摘要： A method and an apparatus for monitoring the operation of a percussion device, which percussion device (1) comprises a percussion piston (3) and a pressure channel (5) for supplying pressure medium to the percussion device (1) for moving the percussion piston (3). The method and the apparatus measure pressure pulsation of the pressure medium acting in the pressure channel (5), which pressure pulsation is depicted as a pressure curve (10). From pressure pulsation are determined parameters depicting the operating state of the percussion device (1) and the operating state of the percussion device (1) is determined on the basis of said parameters.In addition, an arrangement for controlling the operation of the percussion device on the basis of the operating state of the percussion device (1).

摘要： 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.

摘要： The invention relates to a hydraulic system for mining equipment and to a method of adjusting the power of a rock drill machine. At least one mining actuator (13, 14, 15) used for detaching rock is connected to a dedicated separate hydraulic circuit (30, 31, 32) comprising a special hydraulic pump (7, 8, 9). The power of said mining actuator is adjusted by changing the hydraulic power generated by the separate hydraulic circuit of the hydraulic pump.
