摘要: There are various methods of rock drilling and demolition. Recently, a method utilizing pulsed power technology has appeared. This is based on the difference dynamic breakdown field strength liquid solid dielectrics. The applicability this was examined. features destruction have been studied. mechanism explaining dielectrics with high intrinsic inhomogeneity like natural rocks concrete proposed proved experimentally. An inductive energy storage-opening switch system for materials designed allowing higher efficiency. experimental results using advanced diagnostics such as an image converter camera X-ray computer tomography samples presented. High pulse experiments (up to 60 kT in pulse) conducted.
