Abstract
A method for using a mining vehicle, arrangement in a mine, rock drilling rig, and mining vehicle. Tasks according to a work cycle are performed at work sites with a mining work device in a mining vehicle. At the work site, the vehicle is connected to an external electrical network. An energy storage of the vehicle is charged during the work cycle defined by a excavation plan, when the vehicle is at a work site. After the work cycle is done, electricity obtained from the energy storage is used in a transfer drive.
