Heaping coals

The assumption of continuity of coalbed is supported only by geologic evidence. Coal production plus imports of coal, coke, and briquets minus exports of coal, coke, and briquets plus or minus stock changes. It is formed from plant remains that have been compacted, hardened, chemically altered, and metamorphosed by heat and pressure over geologic time. Exploration that confirms their existence and better defines their quantity and quality would permit their reclassification as identified resources. Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. The sum of "Production" and "Imports" less "Exports" may not equal "Consumption" due to changes in stocks, losses, unaccounted-for coal, and special arrangements such as the United States shipments of anthracite to United States Armed Forces in Europe. Includes beds of lignite 60 or more inches thick that can be surface mined. Undiscovered coal resources in beds that may reasonably be expected to exist in known mining districts under known geologic conditions.

Heaping coals


A naturally occurring process caused by the oxidation of coal. Includes beds of lignite 60 or more inches thick that can be surface mined. Heat buildup in stored coal can degrade the quality of coal, cause it to smolder, and lead to a fire. Unspecified bodies of coal surmised to exist on the basis of broad geologic knowledge and theory. A collective term for the sum of coal in both measured and indicated resource categories of reliability, representing percent of the in-place coal in those categories as of a certain date. Factors involved in spontaneous combustion include the size of the coal the smaller sizes are more susceptible , the moisture content, and the sulfur content. Measurements of coal thickness are more than 6 miles apart. Represents that portion of the identified coal resource from which reserves are calculated. Undiscovered coal in beds that may occur either in known types of deposits in a favorable geologic setting where no discoveries have been made, or in deposits that remain to be recognized. Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. It is most common in low-rank coals and is a potential problem in storing and transporting coal for extended periods. Undiscovered coal resources in beds that may reasonably be expected to exist in known mining districts under known geologic conditions. The speculative and hypothetical resource categories comprise undiscovered resources. Quantities of unextracted coal that comprise the demonstrated base for future production, including both proved and probable reserves. It is formed from plant remains that have been compacted, hardened, chemically altered, and metamorphosed by heat and pressure over geologic time. Coal production plus imports of coal, coke, and briquets minus exports of coal, coke, and briquets plus or minus stock changes. In general, hypothetical resources are in broad areas of coalfields where points of observation are absent and evidence is from distant outcrops, drill holes, or wells. The rank of coal, which includes anthracite, bituminous coal, subbituminous coal, and lignite, is based on fixed carbon, volatile matter, and heating value. Includes beds of bituminuous coal and anthracite 28 or more inches thick and beds of subbituminuous coal 60 or more inches thick that can occur at depths of up to 1, feet. Coal rank indicates the progressive alteration, or coalification, from lignite to anthracite. The sum of "Production" and "Imports" less "Exports" may not equal "Consumption" due to changes in stocks, losses, unaccounted-for coal, and special arrangements such as the United States shipments of anthracite to United States Armed Forces in Europe. Anthracite contains approximately 22 to 28 million BTU per ton. A solid carbonaceous residue derived from low-ash, low-sulfur bituminous coal from which the volatile constituents are driven off by baking in an oven at temperatures as high as 2, degrees Fahrenheit so that the fixed carbon and residual ash are fused together. The assumption of continuity of coalbed is supported only by geologic evidence. Coke from coal is grey, hard, and porous and has a heating value of
