Patent ID: 8464808

Claim:
Method for controlling a drill rig which includes a carrier vehicle with at least one feed beam, whereon a drill machine is movable to-and-fro, wherein rig parameters are set by a control unit and wherein each one of a plurality of operating modes includes specified operating settings for different operating parameters of the rig, wherein each operating mode is selectable such that operation of the rig is related to a particular type of rock, in which drilling is to be performed, wherein each operating mode includes operating settings that are adapted to the prevailing type of rock, wherein rock condition is selected, whereby one or more of the following parameters varies as a function of rock condition: feed pressure, percussion pressure, damping pressure, wherein bit size is selected, whereby one or more of the following parameters varies as a function of bit size: flushing flow, rotation speed, feed pressure, percussion pressure, ratio feed force-rotation torque relation, starting point for initiating anti-jam function, and wherein rod size is selected, whereby one or more of the following parameters varies as a function of rod size: percussion pressure, feed motor pressure, wherein activation of one operating mode also sets the parameter values for, activates or de-activates drilling control functions, being one or more from the group; boost, hole flushing, pressure control of feed, flow control of feed, anti-jam function, damping control function, super rotation, feed speed control of percussion pressure.
