Mirna Diamond Mine
- Russia - No longer Operational
Natural diamond sources
have been discovered in approximately 35 different countries around the
World across several continents. Diamonds, and
consequently mines like the Mirna Diamond Mine in Russia, are found in areas where there have been volcanic
activity or erosion and where natural elements such as streams, rivers
and even glaciers might have taken them. When such sources are
discovered mines, such as the Mirna Diamond Mine, often follow. The
Mirna Diamond Mine has ceased operation since its supply of
diamonds was exhausted. While in operation the mine yielded 2 million
carats every year. The Mirna mine is now famous as the world's
largest man-made hole. For additional facts and

Information about
Diamond Deposits
Diamonds reach the surface of the earth via volcanic pipes or via placer
/ alluvial deposits. The purpose of the
mines is the extraction of valuable diamonds from the earth. The mines
are plant operations built to extract diamond crystal from either
underground or from the surface. When diamonds are extracted
underground, the mine needs a system of excavations in the rock to gain
access to the kimberlite rock. There are a limited number of
commercially viable diamond mines currently operating in the world which
use tunnelling and excavation methods. However, diamonds are also mined
using the Placer or Alluvial mining methods when host rock is washed
away by streams and rivers and diamonds are deposited as sediment in the
stream sands in 'placer deposits' which also called Alluvial deposits.
