CHAPTER 4 FUGITIVE EMISSIONS - IGES

The geological processes of coal formation also produce methane (CH4), and carbon dioxide (CO2) may also be present in some coal seams. These are known collectively as seam gas, and remain trapped in the coal seam until the coal is exposed and broken during mining. CH4 is the major greenhouse gas emitted from coal mining and handling.

2.7 CH4 Coal Mining Handling IPCC. CH4 Emissions: Coal Mining and Handling 131 Methane emissions also occur during post-mining handling, processing, and transportation. Some CH4 is released from coal waste piles and abandoned mines. Emissions from these sources are believed to be low because much of the CH4 would likely be emitted within the mine.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The amount of methane (CH4) released during coal mining depends on a number of factors, the most important of which are coal rank, coal seam depth, and method of mining. Underground coal mining releases more methane than surface or open-pit mining because of the higher gas content of deeper seams.

Coal mining - Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit ...

Methane (CH 4) and carbon dioxide (CO 2) are the principal greenhouse gases (Denman et al., 2007). Coal mining is a major source of CH 4 (Denman et al., 2007), which is 21 times more warning potent than CO 2 . In Brazil, fugitive emissions from coal mining and beneficiation were estimated in two inventories (MCT, 2006; MCT, 2010).

SURFACE MINING METHODS - WordPress

2-3 2.2 Strip Mining Strip mining is ideally applied where the surface of the ground and the ore body itself are relatively horizontal and not too deep under the surface, and a wide area is available to be mined in a series of strips. Typical examples of this type of mining are the larger tonnage coal mining operations in Mpumulanga.
