PROBLEM TO BE SOLVED: To obtain an explosive composition improved in the detonation reaction rate and the generation of gas after blasting by uniformly mixing an oxidizing agent composed mainly of ammonium nitrate with a fuel and a potassium compound. SOLUTION: This explosive composition contains an oxidizing agent composed mainly of ammonium nitrate, a fuel and a potassium compound and has fine crystals containing 111-phase ammonium nitrate on the surface of particle. The fine crystal is an acicular or dendrite crystal having a longitudinal length of about 1-200μm. The explosive composition is produced e.g. by mixing an oxidizing agent composed mainly of ammonium nitrate with a fuel and adding a potassium compound to the mixture or adding a mixture of a fuel and a potassium compound to an oxidizing agent composed mainly of ammonium nitrate. The preferable oxidizing agent is porous granular ammonium nitrate, crushed porous ammonium nitrate, powdery ammonium nitrate, etc. The potassium compound is preferably potassium sulfate, potassium nitrate, potassium sorbate, potassium benzoate, potassium acetate, etc.
