An apparatus, a method for positioning a rock drilling, and a rock drilling rig is provided. The rock drilling rig includes a mobile drilling platform and a drilling mast connected to the drilling platform. The drilling platform is levelled vertically before initiating drilling. The apparatus determines the needed vertical levelling requirement. The levelling causes displacement of a drilling tool line passing through a drilling tool. The apparatus estimates the displacement and provides aid for the operator to position the drilling platform in order to compensate for the estimated displacement distance.

Apparatus and method for positioning rock drilling rig

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.

Dynamic working area

A rock drilling apparatus and method for controlling the orientation of a feed beam of a rock drilling apparatus including a carrier, a drilling boom attached at a first end to the carrier, a feed beam attached turnably to a second end of the drilling boom, a drilling unit attached movably along the feed beam, and a support attached to the feed beam for supporting the drilling boom on the ground. The orientation of the boom and feed beam are adjusted to compensate for the orientation change caused by driving the support onto the ground.

The disclosure relates to a mining vehicle and a method of moving a boom of a mining vehicle. The boom is provided with several boom joints and there is a mining work device at a distal end of the boom. One or more boom joint positions are determined and stored in a memory medium. A control unit of the mining vehicle may automatically move the boom to a predetermined transport position.
