Abstract
A blast treatment method enables easy and safe blast treatment of ammunition having propellant provided with a warhead having a bursting charge and a propulsion unit having a propellant. Comprised are a first explosive arrangement step of arranging a first explosive 70 on the outside of a warhead 11; a second explosive arrangement step of arranging a plurality of explosive members 80 including a second explosive 84 on the outside of the propulsion unit 12; a warhead blast step of causing detonation of a bursting charge 14 by detonation of a first explosive 70, thereby blasting the warhead 11; and a propulsion unit treatment step of causing deflagration of a propellant 18 by detonation of the second explosive 84, thereby performing combustion of the propulsion unit 12; the first explosive 70 is arranged at a position covering the periphery of the warhead 11, a high-pressure field is generated on the periphery of the warhead 11 by detonation of this first explosive 70, and by means of this high-pressure field, divergence of detonation energy of the bursting charge 14 to outside this high-pressure field is suppressed, and moreover the explosive members 80 are arranged at mutually sepa…
