In the general table of coal classification, what does the numerical value represent? Category symbol Code VrPM Bituminous coal WY01, 02, 03 ≤10.0— Sub-bituminous coal YM11, 12, 13, 14, 15, 16 21, 22, 23, 24, 25, 26 31, 32, 33, 34, 35, 36 41, 42, 43, 44, 45, 46 >10.0— Lignite HM51, 53 >37.0 ≤50 Defined by the code? Why isn’t there a 04?
The forum is so indifferent; I post messages but no one reads them, no one replies, and no one comments. Even when I delete bad posts, no one seems to care about it. Disappointed; I have lost confidence in this forum.
