Abstract: A blast treatment method capable of performing blast treatment of a treatment subject with a simple structure, with high efficiency, and at low cost, while inhibiting scattering of harmful substances or the like to the outside. The method includes: inside disposing an inside explosive for blasting a treatment subject around the treatment subject; disposing an outside explosive having a detonation velocity greater than that of the inside explosive at a position outside the inside explosive; and detonating the outside explosive using an initiation device, and initiating the inside explosive by detonation of the outside explosive, thereby performing blast treatment of the treatment subject by initiation of the inside explosive.

Abstract: Provided is a blast treatment method that enables blast treatment of a treatment subject in a sealed container to be carried out easily and safely. This blast treatment method implements: a shaped charge placement step of placing a shaped charge 70 at a location outside a sealed container 40; a blasting explosive placement step of placing a blasting explosive 20 for blasting a treatment subject 10 at a location outside the sealed container 40; a housing step of housing the sealed container 40 in which the treatment subject 10 is housed in a sealable chamber 90; a dividing step of initiating the shaped charge 70 and dividing the sealed container 40 at prescribed dividing surfaces 40a and 40b with the initiated shaped charge 70 to expose the treatment subject 10; and a blasting step of blast-treating the exposed treatment subject 10 with the blast energy of the blasting explosive 20 by initiating the blasting explosive 20 in the sealed chamber 90.

Abstract: A blast treatment method for blasting a treatment subject having an outer shell and a chemical agent charged into an interior of the outer shell includes the steps of: disposing an explosive on the outer side of the outer shell such that a difference occurs in a detonation pressure of the explosive, that acts on the outer shell from an outer side, between one side and another side of a predetermined cutting position of the outer shell and the outer shell is cut by a shearing force generated as a result of the difference in the detonation pressure; and detonating the explosive, wherein, in the step of detonating the explosive, the chemical agent is exposed by cutting the outer shell in the cutting position through detonation of the explosive, and the chemical agent is decomposed using the detonation.

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.

Abstract: A blast treatment method and an apparatus, which can perform the blast treatment of a treatment subject by using and securely initiating a blasting explosive having fluidity. The blast treatment method includes: a blasting preparation operation of housing a blasting explosive having fluidity in a container and placing the blasting explosive around a treatment subject as well as attaching an initiation device to the container; a housing operation of housing the container, the blasting explosive, and the treatment subject in a chamber; a decompression operation of decompressing the inside of the chamber; and a blasting operation of initiating the blasting explosive and blasting the treatment subject with the blasting explosive. In the decompression operation, the inside of the chamber is decompressed while a gas vent portion regulates the escape of the blasting explosive to the outside of the container and permits the escape of gases in the container to the outside.

Abstract: A blast treatment method for blasting a treatment subject having an outer shell and a chemical agent charged into an interior of the outer shell includes the steps of: disposing an explosive to cover a periphery of the treatment subject; and detonating the explosive from respective end portions of a specific direction toward a predetermined cutting position of the treatment subject between the respective end portions so that detonation waves of the explosive advancing from respective sides of the cutting position collide in the cutting position, wherein, in the step of detonating the explosive, the chemical agent is exposed by cutting the outer shell in the cutting position through detonation of the explosive, and the chemical agent is decomposed using the detonation.

Abstract: Provided is a blast treatment method that can be implemented simply and efficiently blast a treatment subject while preventing fragments of the subject from scattering outward.

The pressure vessel 10, means for achieving the object, has an external vessel 31 and an internal vessel 32 installed in the external vessel 31. The external vessel 31 has a strength for retaining pressure caused by blasting the article. The internal vessel 32 receives fragments of the treated article 100 to protect the external vessel 31 against the fragments. The internal vessel 32 preferably covers almost entire internal surface of the external vessel 31.

Abstract: A method of blasting hazardous substance or explosive in a pressure vessel is provided to improve efficiency while suppressing enlargement of the pressure vessel. To achieve it, the method includes an installing step of installing two or more articles to be treated at a certain spacing in the pressure vessel, an initial blasting step of blasting one of the articles to be treated, and a following blasting step of blasting the article to be treated next to the previously blasted article to be treated after a particular time from the instant of the previous blast. Each of the articles is blasted sequentially through the initial and following blasting steps.
