FIELD: mining.
SUBSTANCE: method is implemented due to destructing the working face with cross cutters using rotary and planetary disc working members with lower power consumptions and yield of small ore fractions. In order to improve the efficiency of cross cutters, rock-destructing tool of planetary disc members moves in cycloidal-radial directions.
EFFECT: higher efficiency of destructing processes of mine rocks using heading-and-winning machines with cross cutters.
