According to the latest national coal mining association's international coal review, US coal exports increased from January to June 2011 to 53.6 million short tons, an increase of 35%. The strong demand for thermal coal and metallurgical coal in Asia and Europe will drive the US’s annual export volume to reach more than 100 million tons, which is the highest level in the past 20 years. The National Mining Association's May economic forecast predicts that the US coal export volume in 2011 will reach 101.5 million tons.
