Have you ever been 400 meters underground? It's like the Empire State Building was flipped top side down and hammered into the ground as if it was a giant nail. Then, where its tip arrives is around 420 meters, so exactly there these miners work and exactly there the guy Ilya went down to take some
photos. The mine is not a coal mine - it's a potassium mine - they get this mineral which is used as fertilizer, and the company, Uralkalij - is the world's largest producer of potassium. Thanks to Ilya we can see where most of the world's potassium fertilizer is coming from.
