Abstract:
A method and a control system for positioning a mine vehicle. Measurement of a distance travelled by the mine vehicle is based on monitoring rotation of a wheel. In the invention, an error caused in the distance measurement by wear of the wheel is compensated for automatically when the distance value obtained from monitoring is corrected by a correction factor. The value of the correction factor is updated at predetermined intervals during use.
