Rock Fracturing by Plasma Blasting Technology
Newly developed compact blasting equipment it suitable for blasting of platy structures and boulder stones. Holes for blasting can be opened by hand-held tools. Therefore, the blasting procedure is easy and simple. By creating more than one hole in linear orientation and discharge at the same time, the object can be blasted as if it were cut.
