FIELD: mining.
SUBSTANCE: invention relates to mining plows used with mine machines for long cleaning faces. Mining plow comprises a plow body constructed to be guided at a conveyor, a first cutting bit carrier pivotably supported on a first pivot pin, a second cutting bit carrier pivotably supported on the second pivot pin, a central roof cutting bit carrier assembly at least partially arranged between the first cutting bit carrier and the second cutting bit carrier, and a pushrod displaceably arranged within the plow body. Plow body includes a first end with a first pivot pin and a second end with a second pivot pin, the second end opposing the first end. Pushrod forms a coupling between the first cutting bit carrier and the second cutting bit carrier, the pushrod being arch-shaped to pass around the central roof cutting bit carrier assembly.
EFFECT: reduced wear of the pushrod and the preservation of the narrow profile of the plow.
