    • PROBLEM TO BE SOLVED: To obtain an explosive compsn. having excellent fluidity for the process of packaging the explosive, sensitivity and power for use and high packing density in simple production processes by mixing an aromatic dinitro compd. which is liquid during mixing to a mixture having specified proportions of plural kinds of porous prill ammonium nitrate each having specified average particle size and oil absorption. SOLUTION: A mixture of 20 to 80wt.% porous prill ammonium nitrate having 0.01 to 1.0mm average particle size and 8 to 14% oil absorption and 80 to 20wt.% porous prill ammonium nitrate having 1.0 to 3.0mm average particle size and 15 to 22% oil absorption is prepared, to which an aromatic dinitro compd. (such as dinitrotoluene) in a liquid state during mixing is added preferably at 35 to 160 deg.C, more preferably at 50 to 100 deg.C to obtain the explosive compsn. The explosive compsn. contains by wt.%, 30 to 99% porous prill ammonium nitrate, preferably 70 to 96%, and 1 to 50%, aromatic dinitro compd., preferably 4 to 30%.
