AP-42 11.9 Western Surface Coal Mining
measured emission factor data base for western surface coal mines. The objective of this work assignment was to incorporate the results of those studies in the AP-42 Section 11.9 on western surface coal mining. The remainder of this report is structured as follows: Section 2 describes the revisions
AP 42 11.9 Western Surface Coal Mining
emissions estimate is needed are very similar to those of the mine for which the emission factor was developed. 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 11.9-4 for train or truck

et al. 1992). Both of these studies have since been updated by the authors and the emission factor assumptions have changed. Based on the current emissions inventory, approximately half, or 13, of the states with surface mining activities account for ~90 percent of the methane emitted to the atmosphere as a result of surface coal mining activities.

models and emission factors and make revisions as may be necessary to eliminate any significant overprediction.”The purposes of this study are to:. Improve available emission factors for surface coal mines. Develop a comprehensive data base of source activity levels, on-site meteorological conditions, and air quality data..
Greenhouse Gas Emissions From Coal Mining …
Generally, surface mining is practiced when a coal seam is within 70 m from the earths surface, whereas coal bed beyond 70 m from the earths surface is mined by adopting underground mining methods. Surface mining also known as strip mining, is the most common type of mining of coal in the world responsible for ∼8% of coal production in China, 80% in Australia, and 67% in the United States ...
Coalbed methane emissions and drainage methods …
Coal, a solid combustible mineral resource, plays a significant role in the global economy, particularly in developing countries. For coal exploitation, underground mining is widely applied, during which a large amount of disasters are likely to occur and cause great losses compared with surface mining.
Coal Mining - an overview | ScienceDirect Topics
Emissions factors for underground mining range from 10 to 25 m 3 emitted per ton of coal mined, compared to 0.3 to 2 m 3 per ton of coal that is surface mined. Table 3.1 contains methane emissions factors for underground mining for selected countries (EPA, 2006).
IMPROVED EMISSION FACTORS FOR FUGITIVE …
The primary purpose of this study was to develop emission factors for significant surface coal mining operations that are applicable at Western surface coal mines and are based on state-of-the-art sampling and data analysis procedures. Primary objectives were (1) to develop emission factors for individual mining operations, in the form of equations with several correction factors to account ...

The health and environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products.In addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas desulfurization sludge, that ...
Environmental impact of mining - Wikipedia
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
