Nanna Heitmann Into the mountain you take nothing with you what you wear on daylight. Shoes with steel caps and puncture-proof soles. Shin guards, goggles, gloves, neckerchief, helmet. Fireproof underwear, thick
(...) socks. In the end, a wide belt to which the eight-kilo battery is hung for the miner's lamp and, just as heavy, the CO2 filter in case of emergency. Prosper Haniel Coal Mine, Bottrop, Germany. 2018. © Nanna Heitmann | Magnum Photos
