BLAST TREATMENT METHOD AND BLAST TREATMENT DEVICE

摘要

A blast treatment method capable of more reliably treating an object to be treated which is accommodated in an outer container is provided. The blast treatment method includes: a step for spacing a plurality of blasting explosives (20) from one another at positions on the outer side surface of an outer container (60) in a direction surrounding a central axis (C2) of the outer container (60) and arranging the blasting explosives (20) in such a manner as to extend approximately parallel to the central axis (C2); a step for installing the outer container (60) within a chamber (90); and a step for detonating the blasting explosives (20) within the chamber to perform blast treatment of an object (10) to be treated with the detonation energy, wherein the blasting explosives (20) are detonated at the blast timing at which fragments of the outer container (60) or shock waves, which are generated in the vicinity of the blasting explosives (20) by the detonation energy of the blasting explosives (20), collide with or propagate to a bombshell (10) in less time difference than that in the case in which the plurality of blasting explosives (20) are detonated at the same time.
