The invention relates to a method of arranging data transfer between a moving mine vehicle and a control point. At least two wireless connections are established for the mine device, the connections being arranged via different base stations. Substantially the same data are transmitted using at least the two connections. The data that have already been received via another connection are rejected.

Arranging data transfer for mobile mine device

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.

Arrangement for monitoring the location of a mining vehicle in a mine

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

Monitoring location of mining vehicle using base stations in at least two sections of mine

A method for loading a dumper with broken rock or the like and an apparatus for implementing the method. In the method, a loading area is defined for the dumper. The dumper is stopped at the loading area at a predefined position for loading. An emptying area is correspondingly defined in advance for a loader for transporting the material in its bucket onto the dumper box. The apparatus includes a controller for controlling the dumper at least during loading, and the controller includes means for stopping the dumper for loading at the predefined position so that the material transported by the loader can be emptied onto the dumper box in a predefined location in the longitudinal direction.

Method and apparatus for automatic loading of dumper

A method and a system for monitoring the location of a mining vehicle in a mine. The mine comprises 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 means of a dead reckoning. The location data, based on the dead reckoning, can be updated by means of the identifier. The location data are transmitted to a mine control system for monitoring the mining vehicle.

The invention relates to a method and arrangement for preventing the passage of preferably an unmanned mining vehicle. The invention is based on the idea of providing a mining vehicle, such as a loading vehicle, with a mast ( ) arranged on its upper outer structure and extending above other portions of the vehicle. In connection with the mast there is provided an emergency stop switch. Furthermore, at the upper portion of a mine gallery, or a similar operating site, is provided a barrier boom reachable to the mast for bordering the accepted travel area of the mining vehicle. If the mining vehicle tries to leave the accepted area, the mast hits the barrier boom and thus triggers the switch arranged in connection with the mast, thereby causing the mining vehicle to stop.
