Abstract

The present invention relates to a method and a device for controlling at least one drilling parameter when drilling into rock with a drilling machine, where a percussion pressure and/or a feed pressure of the drilling machine, which generate a percussive force and a feed force respectively, are controlled during the drilling operation. A parameter value is determined that represents the mean value of a damping pressure in a damping chamber used both for transmitting a feed force to a drill string that is connected to the drilling machine, and for damping rock reflections from this drill string; a difference between the said mean value of the determined damping pressure and a reference value of the damping pressure is also determined. The percussion pressure and/or the feed pressure of the drilling machine is then controlled on the basis of this difference.
