BLASTING CARTRIDGE, BLASTING APPARATUS, AND BLASTING METHOD

摘要

A blasting cartridge (2) is provided with a roughly-cylindrical demolition container (21), a demolition substance (22) which is filled in the demolition container (21), a pair of conductive wires (23) which is housed in the demolition container (21), and one thin metal wire (24) which is connected to each tip portion (231) of the pair of conductive wires (23). The conductive wires (23) and the thin metal wire (24) are placed in the demolition substance (22) in the demolition container (21). The demolition substance (22) is nitromethane and the thin metal wire (24) is formed with tungsten. The thin metal wire (24) has a greater resistance compared to copper wires thereby generating large amounts of heat, and has a high temperature when being vaporized. Therefore, compared to demolition devices using copper wires, a discharge impulse demolition device (1) can produce a greater destructive force with low voltage.
