In Wujek, a coal mine in the Polish city of Katowice, the concepts of time and space get blurred.
Photographer Daniel Tchetchik accompanied the workers down the shaft and into the heart of the mine. In 1981 military and police forces entered the mine to stop a workers' strike; nine of the miners were killed. Still, despite its history, one worker says he "wouldn't trade this job for anything. Actually, maybe to be a tour guide of the place."
