摘要
利用平顶山煤业集团十二矿煤质较为稳定、各层煤的黏结指数和Y值变化较小的特点,采用通过原煤的干燥无灰基挥发分推算出其浮煤的干燥无灰基挥发分,并由此确定该矿煤炭的类别。
Use of the Pingdingshan Coal Group No. 12 Mine stability, all floors of coal＇s bond index and the value of Y changes in the characteristics of the smaller, through the dry ash-free coal-volatile estimated its floating dry ash-free coal-volatile, and thus determine the type of coal.
