Abstract
A method for defining a working area of a rock drilling rig including the steps of determining at least one current input parameter, determining a working area that defines a reach of the drilling unit in a control unit on the basis of the at least one current input parameter and at least one fixed reach parameter, displaying a graphical representation of the working area on a display, and re-determining the working area and updating the graphical representation of the working area dynamically in response to a change in the input parameters. The current input parameter may be, for example, an orientation of the rock drilling rig or a hole parameter.

A method for defining a working area of a rock drilling rig, the method comprising the steps of:
- providing a rock drilling rig including a movable carrier, at least one boom pivotally disposed on the carrier, a drilling unit arranged on the boom, at least one control unit and at least one display device connected to the control unit, the drilling unit including at least one rock drilling machine and a tool;
- determining at least one current input parameter that is variable during operation of the rock drilling rig, the at least one current input parameter being selected from a current orientation of the rock drilling rig with respect to a predefined drilling plan and a position and direction of at least one hole planned to be drilled in the predefined drilling plan without moving the rock drilling rig;
- determining a working area according to the predefined drilling plan, that defines a reach of the tool of the drilling unit arranged on the boom and boundaries of the movement range of the tool, in the control unit on the basis of said current orientation of the rock drilling rig, according to said position and direction of at least one hole planned to be drilled and according to at least one fixed reach parameter;
- re-determining said working area and updating said graphical representation of said working area dynamically in response to a change in said orientation of the rock drilling rig or in said direction of at least one hole planned to be drilled;
- and
- displaying a graphical representation of said working area on the display by indicating one or more holes planned in the predefined drilling plan that can be drilled from a current position of the rock drilling rig without moving the rock drilling rig.
An arrangement for a rock drilling rig, the arrangement comprising:
- means for determining at least one current input parameter that is variable during operation of the rock drilling rig, the at least one current input parameter being selected from a current orientation of the rock drilling rig with respect to a predefined drilling plan and a position and direction of at least one hole planned to be drilled without moving the rock drilling rig;
- at least one control unit configured to determine a working area according to the predefined drilling plan and defining a reach of a tool of the drilling unit and boundaries of the movement range of the tool on the basis of said current orientation of the rock drilling rig, according to said position and direction of at least one hole planned to be drilled and according to at least one fixed reach parameter;
- re-determining said working area and updating said graphical representation of said working area dynamically in response to a change in said orientation of the rock drilling rig or in said direction of at least one hole planned to be drilled;
- and
- at least one display configured to display said working area by indicating one or more holes planned in the predefined drilling plan that can be drilled from a current position of the rock drilling rig without moving the rock drilling rig.
A user interface of a rock drilling rig comprising at least one display, wherein the display is configured to display a working area of a rock drilling rig as a graphical representation determined on the basis of a current orientation of the rock drilling rig with respect to a predefined drilling plan and a position and direction of at least one hole planned to be drilled in the predefined drilling plan without moving the rock drilling rig, wherein the working area is defined by the predefined drilling plan that defines a reach of a tool of a drilling unit of the drilling rig, said graphical representation of said working area indicating one or more holes planned to be drilled in the predefined drilling plan from a current position of the rock drilling rig without moving the rock drilling rig and thus the boundaries of the movement range of the tool, and wherein said graphical representation is updated dynamically in response to a change in at least one current input parameter that is variable during operation of the rock drilling rig, the at least one current input parameter being selected from said orientation of the rock drilling rig or said direction of at least one hole planned to be drilled.
