    • PROBLEM TO BE SOLVED: To provide a semicontinuous process for obtaining a composite explosive powder containing a solid polyurethane matrix packed with an explosive. SOLUTION: Provided is a production process comprising a step of preparing a pasty explosive composition by the continuous mixing of a pasty component A' discontinuously prepared from a polyol prepolymer, 1 to 10 wt.% portion of a polyisocyanate monomer, a plasticizer, and a pulverulent solid explosive comprising at least one nitro-organic explosive with a liquid component B' comprising the remaining 90 to 99 wt.% portion of the polyisocyanate monomer, a step of introducing the pasty explosive composition into a mold, and a step of thermally crosslinking the composition in the mold, wherein the continuous mixing of the component A' with the component B' is practiced under such conditions that the component A'/component B' weight ratio is constant and lies in the range of 95.05/4.95 to 99.55/0.45.
