Abstract
A blasting cartridge includes a generally cylindrical blasting container, a blasting substance filled in the blasting container, a pair of leadwires contained in the blasting container, and a single thin metal wire connected to tip portions of the pair of leadwires. The leadwires and the thin metal wire are positioned within the blasting substance within the blasting container. The blasting substance is nitromethane, and the thin metal wire is formed of tungsten. With an electric discharge impact blasting apparatus, since the thin metal wire has a higher heating value than a copper wire because of its higher resistance and vaporizes at higher temperatures, it is possible to obtain a greater blasting force at lower voltages than with a blasting apparatus using a copper wire.
