Abstract: Proposed is an emulsion explosive composition containing 80% to 95% by weight of an oxidizing agent aqueous solution containing hydrogen peroxide, nitrate, and diethylene triamine penta(methylene phosphonic acid) (DTPMPA), 0.1% to 10% by weight of an emulsifier, and 2% to 15% by weight of an oil. The emulsion explosive composition can effectively solve self-gassing problems caused by a reaction between hydrogen peroxide and nitrate.

Abstract: The present disclosure provides an emulsion explosive composition for a booster of a bulk explosive. The composition contains 88% to 98% by weight of an oxidizer aqueous solution, 0.1% to 6% by weight of an emulsifier, 0.1% to 5% by weight of fuel oil, and 0.1% to 1.0% by weight of plastic micro balloons (PMB). The oxidizer aqueous solution is an oxidizer aqueous solution containing ammonium nitrate, sodium nitrate, calcium nitrate, water, and at least one selected from monomethyl amine nitrate (MMAN) and ethylene diamine dinitrate (EDDN). The prepared emulsion has a particle size in the range of 0.5 μm to 2.0 μm.
