The invention relates to a rock drilling rigand a method of drilling rock. The rock drilling rig (2) comprises a flushing system with two or more compressors (9a, 9b) for generating the required compressed air for the flushing. The flushing air is conveyed along a flushing duct (11) to a rock drill machine (5) and further along a tool (12) into a drill hole (10). The rock drilling rig comprises a driving engine (8) arranged via a transmission device (16) to operate the compressors. Transmission to one or more compressors can be disconnected when the need forflushing air is small.
