Abstract: A method, system and access station for passage control of mine vehicles. Mine vehicles are transferred between an operation area and a manual area through one or more access stations between which there is an intermediate space, to which the mine vehicle to be transferred can be driven. When the mine vehicle is in the intermediate space, at least one access gate is closed.

Abstract: An arrangement for data transmission in a mine, and a cable reel. Data transmission between an information system of the mine and an information system of a mining vehicle is arranged using two data transmission cables. The data transmission cables are arranged in a supply cable that can be stored on a reel in the mining vehicle. The reel has a rotatable drum on which the supply cable can be wound. A first end of the drum has a first rotating connection element for connecting the first data transmission cable to the information system of the mining vehicle. A second end of the drum has a second rotating connection element for connecting the second data transmission cable to the information system of the mining vehicle.
