Abstract: In this article we presented mathematical model and geometrical and frequency parameters calculation of pulse generator node, which built into the work instrument for rock breaking by combined rotary-hydroсavitation method. The developed method allows to use specific energy of cavitation flow which reaching 10^4 ... 10^5 kWh/m^3 . Permanent magnets used for axial focusing of cavitation flow in the body of work instrument. Due to magnets’ action occurs oscillations cavities interference. As a result, cavitation’s frequency increase to subresonance. Subresonant flow creates additional stress on rock. Natural and artificial fractures formed, rocks’ resistance to cutting reduce, rock breaking energy reduce by 10% .
Key words: destruction, method, rock, frequency, cavitation.
