Abstract

The ring space discharge device (6) is arranged in the ring space behind a dip wall aperture (7) closable by a closure device (8, 9), so that the material from the mining extraction space entering the ring space can be discharged. In the dip wall (2) is a worm aperture (16), which is closable by a closure device (17, 18). To the worm aperture connects a conveyor device (14) for direct discharge of material from the mining extraction space, which crosses the ring space. An overflow conduit (21) connects the mining extraction space and the ring space. A mining extraction space end (22) of the overflow conduit issues in the upper area of the mining extraction space and a ring space end (23) of the overflow conduit issues in the lower area of the ring space.
