Beschreibung
Zusammenfassung:	Rock drilling apparatus and method for controlling the orientation of a feed beam (7) of a rock drilling apparatus comprising a carrier (1), a drilling boom (2) attached at a first end to the carrier (1), a feed beam (7) attached turnably to a second end of the drilling boom (2), a drilling unit (5) attached movably along the feed beam (7), and a support (8) attached to the feed beam (7) for supporting the drilling boom (2) onto the ground. The orientation of the boom (2) and feed beam (7) are adjusted to compensate for the orientation change caused by driving the support (8) onto the ground.
