1. A method for positioning a mobile mining vehicle, wherein scanning data is determined by scanning an environment of the mining vehicle while the mining vehicle is driven, comprising the steps of: determining location information for the mining vehicle with a positioning unit on the basis of the scanning data and pre-stored environment model data including location data of at least edges of an operating area, wherein level information is associated with at least some of the environment model data; determining a location level of the mining vehicle from the positioning unit; selecting environment model data from the positioning unit to be used on the basis of the determined location level; and retrieving, in response to a change of location level during driving, environment model data associated with a new location level for use in the determination of the location information.
