Finally, changing regulations, laws, and judicial rulings can affect mining, transportation, processing, and marketing, and thus the classification of coal resources. The concept of a reserve base was developed to alleviate these difficulties ( Geological Survey, 1976, p. B2). The reserve base is identified coal defined only by physical and chemical criteria such as thicknesses of coal and .

Upon inspection of the list one would notice the absence of China, Russia and India. These countries use similar, but in most cases more elaborate classification schemes. The difference between a resource and reserve basically boils down one thing: a feasibility study. Not included in the classification, but often mentioned is a mineral occurrence.

Coal, the most carbonintensive of the fossil fuels, accounts for 70 percent of energy used in China today and is responsible for about three quarters of electricity generation.
19 April 2005 Definition of Probable Ore Reserve. ¾"A 'Probable Ore Reserve' is the economically mineable part of an Indicated, and in some circumstances, a Measured Mineral Resource. It includes diluting materials and allowances for losses which may occur when the material is mined.
Coal reserves World coal reserves in 2018 stood at 1055 billion tonnes and are heavily concentrated in just a few countries: US (24%), Russia (15%), Australia (14%) and China (13%). Most of the reserves are anthracite and bituminous (70%).

Sep 13, 2018· Classification of Coal. Coal can be classified on the basis of carbon content and time period. Types of coal on the basis of carbon content. Anthracite is the best quality of coal which carries 80 to 95 per cent carbon content. It ignites slowly with a blue flame. It has the highest calorific value. It is found in small quantity in Jammu and Kashmir.

Classification of coal based on volatile matter and cooking power of clean material. After a continuous process of burial and alteration, chemical and physical changes occur until the coal is classified as bituminous dark and hard coal. Bituminous coal ignites easily and burns long with a relatively long flame. If improperly fired bituminous coal is characterized with excess smoke and soot.
Coal is the main energy resource in China. However, currently there is an overcapacity of coal; this is problematic in relation to sustainability, emphasizing the importance of research on peak coal.
