A ''Rösche'' is a German mining term that refers ''inter alia'' to a gullet (''Wasserseige''), a trench for draining water in the lower part of a

mine gallery An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adit ...

. In order to keep the actual gallery entrance (''Stollenmundloch'') free and guard against backflooding the ''Röschen'' were, in many cases, extended to below the entrance or led even further away, underground, to the nearest stream or river. By contrast the term ''Rösche'' was also used to describe the channels or "leats" through which the driving water for mining equipment was led into the pit (''Aufschlagrösche'' or driving water leats) or out of the pit (''Abfallrösche'' or drainage leats). Unlike a gallery, a leat will have a gentle incline into the pit. Also referred to as a ''Rösche'' are the tunnel-like sections of mining ditch ('' Kunstgraben'') systems. These are not underground structures. In the Harz Mountains of Germany such a tunnel is also known as a ''Wasserlauf''. See Upper Harz Water Tunnels. A recess in the stowage for the extraction of ventilation in mining is called a ''Wetter-Rösche''.Walter Bischoff, Heinz Bramann, Westfälische Berggewerkschaftskasse Bochum: Das kleine Bergbaulexikon. 7th ed., Verlag Glückauf GmbH, Essen 1988,
