Abstract
The present method relates to a method of determining a route for automatically controlling a mobile mining machine. The route is determined computer-aidedly by executing, by a data processing machine configured for generating routes, the following steps of: retrieving an environment model comprising wall location data, receiving from a user at least an input for determining a starting point of the route and an input for determining an end point of the route, determining the route between the starting point and the end point on the basis of the environment model and data concerning properties of the mining machine, wherein the route is determined as route points at least for which position data are calculated, and storing the data determining the route to be used for automatically guiding the mining machine.
