Called E lectroH ydraulic F racturing (EHF), our technology uses just a small amount of a nontoxic liquid electrolyte which transforms into a containable plasma, shortduration highpower electrical pulses, and a patented blasting tip to create calculated precise discharges into rock or concrete fracturing. No jack hammering, explosives, loud ...
Power increases as time passes. Although fragmentation takes place within 12 to 24 hours, the progressive action of Bustar expansive grout continues for four days in summer and eight days in winter reaching a pressure of over 7000 T/m2 (rock and concrete break at between 1500 and 3000 T/m2).

The investigation of possibilities of the plasma blasting technology is considered. The method is based on the initiation of a pulsed electric discharge inside the solid dielectric material. The expanding plasma channel generates a shock wave which in the vicinity of the channel (1–2 mm) transforms into the elastic wave with an expressed region of tensile tangential stresses that in turn ...
