The World’s Friendliest Countries
They say you can never go home again–and you may not want to after relocating to Canada, Bermuda or South Africa.
These are the countries where it’s easiest to befriend locals, learn the language, fit into the new culture and integrate into the community, according to respondents to HSBC Bank International’s Expat Explorer survey, the results of which were released late last month.

Canada was most welcoming for the second year in a row; more than half of survey-takers there said they’d made friends with locals. In Bermuda 57% have had the pleasure, and the same for South Africa.

To determine the world's friendliest countries, Forbes looked at the results of HSBC Bank International's Expat Explorer survey in four categories: ability to befriend locals, success in learning the local language, capacity for integrating themselves into the community, and ease in which they fit into the new culture

One of the main advantages of becoming an expat Down Under, according to the survey, is the ease of setting up in the country.

World’s Biggest Diamond Mine is located at Mirna, Eastern Siberia, Russia. The mine is 525 meters (1,722 ft) deep and has a diameter of 1,200 m (3,900 ft).

The mine is so big and giat that the airspace above the mine is closed for helicopters because of a few incidents in which they were sucked in by the downward air flow. To give an idea how big it is here is is a fine illustration.

This giant truck, BELAZ (200-220 ton payload ) (see Figure 1), looks like small spot on next picture (see Figure 2). The truck in the picture, one of the biggest in the world, is just a small point in comparison to the diamond mine.

History:
The mine was discovered on June 13, 1955 by Soviet geologists Yuri Khabardin, Ekaterina Elagina and Viktor Avdeenko during the large Amakinsky Expedition in Yakut ASSR. They found traces of volcanic rock kimberlite which are usually associated with diamonds. This finding was the first success in the search for kimberlite in Russia, after numerous failed expeditions of the 1940s and 1950s. For this discovery, in 1957 Khabardin was given the Lenin Prize, which was one of the highest awards in the Soviet Union.

The development of the mine had started in 1957 in extremely harsh climate conditions. Seven months of winter per year froze the ground into permafrost, which was hard in winter, but turned into sludge in summer. Buildings had to be raised on piles, so that they would not sink in summer, and the main processing plant had to be built on a better ground found 20 km away from the mine. The winter temperatures were so low that car tires and steel would shatter and oil would freeze. During the winter, the workers used jet engines to defreeze and dig out the permafrost or blasted it with dynamite to get access to the underlying kimberlite. The entire mine had to be covered at night to prevent the machinery from freezing.
