Anyone self respecting geek who has been spellbound by the inspired rescue of the Chilean miners, will have found plenty of great info-graphics showing just how impressive a mine is. Here we have gathered some other cutaways, sections and 3d models showing a variety of mines, from the two coal mine alternatives (room and pillar or longwall) to the cavernous chambers of salt mines. Most impressive of all, however, is the physical model of Kidd Creek mine in Ontario where the relatively insignificant looking blobs at the bottom are the world's tallest man made structures, to scale.
