Over the 70 years that Korkinsky coal mine has been operating, it has produced over 250 million tons of coal and about 1.5 billion tons of waste rock. As a result, the open-cut mine has become the largest one in Eurasia and second largest globally - the mine's depth is over 500 meters and its diameter is about 3.5 kilometres.
