FIELD: mining.

SUBSTANCE: device for pre- destruction of rocks refers to devices designed for continuous pre-fracture of soft and medium-hard rocks and minerals of categories V-VII on the scale of prof. MM. Protodyakonov in the inclined plane of the slope of benches, including high benches during open-pit mining. The device for pre-destruction of rocks consists of a self-propelled chassis with a rotary table placed on it with control equipment and a disk working element installed with the possibility of vertical movement. The working body is made in the form of leading and trailing shafts, located parallel to each other, with evenly spaced cutting discs attached to them. The opposing cutting disks of the shafts are located in the same plane. The diameter of the cutting disks on the leading shaft is less than the diameter of the cutting disks on the trailing shaft. The leading and trailing shafts with cutting disks are spaced apart and installed at the ends of the self-propelled chassis, respectively.

EFFECT: increased performance and reliability of the device.
