A method for automatically guiding a mining machine ( 14 ) provided with a route determined as successive route determined as successive route points in the mine. In the method, data relating to the successive points are used for determining additional route between the successive route points for guiding the mining machine ( 14 ).

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 i...

A method of initializing the position and direction of a mining vehicle, and a mining vehicle. An environmental model and route points are stored in a control system of the vehicle. The environment of the vehicle is scanned, and scanned points are generated based on obstacles observed. The control system is arranged to determine coordinates of the scanned points by using the position of the route ...

A mine vehicle and a method of preventing a mine vehicle from colliding. The mine vehicle (1) includes at least one scanner (13, 14) to scan the environment in front of the vehicle. On the basis of the scanning, an obstacle-free route is determined whose outermost points in a sideward direction are stored as memory points (21).
