FIELD: drilling equipment engineering. ^ SUBSTANCE: device has vehicle, beam mounted fixedly relatively to the latter, to which a drilling assembly is fixed containing at least a drilling hammer, feeding bar and feeding means. Device has at least one case for storing drilling elements used during drilling and block for replacing drilling elements providing for their transfer between case for storing drilling elements and drilling assembly. Case for storing drilling elements is mounted on vehicle or on beam separately from drilling assembly, while device also has means for transferring drilling assembly to given position and given placement relatively to case for storing drilling elements or replacing drilling element. ^ EFFECT: simplified construction, higher reliability, optimal dimensions. ^ 8 cl, 4 dwg |
