초록

A method of blasting in reactive ores includes diluting hot liquor of ammonium nitrate with water to provide diluted ammonium nitrate solution of predetermined concentration, adjusting the pH of the liquor of the ammonium nitrate solution, adding a predetermined amount of gassing agent to the ammonium nitrate solution, and emulsifying the ammonium nitrate solution. Then an effective amount of fine zinc oxide powder is mixed with the emulsion explosive and the inhibited emulsion explosive is introduced into a borehole and detonated.

청구항

[ What is claimed is:] [1.] A method of blasting in reactive ores containing sulfide and/or pyrite comprising the steps of:(a) loading a borehole with an emulsion explosive including (1) an emulsifier, (2) a continuous organic fuel phase, (3) a discontinuous oxidizer salt solution phase including water and organic oxidizer salt, and (4) solid phase zinc oxide in an amount greater than about 0.25% of the weight of the composition; and(b) thereafter detonating the emulsion explosive.
