The present invention relates to an emulsion composition for an explosive and to a method of preparing the same, wherein the emulsion composition includes, based on the total weight thereof, 85 to 95 wt % of an oxidizing agent aqueous solution, 0.3 to 5 wt % of an emulsifier, and 3 to 10 wt % of oil, the emulsifier including a PIBSA (polyisobutylene succinic anhydride) amine salt having an acid value of 30 or less and an amine value of 45 to 65, under a precondition that the oxidizing agent aqueous solution includes at least one of industrial ammonium nitrate, agricultural ammonium nitrate and low-specific-gravity ammonium nitrate for an ammonium nitrate fuel oil explosive, which is used without additional filtration or removal of impurities.
An emulsion composition for an explosive, comprising an oxidizing agent aqueous solution including, as granular ammonium nitrate added with an organic or inorganic material including a phase-transition inhibitor, a solidification inhibitor or a coating agent, at least one of agricultural ammonium nitrate, porous ammonium nitrate for an ammonium nitrate fuel oil explosive and high-specific-gravity ammonium nitrate, and a fuel solution including an emulsifier and an oil,
A method of preparing an emulsion composition for an explosive, the method comprising:
