Essay On Coal Mining

Surface mining has several benefits compared to underground mining. Surface mining is done by removing the topsoil with machinery and the coal is then removed from the open coal seam. Surface mining has several benefits compared to underground mining, coal retrieval is high 85% to 90%, contrast to 40% to 70% in underground mines. Yet, it is a highly destructive form of surface mining is destructive to an entire region, the coalfield areas of West Virginia, Kentucky, Tennessee, and Virginia, for one reason only: profit. The second method is more predictable, underground mining which consist of longwall, as well as room and pillar mining.

6. Coal Gas and Coal Liquid as Transportation Fuel – Present Transportation Industry does not make much use of Coal as Fuel. However, the increasing cost of Oil has made it reasonable to consider converting Coal into Gas and Liquid, which can be used to power vehicles, ships etc. 7. Coal tar-

“To Dance with the Devil” is an informative article that informs readers of the negative consequences that have come from coal mining. The text educates readers of how coal mining is becoming detrimental to the health and safety of the residents of southern West Virginia. The text informs readers by having a strong subject, persuasive appeals, and having a clear purpose for the

Introduction Coal is a variety of solid, combustible and organic sedimentary rocks formed from vegetation that has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years (IEA, 2017). Around the world , requirements for energy and electricity are met by fossil fuels amongst which coal is the most abundant and broadly distributed. It is the most common fuel choice because it is a secure and low cost energy source and is relatively easy to mine, ship, and store. Coal is the second source of primary energy after oil and is mostly used for power generation.

As time goes by, people are racing to develop technologies in order to help solving problems, such as building the industries and all of its machines. However the industrial itself has several drawbacks such as the industrial waste. Sludge soil that contaminated by heavy metal is one of the examples of industrial waste. Heavy metals have a negative effect on human’s health, such as mental disorder. Exploration, transportation, and exploitation of crude oil can cause marine and terrestrial oil pollution.

However, when ironworking and shipbuilding caused the forests to shrink rapidly, it became a time where it was a necessary to find an alternative option. So, it began in 1709, an ironmaster named Abraham Darby I, succeeded in producing cast iron using coal. During the process of coal turning into coke, most of the sulphur became lost as sulphurous gases. These gasses allowed the coke to go through smelting processes leading to the production of iron.

If having disgusting matter in the water was not bad enough, the amount of greenhouse gas emissions are just as bad. According to a source, most of the gas emissions come from the electricity that it requires to run a slaughterhouse. “The main source of these emissions is from the electricity used to run the slaughterhouses and to get rid of the previously mentioned wastewater as well as packing, cooling and transporting the dead animals” (Farr). The reason why greenhouse gases are dangerous to the environment is because they have been connected to global warming. Two of the most common pollutants from slaughterhouses are carbon dioxide and methane.

Most welding is conducted using a foot pedal and heat adjustment is usually allowed. How to Choose the Best TIG Welders Due to the fact that TIG welding is a highly precise process that hardly creates any spatter, it makes it ideal for DIY welding, automotive welding and other applications that require thin materials. Consider the following when choosing a TIG welder: • Amperage range plays an important role in deciding on the right TIG machine. One that provides the widest range possible at the best possible cost is usually a good starting point.

One of these fuels is known as the element thorium. Thorium has great potential to be a reactor fuel because it outputs far more energy at the same cost, as well as being a safer material to use in the event of a nuclear meltdown (“Pros and Cons”). Another pro of nuclear energy is its relative safety compared to other sources of energy. Fossil fuel energy comes with a high rate of accidents and death. Mining accidents, oil rig explosions, and illnesses such as lung cancer and other ailments are far more common to occur than issues with nuclear reactors.

They are able to meet the needs of large industrialized cities as well as the suburban towns, as the energy is quick to create, meaning that they are able to make large amounts of energy if it is required due to an emergency ("Nuclear Fission Advantages and Disadvantages"). Small amounts of U-235 can produce large amounts of energy while burning of fossil fuels produces much less energy with a much larger amount ("Advantages and Disadvantages of Nuclear"). Nuclear fission has been proved to be the most powerful and efficient source than any other alternative energy sources, due to the advancement in technologies, it has made it a more viable option than others. It is due to this, why many countries are putting huge investments in nuclear power ("Nuclear Energy"). It also makes the electricity cheap as the cost of uranium, is quite low and also the average life of a nuclear reactor ranges from 40-60years, so it is great investment it can last a really long time.

Some important states for copper mining are Utah, Nevada, Arizona, Miami, Globe, Montana and New Mexico. The states with copper mining have a higher chance of having environmental issues, and negative and positive effects on the communities surrounding these mines. The negative effects are that the communities can have pollution from the mines. The positive effects are that more products can be produced from having these copper

The main Anthracite mine was located in the “Coal Region” in Northeastern Pennsylvania. While the mines became deeper, the workplace conditions were on a steady

Particulate matter is dust particles, soot, fly ash and other particles in the air they come. Particulate matter can trigger asthma because they can get stuck in the lungs therefore, triggering asthma attacks. The major sources of particulate matter are coal power plants, factories, and diesel factories. Another air pollutant that triggers asthma attacks are ground level ozone. Ground level ozone is the toxic component of smog and it makes existing asthma worse.

Hydraulic fracturing is a process that used to release the natural gas that is located underground. In this process, millions of water is pumped in addition to sand and chemicals under the ground to break the rock apart in order to facilitate natural gas release. A threat would occur as a result of using chemicals in fracturing and this could be either underground or during handling of the waste fluid which sometimes spilled on the nearby ground (ProPublica, 2015). In the Gasland documentary movie, the hydraulic fracturing danger is explored. This danger has environmental impacts such as contamination of ground water, reduction in a fresh water source, and risk to air quality, which in turn have a long-term effect on human health.

Extracting such large amounts of coal at a time can create areas of problem for the land above ground. This can damage structures or buildings. Longwall mining can increase sulfate levels in water as well as disrupt animal habitats. The cons may be harmful, but the amount of income and jobs provided by this method overrule the
