Abstract: A method for arranging automatic control of a mobile mining machine equipped with a bucket is disclosed. The method generates a general purpose bucket emptying model that defines at least the path of the bucket of the mining machine for emptying it. The bucket emptying model is stored on a memory. The bucket emptying model is fetched from the memory in response to a need to define emptying the bucket for the route. At least data defining the path of the bucket in the fetched bucket emptying model are appended to the path data for use in the automatic control of the mining machine.

Abstract: A method and a system for monitoring the location of a mining vehicle in a mine. The mine includes a first and a second work area. At least one identifier whose exact location is known is arranged in the first work area. The location of the mining vehicle is determined continuously by use of a dead reckoning. The location data, based on the dead reckoning, can be updated by use of the identifier. The location data are transmitted to a mine control system for monitoring the mining vehicle.

Abstract: A method and a system for monitoring the location of a mining vehicle in a mine. The first mine section (18) is provided with a wireless network (10) for data transmission between the mining vehicle (1, 1a, 1b) and the mine control system (11). In addition, the network is used for positioning. In the second mine section (21), the location is determined by means of measuring devices provided in the mining vehicle.

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.

Abstract: A method and system for stopping an unmanned mine vehicle in a predetermined position. The mine vehicle is driven at a low speed towards a physical.
