approaches to estimating CH4 emissions from coal mining. The first approach, outlined in the Tier 1 and Tier 2 methodology is based on coal production and an emission factor. The second approach, the Tier 3 method, uses minespecific measurement data from ventilation and degasifiion systems to develop national estimates for underground mines

The other (nonspecific) emission factors were developed at a variety of mine types and thus are applicable to any western surface coal mine. As an alternative to the single valued emission factors given in Table 11.94 for train or truck
The estimation of greenhouse gas emissions from South
The mines sampled represented 53 per cent of all surface coal mining activity. Accordingly the estimated total emissions were scaled up, to arrive at estimates of 1 950 000 ± 350 000 t/a CO2, 2040 ± 580 t/a SO x, 306 ± 85t/a NO, and 31 ± 9 t/a NH3 for all surface mines. Methane was detected only from burning coal, and due to the difficulty in
Summary The National Academies Press
The coal industry in the United States—encompassing coal mining, processing, and transportation—is a relatively small but vitally important component of the nation''s economy.Coal provides nearly a quarter of all energy supplies in the United States, with most of this coal used to generate more than half of the nation''s electricity.

The court also required that the federal coal be stockpiled and stored at the mine and that it not be sold or shipped. In its August decision, the court had found that the Office of Surface Mining failed to comply with NEPA, including by failing to take a hard look at foreseeable greenhouse gas emissions and at the impacts of coal transportation.
Carbon Dioxide Emission Factors for Coal
Carbon Dioxide Emission Factors by Coal Rank and State of Origin. The (arithmetic) average emission factors obtained from the individual samples (assuming complete combustion) (Table FE4) (10) confirm the longrecognized finding that anthracite emits the largest amount of carbon dioxide per million Btu, followed by lignite, subbituminous coal, and bituminous coal.
Coal and the environment U.S. Energy Information

Assessing Emissions from Active and Abandoned Coal Mines
The gas emission zone liberates and accumulates significant amounts of coal mine methane as a byproduct of active mining. In most active mines, coal mine methane is controlled by wellbores, called gob gas ventholes. Despite the presence of these wellbores, it is not possible to capture all of the methane generated within the gas emission zone.

Assessing precision and accuracy of atmospheric emission
Assuming that stateoftheart air quality models are accurate, then the precision and accuracy of their results directly depend on the precision and accuracy of their geographical, meteorological and emission input data. There are important appliions, such as open pit mining, in which emission data are the main source of uncertainty.
