ABSTRACT:
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.
