World's largest diamond mine

This diamond mine in eastern Siberia - Mirny is the largest diamond mine in the world. It is so deep that the surrounding air zone is closed for helicopters after few accidents when they were sucked in by downward air flow.

Look for the tiny red arrow in the following photograph; it's pointing to a 220-ton rock-hauling truck more than 20' tall.
