Abstract

An apparatus for position detection in a mine vehicle, a mine vehicle, and a method for monitoring and providing position data in a mining vehicle. The apparatus ( 10 ) comprises one or more sensing devices for generating position sensing data on one or more monitored elements. A control unit (CU) calculates position data in response to the received position sensing data. One or more cameras (11) are implemented as the sensing device. The monitored element is provided with several illuminating spots (12) providing the monitored element with patterns of spots (13). Then the camera generates position data on the several illuminating spots of the spot pattern. Further, the control unit calculates position and orientation of the monitored element in a three dimensional coordinate system.

Abstract

A drill rod (10) for a drilling rig (1) comprises a tube (19) comprising at least one corrugated cut (20) extending through a wall of the tube (19) in a transverse (G) direction. Each corrugated cut (20) has a substantially spiral baseline (21) and is arranged to deviate from its baseline on both sides of the baseline forming a cut of a substantially corrugated shape spiralling along the tube (19). Such tube (19) is flexible enabling bending in a transverse direction (G) of the drill rod (10) and rigid to enable transmitting torque and thrust in a lengthwise (E), transverse (G) and rotational (H) direction of the drill rod (10) when rotated for drilling.
