Description

FIELD OF THE INVENTION

[0001] The invention relates to a method for controlling power consumption during a rock drilling process of the kind defined in the preamble of claim 1.

[0002] The invention further relates to a system and a rock drilling apparatus of the kind defined in the preamble of claims 11 and 21, respectively. BACKGROUND OF THE INVENTION

[0003] Rock drilling apparatuses may be used in a number of fields. For example, rock drilling apparatuses may be used in tunnelling, underground mining, rock reinforcement, raise boring, and for drilling of blast holes, grout holes and holes for installing rock bolts.

[0004] Rock drilling is often performed by percussion rock drilling, in which a drill tool mounted at one end of a drill rod is provided with impact pulses by a hammer piston, arranged on the opposite side of the drill rod, and arranged to be powered to repeatedly impact upon the drill rod. At the outermost end of the drill tool there are drill bits that penetrate the r...
