Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverable.This is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining industry create unique ...
The heart of a coal-fired power plant is a boiler, in which coal is burned by combustion to turn water into steam. The following equation shows what burning coal looks like chemically: C + O 2--> CO 2.Coal isn't made of pure carbon, but of carbon bound to many other elements.
Dec 18, 2013· In fiscal year 2012, about 42 percent of the 1.05 billion tons of coal produced in the United States came from coal tracts leased under the federal coal leasing program. Interior's BLM is responsible for managing this program, including estimating the fair market value of the coal to be leased. GAO was asked to examine this program.
It accounts for about 50% of the coal produced in the United States. Bituminous coal is formed when a sub bituminous coal is subjected to increased levels of organic metamorphism. It has a carbon content of between 77 and 87% on a dry ash-free basis and a heating value that is much higher than lignite or sub bituminous coal.
1 EIA, an independent arm of the Department of Energy, is the primary public source of energy statistics and forecasts for the United States. The estimated amount of new generating capacity is taken from the Excel output spreadsheet for the Annual Energy Outlook 2008 report.

How coal is mined. In 2016, the United States burned roughly 728 million tons of coal, enough to fill a typical railroad car every 4 seconds .The electricity sector accounted for over 90 percent of all coal used in the United States, with the rest burned in industrial and commercial settings.
About 55% of total U.S. coal production was mined in the Western coal region. Wyoming, the largest coal-producing state in the United States, produced 40% of total U.S. coal production and 73% of the coal mined in the Western coal region. Six of the top ten U.S. coal-producing mines were in Wyoming, and all of those mines are surface mines.
Coal is a fossil fuel composed primarily of carbons and hydrocarbons. Its ingredients help make plastics, tar and fertilizers.A coal derivative, a solidified carbon called coke, melts iron ore and reduces it to create steel.But most coal -- 92 percent of the U.S. supply -- goes into power production [source: Energy Information Administration]. ...
Coal needs to be stored at various stages of the preparation process, and conveyed around the CPP facilities. Coal handling is part of the larger field of bulk material handling, and is a complex and vital part of the CPP.. Stockpiles provide surge capacity to various parts of the CPP. ROM coal is delivered with large variations in production rate of tonnes per hour (tph).
Coal washing is a process that is undertaken in a coal washery or coal preparation plant (CPP) where coal is refined or cleaned of impurities. Coal washing involves using water, mechanical techniques and relies on gravity and the difference of density between coal and it's impurities which are usually more densely packed due to the fact that ...
