A patcher is an entry-level laborer or assistant assigned to a driver or a senior miner. They handle the physical grunt work, such as coupling mine cars, clearing tracks, and fetching tools, allowing the primary operator to focus on running the machinery or extracting ore. The role serves as an apprenticeship where newcomers learn the layout and rhythm of the mine.
