The worlds biggest hole is located in Russia.

The giant hole is actually a diamond mine in Eastern Siberia near the town Mirna.It is 525 m deep, and 1,25 km.in the diameter.

This dumper is one of the biggest in the world:length: 13,36 m width: 7,78 m height: 6,65 m

This giant machine appears just a small point in the next image.

Az árok fölötti légtérbe tilos berepülni, mivel korábban történtek itt helikopteres balesetek, mert a szívóerő egyszerűen beszippantotta a

helikoptereket.The suction above the hole resulted in several helicopter crashes, so all flight

above the hole now is prohibited.
