A method for sucking dust in connection with a rock drilling rig, and a rock drilling rig. The rock drilling rig ( 1 ) comprises a dust collection system provided with a suction device ( 11 ) to produce suction for sucking dust from a drill hole ( 8 ) through a first suction channel ( 12 ). The rock drilling rig further comprises a second suction channel ( 17 ) allowing the suction effect of the dust collection system to be utilized for sucking dust from a location other than the drill hole, for example from the control cabin ( 15 ). Exhaust suction is controlled by means of a control unit ( 26, 48 ).
