Abstract (en)
The invention relates to a rock drilling rig and a method of positioning a rock drilling unit. The rock drilling rig (5) is provided with a detection device (4) for detecting a reference line (RL), such as a previously drilled drill hole fan (1). The detection device is positioned in the direction of gravity (G). The position and direction of the detected reference line are utilized when positioning a drilling unit to a new drilling position at a predetermined horizontal reference distance (RD) from the reference line.
