CO-AXIAL TYPE REACTION ASSEMBLY FOR PLASMA BLASTING

摘要

A coaxial type reaction assembly for plasma blasting that can reduce size of required drilling diameter by improving a conductor connecting structure as a coaxial type, reduces construction period and construction cost by exhibiting more enhanced blasting power through minimization of blasting power loss due to a decoupling effect, and obtains a reduction effect of manufacturing cost by simplifying the manufacturing process of an impact cell is provided. A coaxial type reaction assembly for plasma blasting comprises: a paper tube(100) for forming a sealed internal space; an inner conductor(300) that passes through a central part of the paper tube in an axial direction; an insulator(400) for surrounding an outer peripheral surface of the inner conductor; an outer conductor(200) for surrounding an outer peripheral surface of the insulator; and an electrolyte(500) filled in a sealed internal space between the outer conductor and the paper tube. The outer conductor is made of a metal foil that is a thin metal sheet. The metal foil has a plurality of nonconductor gaps formed thereon. The metal foil has a plurality of perforated holes formed thereon. The electrolyte is metal and metal oxide.
