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 (7) 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 borderi ng 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 th e switch arranged in connection with the mast, thereby causing the mining vehicle to stop. |
