@aaron_witt: German potash mine one year ago… — This was my first time a few thousand feet underground! — The potash deposit is essentially salt thought to be from an ancient ocean that dried up about 250 million years ago. — @salzkumpel mines the deposit by first drilling and blasting enormous tunnels and caverns. Loaders like these then step in to haul the material to conveyors, which transport the potash, sometimes tens of kilometers, to an elevator. — Once the potash emerges on the surface from over 3000’ beneath the earth, they process it into potassium, which is an essential fertilizer. — In other words, it’s impossible to feed the world without operations like K+S! #loader #mine #mining #heavyequipment #operator
