incorporating a density reducing agent into the emulsion to sensitize it, (c) packaging the sensitized emulsion into a flexible tubing of desired diameter, (d) cooling the loaded tubing to a desired temperature, and (e) overwrapping the loaded tubing with an additional packaging material.
A method of manufacturing emulsion explosives comprising (a) forming an oil-continuous emulsion at an elevated temperature, (b) incorporating a sensitizing, uniform distribution of gas bubbles into the emulsion to form an emulsion explosive, (c) packaging the emulsion explosive into a continuous flexible tubing of desired diameter, (d) cooling the loaded continuous tubing to a desired temperature, (e) cutting the loaded continuous tubing into individual tubes of desired lengths, and (f) overwrapping the individual tubes with an additional packaging material.
A method of manufacturing emulsion explosives comprising (a) forming an oil-continuous emulsion at an elevated temperature, (b) incorporating a density reducing agent into the emulsion to form an emulsion explosive, (c) packaging the emulsion explosive into a flexible tubing of desired diameter, (d) cooling the loaded tubing to a desired temperature, (e) removing the tubing from the cooled emulsion explosive, and (f) wrapping the cooled emulsion explosive with a packaging material.
A packaged emulsion explosive sensitized by air bubbles wherein the packaging material comprises a cylindrical flexible tube underwrapping and a paper or plastic material overwrapping.
