摘要： The invention relates to a method and a rock-drilling rig for drilling a hole in a rock. In the method the hole is drilled with a so-called top-hammer rock-drilling rig including a drill rod and a cone roller bit at the end of the drill rod. During drilling with the percussion device, stress pulses of low amplitude are produced at a high frequency of at least 200 Hz. In the rock drilling rig, the cone roller bit (3) at the end of the drill rod and the percussion device are configured to feed stress pulses of low amplitude, at the frequency of at least 200 Hz, via the drill rod and the cone roller bit to the rock.

摘要： The invention relates to a method and software product for controlling a percussion device belonging to a rock-drilling machine, and to a percussion device. The impact frequency of the percussion device (7) is set so that the percussion device (7) forms a new compression stress wave (p) to the tool (8) always when reflected waves (h) from the previous compression stress waves reach a first end (8a) of the tool. This requires that the impact frequency be set proportional to the propagation time of the stress wave, whereby the length of the used tool (8) and the propagation velocity of the stress wave in the tool material are to be noted.
