Coal production at about 5.3 mln tonnes in May

Polish coal mines produced 5.3 million metric tons of coal in May, while coal sales amounted to 5.1 million tons, state industry restructuring agency ARP reported. Coal reserves at the end of May are estimated at about 2 million tons, almost 200,000 more than a month ago. This means that the coal extracted but not sold in May increased the reserves.
