Coal

Introduction Coal is a combustible black or blackish brown sedimentary rock usually occurring in rock strata in layers or veins called coal beds or seams. The harder form such as Anthracite may be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal from different stratigraphic sequence differs from each other in terms of their chemical composition and physical properties. These differences may arise due to the probable difference in the supply material

tonnes of steel making coal produced in 2013, Teck Coal Limited is the largest producer of steelmaking (coking) coal in North America and the second largest exporter of steelmaking coal with approximately 95% of the coal produced being exported to various countries in Asia, Europe and South America. China, Japan & Korea form the bulk of the countries who import steelmaking coal from Teck Coal Limited (Teck Resources Limited, 2013). Figure 1 below shows a breakdown of the world coal reserves according

its coal. Sam Weis explains in “The Local and Worldwide Impacts of Mining Alaska’s Coal,” that Alaska is home to an estimated 5.5 trillion tons of coal, which is approximately one-eighth of all the coal on Earth (25). The energy that comes from burning coal is in great need not only in the United States, but also all over the world. According to Gail West, in his article titled Alaska’s Coal Clean Burning and Abundant,” “Japan, South Korea, and Chile are three primary markets for Alaska’s coal exports

A coal power station turns the chemical energy in coal into electrical energy that can be used in homes and businesses. First the coal (1) is ground to a fine powder and blown into the boiler (2), where it is burned, converting its chemical energy into heat energy. Grinding the coal into powder increases its surface area, which helps it to burn faster and hotter, producing as much heat and as little waste as possible. As well as heat, burning coal produces ash and exhaust gases. The ash falls to

Environmental Impacts of Coal According to researchers Armstrong & Menon (1998), coal is a major energy source, constituting 25% of energy consumption worldwide (21% in the United States) and 40% of electricity generation worldwide (45% in the United States). Coal accounts for 40% of anthropogenic CO2 emissions and is therefore a major contributor to climate change (Armstrong & Menon, 1998). Coal can be produced through surface or underground mining both dangerous operations for workers. Injuries

Coal mining is not only a dangerous job, but also life threatening and deadly. Many accidents have happened over the years and coal mining is less popular than it was when it first started. Even though today fifty percent of our electricity is powered by coal. There are four different types of coalmines, each very different. The first type are drift or slope mines, they are driven into valley walls near seams of coal. The second types of mines are shaft mines, these types of mines use pumps to

The Dangers of Coal : The dangers to the miners themselves are only a portion of the problem. Environmental issues abound as well. Strip mining has caused massive environmental complications.numerous accidents throughout the years. The danger of black lung disease from long-time exposure in coal mines is also well documented.They cause environmental issues. Coal mining carries numerous risks. It is harmful to the planet. It is harmful to people involved in any aspect . it. Some of the threats are

Coal Burning Releases Huge Amounts of Air Pollution Coal is a cheap, plentiful and dirty source of fuel. The leading cause of global warming comes from burning coal. It is a sedimentary organic rock that contains over 40% carbon and is formed by ancient plants and animals. As plants die off, they pile up into peat, found it marshy damp regions, and used for fuel. Peat takes 4,000 to 100,000 years for 1 meter of peat to accumulate (Boucher). The older the coal gets, the harder and blacker it

the market sounds like an open and shut case for the mining of coal. There are always two sides to every story and the opposition to coal mining offers solid evidence why the mining of coal is not as perfect as it seems. Upon further investigation information is available stating coal mining is responsible for deforestation contributing to the destruction of habitats that support our wildlife. The techniques utilized to gain access to coal include the removal of soil, plants, and trees. This technique
