Description
The coal waste piles and fly ash piles that resulted from the combustion of the coal represent one of the most significant environmental impacts caused by exploitation and utilization of coal from Douro Coalfield. The organic petrography and geochemistry studies indicate the existence of similar petrographic features in samples and the occurrence of high combustion temperatures in coal waste piles. There is a significant amount of unburned material in coal waste piles and fly-ashes samples, which indicates that the combustion was not complete
