The world's second largest hole

The second largest man-made hole in the world (surpassed only by the Bingham Copper Mine in Utah) is a diamond mine located on the outskirts of Mirny, a small town in eastern Siberia. Begun in 1955, the pit is now 525 meters deep and 1.25 kilometers across. The massive 20-foot tall rock-hauling trucks that service the mine travel along a road that spirals down from the lip of the hole to its basin. Round-trip travel time: two hours. Airspace above the mine is off-limits to helicopters, after "a few accidents when they were 'sucked in' by downward air flow..."
Open pit mining has ceased in the MIR pit and mining is continuing by underground methods.

According to the BBC, "The town is strictly off limits to outsiders without a special permit and the authorities regard any foreigners with considerable suspicion."

I'm pretty sure most people have seen this one. It's an absolute beast and holds the title of largest open diamond mines in the world. At 525 meters deep, with a top diameter of 1200 meters , there's even a no-fly zone above the hole due to a few helicopters having been sucked in. ________________ <a href="http://www.netpointar.com.ar/S_Seguridad/Netpoint_Security/default.asp">tarjetas plasticas</a>
