Applying High Voltage Pulse Discharge in Rock Blasting: Theoretical Problems
Using high voltage pulse discharge to blast rock is a kind of non-explosive blasting method which generates explosions from electrical discharges. Comparing with explosive blasting,this developing technology is demonstrated to be well-controlled and environment-friendly to fracture rock and concrete,and it is particularly suitable for application in complex environments. However,due to lack of systematic reSearcheS,many theoretical problems of applying high voltage pulse discharge in rock blasting still remain unsolved. The purpose of this paper is to summarize and analyze these problems encountered in recent researches.including process of discharge-induced explosion,explosion-induced shock pulse-pressure in liquid media,process of dynamic fragmentation and rock fragmentation mechanism,and discuss the ways to solve them. Future trends in this research area are presented from four aspects.
