Discard

In the mining language, shedding is the complete abandonment of a shaft , tunnel or pit construction while the rest of the mine continues to exist.

In the Ruhr mining of the 18th and 19th centuries In the early 20th century, it was common practice to “throw it off”: Many mines dug a so-called light hole in their increasingly longer tunnels in order to improve ventilation and, if necessary, to have shorter access and transport routes. Over time the mining progressed and after a certain time a new shaft was sunk. The old shaft was no longer needed and was "thrown off", which means mostly backfilled with an offset . The United General & Erbstollen colliery is a prime example of such an approach .

"Discarded" mine workings are usually cordoned off from the rest of the mine and called " old man " in the miner's language .
