BLASTING METHOD AND BLASTING DEVICE

摘要

Provided are 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 of the invention includes: a blasting preparation step of housing a blasting explosive 30 having fluidity in a container 20 and placing the blasting explosive 30 around a treatment subject 10 as well as attaching a initiation device 50 to the container 10; a housing step of housing the container 20, the blasting explosive 30, and the treatment subject 10 in a chamber 60; a decompression step of decompressing the inside of the chamber 60; and a blasting step of initiating the blasting explosive 30 and blasting the treatment subject 10 with the blasting explosive 30. In the decompression step, the inside of the chamber 60 is decompressed while a gas vent portion 26 regulates the escape of the blasting explosive 30 to the outside of the container 20 and permits the escape of gases in the container 20 to the outside.
