Oettmeier, B W; Porter, S J

A sensitive gas-entrained water gel explosive is made by mixing at a location convenient to the blasting site a concentrated aqueous solution of ammonium nitrate, nitric acid, sodium nitrate, hexamethylenetetramine and a minor amount of a thickening agent such as guar gum. Sufficient time is allowed for the gum to become hydrated to attain the maximum thickening effect.The resulting thickened solution is mixed with solid ammonium nitrate and a minor amount of a fuel to yield a thickened slurry. Then, there is injected into the thickened slurry both a substantial quantity of a gas and a solution which has the effect of cross-linking the thickening agent. The resulting thickened slurry is mixed thoroughly by passing through a static mixer. (4 claims)
