FIELD: mining engineering.
SUBSTANCE: method includes cutting of inclined slots on a slope and horizontal slots on a working platform by a working member of a disc-cutting excavator with milling cutters installed parallel to each other. Independent periodic and asynchronous superposition of oscillations to each of the milling cutters is carried out separately by means of vibration mechanisms, which frequency and amplitude oscillations are transferred depending on inclination angle of a telescopic rod, directions of cutting force by the milling cutters and physico-mechanical properties of rock controlled by sensors of automatic process control system and control of working systems of the disc-milling excavator. The adjustment of the milling cutters positioning with respect to each other is carried out along the guides by means of hydraulic mechanism.
EFFECT: increased performance, reliability and process efficiency of frozen rock softening.
