PROBLEM TO BE SOLVED: To produce such a compsn. that the explosion rate is increased and that the power to destruct a rock and the gas produced by firing are significantly improved, by heating a mixture of an oxidizing agent essentially comprising ammonia nitrate, fuel and a potassium compd. at specified temp. during mixing and/or after mixing. SOLUTION: An oxidizing agent containing at least one ammonia nitrate selected from porous granular ammonium nitrate, pulverized porous ammonia nitrate, powdery ammonium nitrate, etc., by >80wt.% is mixed by 84 to 97wt.% of the whole compd. with a potassium compd. having <=80μm particle size selected from potassium sulfate, potassium nitrate, potassium benzoate, potassium sorbate, etc., by 0.5 to 5wt.% of the whole compsn. Then at least one fuel which is liquid at normal temp. and selected from light oil, kerosine, dinitrotoluene, dinitroxylene, alcohols, nitroporopane, etc., is added by 3 to 10wt.% of the whole compsn. During mixing the explosive compsn., and/or after mixing, the mixture is heated at about 32.5 to 150 deg.C so as to stably obtain safety in the production process.
