The pitmen. These are the miners' dog tags.

Going deep with Michael Holtkamp

Under the roof of the Gray Coe there are countless microphones, with each microphone being suspended from the ceiling just like a clothes hook. At the beginning of a shift, each miner lowers his microphone, like the announcer in a boxing ring did in the past. When the bell rings three times, the crew goes down into the mine. Glückauf!
