Mirny鑽石礦,西伯利亞

i’m pretty sure most people have seen this one. it’s an absolute beast and holds the title of largest open diamond mine in the world. at 525 metres deep with a top diameter of 1200 metres there’s even a no-fly zone above the hole due to a few helicopters being sucked in.

相信很多人都看過這個了.這個超大的洞擁有世上最大開放性鑽石礦的名譽.它的深度是525公尺,最上面的直徑為1200公尺. 它的上方還被設為禁航區,因為曾經有幾次有直昇機被吸入洞裡.

apparently the largest ever hand-dug excavation in the world, this 1097 meter deep mine yielded over 3 tonnes of diamonds before being closed in 1914.

世上最大手工開鑿的洞穴. 在1914年關閉以前,這個1097公尺深的礦總共生產超過3噸的鑽石
