FIELD: mining.
SUBSTANCE: drill rig is frameless and comprises the first manipulator link and the second manipulator link, between which there is a connecting accessory that provides for manipulator links movement relative to each other. A support at a rock is connected to the connecting accessory for resting against the rock after rough positioning of the drilling line near the line of blast holes. Accurate positioning of the drilling rig along with the direction of the blast holes line is arranged by means of joints available in the connecting accessory. Positioning onto the blast holes is carried out by rotation of the second manipulator link along the arched trajectory and by rotation of a drilling unit towards the rock to be drilled.
EFFECT: accurate manipulator positioning.
