A mining camp was a temporary settlement built around a mine.
In the mirror universe, Bajor's Dahkur Hills had several mining camps, unlike the prime universe, in which it was farmland.
In 2374, Bareil Antos regaled Kira Nerys with a tale of meeting Lisea, a young woman who he met that had recently arrived in Ilvia from the mining camps. (DS9: "Resurrection")
