A method and an equipment for controlling the operation of a rock drilling apparatus, which rock drilling apparatus (1) comprises a percussion device (4) for producing impact energy to a tool of the rock drilling apparatus (1), a rotating device (5) for rotating the tool (7) in a drill hole, a feeding device (9) for feeding the tool (7) in the drill hole and a flushing device (11) for supplying flushing agent through the toool (7) and the bit (8) for flushing loose drilling waste from the hole. The feed force (FF) and the percussion power (PP) are determined and the relation between the feed force (FF) and the percussion power (PP) is adjusted to a targeted operation area within an upper and a lower limit.
L'invention concerne un procédé et un équipement permettant de commander le fonctionnement d'un appareil de forage de roche (1) comprenant un dispositif à percussion (4) permettant de fournir de l'énergie de rupture à un outil de l'appareil de forage de roche (1), un dispositif rotatif (5) permettant de soumettre l'outil (7) à une rotation dans un trou de forage, un dispositif d'amenée (9) permettant d'amener l'outil (7) dans le trou de forage et un dispositif de rinçage (11) permettant d'alimenter un agent de rinçage dans l'outil (7) et le trépan (8), aux fins de rinçage des déchets de forage lâches du trou. La force d'alimentation (FF) et la puissance de percussion (PP) sont déterminées et la relation entre la force d'alimentation (FF) et la puissance de percussion (PP) est adaptée en fonction d'une zone de fonctionnement ciblée comprise entre une limite supérieure et inférieure.
