The Mirny diamond mine in Russia is now abandoned. But for one period of time, it was the largest diamond mine in the world. Located in Siberia, the mine is more than 525 meters deep and has a diameter of 1,200m. It is one of the largest excavated holes in the world.
This documentary takes you on a journey through the diamond mine. It is now operational, but it lost the title of largest diamond mine in the world.
With that in mind, mining in the mine began in 1957 in extremely harsh climate conditions. The Siberian winter lasts seven months and freezes the ground. This makes it harder to mine.
Take a look at the mining experience in Mirny, Siberia.
