ABSTRACT:
A method of minimizing deep hole pressure effects on ammonium nitrate-containing blasting agents while optimizing booster sensitivity, detonation rate and detonation energy of such agents, by replacing density control component(s) with a sensitizer formulation comprising particulate aluminum and particulate smokeless powder; and a corresponding detonatable high density emulsion blasting agent utilizing such sensitizing formulation.
