Rösche

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.

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.

[2] 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.

A recess in the stowage for the extraction of ventilation in mining is called a Wetter-Rösche.
