Abstract: 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). At least one sideward safe area (15b) has been predetermined around the vehicle (1). A control system checks that no memory point (21) resides within the safe area (15b).

Abstract: A method and an apparatus for determining the position of a mining machine as its wheels skid with respect to the underlying surface. In the method, at least one detector detecting the operation of transmission detects skidding of at least one wheel with respect to the underlying surface, whereupon determination of the position by means of the rotation of the wheels and the direction of travel is interrupted. The apparatus includes at least one detector for detecting the operation of the transmission, the detector detecting the skidding of at least one wheel with respect to the underlying surface.

Abstract: The invention relates to a method and an apparatus for determining position of a mining machine as its wheels skid with respect to the underlying surface. In the method, at least one detector detecting the operation of transmission detects skidding of at least one wheel (2c) with respect to the underlying surface, whereupon determination of the position by means of the rotation of the wheels (2c) and the direction of travel is interrupted. The apparatus comprises at least one detector for detecting the operation of the transmission, the detector detecting the skidding of at least one wheel (2c) with respect to the underlying surface.
