Method for controlling power consumption during a rock drilling process with a rock drilling apparatus, wherein the rock drilling apparatus includes main power supply means for supplying power for the rock drilling process, which includes at least the sub-processes of percussion and/or rotation and flushing, the method comprising the steps of: - adjusting the flush power at least partly as a function of hole depth, and controlling at least the percussion power and/or rotational power and the flush power such that the total power consumption of each sub-process is controlled.
L'invention concerne un procédé pour le contrôle de la consommation d'énergie en cours de forage de roches, avec dispositif de forage correspondant comprenant un système d'alimentation principal utilisé durant l'opération. Le procédé comprend au moins des opérations secondaires de percussion et/ou de rotation et de rinçage, selon les étapes suivantes : réglage de la puissance de rinçage au partiellement en fonction de la profondeur du trou, et contrôle portant au moins sur la puissance de percussion et/ou de rotation et la puissance de rinçage, de sorte que la consommation d'énergie totale de chaque opération secondaire soit contrôlée.
