Demonstrated Coal Reserves, by Type of Coal, and Method of Mining, by State statistics

[In millions of short tons (495,666 represents 495,666,000,000). As of January 1. The demonstrated reserve base is the sum of coal in both measured and indicated resource categories of reliability. Measured resources of coal are estimates that have a high degree of geologic assurance from sample analyes and measurements from closely spaced and geological well known sample sites. Indicated resources are estimates based partly from sample and analyses and measurements and partly from reasonable geologic projections. For more information on the classification of coal resources and related terminology, see report cited below]

* Definitions

Coal: A black or brownish- black solid, combustible substance formed by the partial decomposition of vegetable matter without ac- cess to air. The rank of coal, which includes anthracite, bituminous coal, subbituminous coal, and lignite, is based on fixed carbon, vola- tile matter, and heating value. Coal rank indicates the progressive alteration, or coalification, from lignite to anthracite. Lignite contains approximately 9 to 17 million Btu per ton. The heat contents of sub- bituminous and bituminous coal range from 16 to 24 million Btu per ton, and from 19 to 30 million Btu per ton, respectively. Anthracite contains approximately 22 to 28 million Btu per ton.

Coal Coke: A hard, porous product made from baking bituminous coal in ovens at temperatures as high as 2,000 F. It is used both as a fuel and as a reducing agent in smelting iron ore in a blast furnace. used to classify an establishment as commercial are 50 through 87, 89, Anthracite: A hard, black, lustrous coal containing a high percentage of fixed carbon and a low percentage of volatile matter. Often referred to as hard coal. It conforms to ASTM Specification D388- 84 for an- thracite, meta- anthracite, and semianthracite.

Bituminous Coal: A dense black coal, often with well- defined bands of bright and dull material, with a moisture content usually less than 20 percent. Often referred to as soft coal. It is the most common coal and is used primarily for generating electricity, making coke, and space heating. It conforms to ASTM Specification D388- 84 for bituminous coal. In this report, bituminous coal includes subbituminous coal.

Lignite: A brownish- black coal of low rank with a high content of moisture and volatile matter. Often referred to as brown coal. It is used almost exclusively for electric power generation. It conforms to ASTM Specification D388- 84 for lignite.

Demonstrated Reserve Base (coal): A collective term for the sum of coal in both measured and indicated resource categories of reliability, representing 100 percent of the in- place coal in those categories as of a certain date. Includes beds of bituminous coal and anthracite 28 or more inches thick and beds of subbituminous coal 60 or more inches thick that can occur at depths of up to 1,000 feet. Includes beds of lig- nite 60 or more inches thick that can be surface mined. Includes also thinner and/ or deeper beds that currently are being mined or for which there is evidence that they could be mined commercially at a given time. Represents that portion of the identified coal resource from which reserves are calculated. *
