【 摘 要 】

The electric discharge and mechanical technology of hard rock breakage was developed on the ground of mechanical and electrical pulse methods and it was tested for purposes of deep drilling. It was demonstrated that, due to breakage of the rock surface by electric discharges, the rock excavation volume (breakage performance) is significantly improved as compared to conventional mechanical methods.
