Abstract
In a haulage device for the continuous removal of material excavated below ground, which can be continuously slaved between a mining machine (8) and a continuous road haulage means (2) over a defined path and narrow curve radii of the mining machine (8) while continuously hauling without interruption, the haulage device is configured as a closed-belt conveyor (9) which is movable on a suspended rail system (3), whose receiving end adjacent the mining machine (8) is coupled with a movable transfer conveyor (7) and whose end facing away from the mining machine (8) and adjacent the continuous road haulage means (2) is connected with a clamping device exerting a defined tensile stress over a defined displacement path of the transfer end of the closed-belt conveyor (8) in a displaceable transfer position onto the continuous road haulage means (2).
