Coal that has a high degree of coalification with a gross calorific value above 23,865 KJ/kg (5,700 kcal/kg) on an ash-free but moist basis, and a mean random reflectance of vitrinite of at least 0.6. Slurries, middlings and other low-grade coal products, which cannot be classified according to the type of coal from which they are obtained, are included under hard coal. There are two sub-categories of hard coal: (i) coking coal and (ii) other bituminous coal and anthracite (also known as steam coal). Coking coal is a hard coal with a quality that allows the production of coke suitable to support a blast furnace charge. Steam coal is coal used for steam raising and space heating purposes and includes all anthracite coals and bituminous coals not classified as coking coal.|
In general, data on stocks refer to changes in stocks at producers, importers and/or industrial consumers at the beginning and end of each year. In some cases, however, stock series have been derived on the basis of the difference between gross availabilities for transformation or consumption and official or published data on actual consumption. A positive stock change (+) reflects additions to stocks which in effect decreases 'apparent consumption'; while a negative stock change (-) creates exactly the opposite result.
