Study on oxidation trend of coal produced in Tuha Mining Area
In order to determine the oxidation trend,the changes in calorific value and volatile content of three kinds of Tuha coal with different coal qualities stored in Caofeidian Port were analyzed by experiments.The experimental results show that the volatile matter has no significant decreasing trend with the extension of storage time.The calorific value decreased significantly with the extension of storage time;and the decrease was the largest in 30 to 40 days,while there was no significant difference in the oxidation trend of each particle size.
