FIELD: mining.
SUBSTANCE: drive element operates in the direction (R). The method comprises stages at which: a drive head with axis of rotation is provided for connecting to the drill string means. The drive head is arranged for joint operation with feeding element operating respectively in a first (P) and a second (P') direction; the drive head is rotatable relative to the support device of the drive element and the feed element about the axis of rotation (A) extending in transverse direction with respect to said direction (R); the drive head is rotated from the first fixed end position, in which the axis of drive head rotation is parallel to the said direction (R), and the feeding element drives the drive head in the first direction (R) into the second fixed end position, in which the axis of drive head rotation is parallel to said direction (R), and the feeding element drives the drive head in the second direction (P'). Directions (P) and (P') are opposite. Invention also relates to the drilling structure and a computer-readable carrier comprising a program code for electronic control unit connected to the drilling structure for implementing the method.
EFFECT: reduced dimensions of the drilling structure.
