2. Description of the Related Art A large number of ammunition shells originally manufactured for war are still unused all over the world. However, it is safe and quick to dismantle such shell shells. It is desired to process. Traditionally,
As a method for safely processing shells containing explosives such as TNT explosives, a method has been proposed in which holes are made in the shells to inject a predetermined chemical, and the TNT explosives are melted and solidified to be safely recovered. (See Japanese Patent Laid-Open No. 7-253300).

However, chemical weapons containing harmful chemical substances are also mixed in the shells, and it is necessary to safely disassemble and process such chemical weapons. When treating such chemical weapons, it is important not to mix the explosive charge and the chemical substances contained therein. This is because if a chemical substance is mixed in the explosive, toxic gas may be generated or toxic waste may be generated when the explosive is treated by burning or neutralization, which is very dangerous. However, with the conventional method of dismantling a cannonball, it was difficult to safely process a cannonball containing a chemical substance without mixing the explosive charge and the chemical substance.

Therefore, an object of the present invention is to provide a cannonball dismantling method capable of safely dismantling and treating even a cannonball containing a chemical substance.
