FIELD: mining. ^ SUBSTANCE: invention is related to mining industry and may be used in boring-shearing combines for rock breaking with cutting tool. Method for breaking of massif with cross cuts of certain depth made with rotor and planetary-disk actuators. When using combined breaking element: cuts of planetary-disk actuator are arranged in radial direction, and cuts of rotor actuator in tangential one in the form of concentric circumferences. At the same time depth of rotor element cuts is equal to depth of planetary element cuts in the areas of cuts crossing. ^ EFFECT: reduced power inputs and yield of fine rock fractions in process of massif breaking with combine actuators. ^ 2 cl, 4 dwg |
