3 Coal terminology

3.1 Coal and its product terms 3.1.1 coal coal coal Carbon-rich solid combustible organic sedimentary rock mainly transformed from plant remains through coalification, containing a certain amount of minerals, corresponding to The ash yield is less than or equal to 50% (dry basis mass fraction). Note 1.Usually in the process of geological coalification, when the total water content drops to 75% (mass fraction), the peat is converted into coal; while in the normal coalification process, there is no interference The upper limit of the conversion of coal seam to half graphite is that the average random reflectance Rran of vitrinite is 6.0%, or, the average maximum reflectivity Rmax of vitrinite is 8.0% is better for its upper limit. For climacteric contact metamorphic coal seams, the upper limit of Rmax can exceed 10%. See ISO 11760 for the above notes. Note 2.At present, the upper limit of coal ash content used in the calculation of coal reserves in China is 40%. [Source. GB/T 5751-2009,3] 3.1.2 coal equivalent coalequivalent standard coal A unified unit of measure for energy. Any energy that can generate a low calorific value of 29.27MJ can be converted into a 1kg coal equivalent value. 3.1.3 ROMcoal runofmine; ROMcoal Coal produced directly from coal mines without any screening, crushing and sorting. [Source. GB/T 7186-2008, 3.1.2] 3.1.4 raw coal Coal that may only be screened or crushed. [Source. GB/T 7186-2008, 3.1.3] 3.1.5 commercial coal Raw coal is processed coal products for sale. Note. It can be divided into power coal, metallurgical coal, chemical raw coal and other categories.
