Abstract

FIELD: mining; applicable in breakage of rocks by pulse action. SUBSTANCE: device for breakage of frozen mass consists of high-frequency vibropack made in form of ring with rectangular cross-section. Percussive member of low-frequency vibrator is located in ring hollow. The device also includes feedback vibration transducer and voltage and power amplifiers. Method for breakage of frozen ground consists in that simultaneously with high-frequency action on mass with frequency equalling frequency of vibration of rock mass on covibrating mass, low frequency stimulation is effected. EFFECT: reduced energy consumption in breakage of frozen rock mass. 2 cl, 1 dwg
