Circular 891 - Coal Resource Classification System

COAL RESOURCE CLASSIFICATION SYSTEM The classification system presented herein is an expansion of the system adopted in 1976. It employs a concept by which coal is classified into resource/reserve base/reserve categories on the basis of the geologic assurance of the existence of those categories and on the economic feasibility of their recovery.

13.09.2018  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.

What is a coal reserve? – Jean-Marc Jancovici

Ultimate reserves designates all the coal that can eventually be mined in a given zone (that can be the whole planet). It is therefore the cumulated extraction of coal, from beginning to end, in a given zone, if the only limit is technico-economic in an “open economy” (no wars, no strong regulation or ban, etc).

The coal resource and reserve classification system currently in use in the United States has undergone more than a century of development. The current system was adopted in 1976 by the U.S. Geological Survey and the U.S. Bureau of Mines (USDOI, 1976) and modified in USGS Circular 891 (Wood et al., 1983). Circular 891 established a uniform foundation for coal resource and reserve assessments by providing standard definitions, criteria, guidelines, and methods. Circular 891 defined coal ...
