A control apparatus for controlling a multi-phase rock drilling event carried out with a rock drilling rig. In a display of the rock drilling rig or a control unit thereof, a first section is settable for substantially invariable information sources and a second section for information sources to be changed according to the rock drilling situation. Further, a situation-specific rock drilling definition is set in the control apparatus about at least one information source, information relating to which is to be displayed during the rock drilling situation. The working phase of the rock drilling event is checked, and an information source suitable for the phase is selected on the basis of the definition. Information relating to the at least one selected information source is displayed in the display part during execution of the rock drilling phase.

Adaptive user interface for rock drilling rig

The rock drilling rig comprises a first control unit () arranged on a carrier () and a second control unit () arranged to a rock drilling apparatus (). The first control unit () and the second control unit () communicate with each other by means of a first data communications link (). The rock drilling apparatus () has one or more sensors (), the measuring results of which are processed in the second control unit () and only then transmitted to the first control unit () that controls actuators regulating the operation of the rock drilling apparatus (). Correspondingly, the rock breaking machine, such as a breaking hammer, comprises one or more sensors () and a control unit ().

Rock drilling rig and rock breaking machine

A method and a control system for controlling rock drilling. A control unit of a rock drilling apparatus is provided with one or more control modes, each determining the drilling variables to be measured, their threshold values and the operating principles according to which the operating parameters of drilling are controlled to achieve a desired control criterion.

Drilling control arrangement

A method and an equipment for controlling the operation of a rock drilling apparatus, which rock drilling apparatus comprises a percussion device for producing impact energy to a tool of the rock drilling apparatus, a rotating device for rotating the tool in a drill hole, a feeding device for feeding the tool in the drill hole and a flushing device for supplying flushing agent through the tool and the bit for flushing loose drilling waste from the hole. The feed force and the percussion power are determined and the relation between the feed force and the percussion power is adjusted to a targeted operation area within an upper and a lower limit.
