Coal is a non-living resource and a non-renewable resource; it can be defined as a resource that is being consumed at a faster rate than it can be replaced. Coal is formed from the compression of vegetable matter over millions of years. Coal is used to power electricity and a range of everyday products that will be discussed throughout the report and is mined underground or in an open pit.
Questions needed to be asked to determine how long the resource will last.
• How much of the resource remains?
• How quickly is the resource being consumed? Different resources are being utilized at different quantities and rates.
• Is the resource renewable or non-renewable? Time taken to be naturally replaced.
• Would it be expensive to recover the resource? Recovery can mean its extraction from raw materials and wether a resource is recovered or recycled can deepened on the market value of itself.
Extraction
Coal is mined using giant machines to remove the coal from the ground. Only black coal is mined underground, as it is more valuable other coal is mined in an open pit.
The process usually involves creating a geological map of the area, then carrying out geochemical and geophysical surveys, followed by exploration drilling. This allows an accurate picture of the area to be developed. The area will only ever become a mine if it is large enough and of sufficient quality that the coal can be economically recovered.
The youngest coal is not even coal yet it’s called peat. It is cut from the earth, dried and burned for heat. The energy content of peat is quite low.
Young coal is called lignite, and is soft and brown, not much different than dried peat. Lignite has low energy content. The carbon content is low also; Lignite is typically...

A machine known as a dragline then digs into the rock to reveal the coal, the machines hollow out the tiers of coal and dump millions of overburden, the previous mountaintops, into constricted nearby valleys, thereby producing valley fills. Coal companies have covered over 1,200 miles of biologically crucial Appalachian headwaters streams.
Objectives • To evaluate the difficulty of mining and reclamation To calculate costs, expenses, income, and profit from a hands-on mining exercise. • To evaluate the effectiveness of reclamation and its added costs to mining. To describe the increasing rarity of some non-renewable mineral resources. Introduction Minerals play an important role in our day-to-day life, but we often do not contemplate how the minerals are obtained. Minerals are scattered all over the world, just like any other resource.
Coal is by far the most abundant of fossil fuels, and will be available for much longer than oil. Having been harvested and burned since the 13th century, a massive infrastructure has been formed to quickly and efficiently mine, deliver, and burn coal. Coal is also the cheapest of fossil fuels (The Futurist, 1997)
Although coal mining is important to local and global economies, there are many environmental impacts of both the mining and use of coal that must be considered. Actions can be taken to mitigate these environmental impacts but it is up to scientists to identify these potential problems and put plans into action before it is too late.
Coal is one of the world’s most abundant fossil fuels. Coal was formed during the Carboniferous Period when dead plant material was buried and subjected to high pressure and heat. Coal is classified by moisture content and composition. There are four d...
Coal was the cutting edge of energy generation before any other source was extensively used. Wood, wind, water, and muscle power provided nearly all of the energy before the widespread adoption of coal. The greater energy density of coal provides a greater efficiency than these other methods of generating power; combine that greater efficiency with its ease of transportation and coal easily becomes the fuel of a nation. In its early days, coal was mined and consumed in England, a country short on wood and usable water power. This shortage in other areas left a gap that the relatively cheap coal could fill. Coal allowed for industry and manufacturing to grow and produce profits greater than almost any other industry. Coal gained its popularity mainly because it had an economic value in that it provided energy in quantities and in locations that were unobtainable and unreachable for the other energy sources at the time. This start in England led to momentum in ta...
Railroads can be referred to as the first big business, and the first industry to develop management bureaucracy (Ogburn 39). Railroads were a vital part of early American history during the 1800s-1860. The development of Railroads was one of the most important phenomena of the Industrial Revolution. Railroads brought social, economic, and political change to the country (Stover 26). In the United States a turnpike era and then a canal era had immediately preceded the coming of the railroads, which proved to be fast, direct, and reliable in all weather. After 1830 the railroads grew so quickly that within a decade their mileage surpassed that of the canals (Hollingsworth 28).
Railroads have made better the lives of most citizens in the US. By the 1890s, the United States was becoming an urban nation , railroads were a great way of transport between towns. They were used for the shipping of food, building materials and fuel. The presence of them could bring a territory a lot of opportunities as well as it could change its economy in many ways. Railroads also helped to shape physically the growth of towns and also a lot business grew around focal points in the railroad industry. Later on, the United States transport system was composed by 320,000 kilometers of railroads that prolonged from the Pacific to the Atlantic and vice versa and also connecting with the frontier countries, Mexico and Canada.
Lower quality coal is used for generating electricity. To generate electricity they burn the coal in a power plant to produce steam. The steam then travels through a turbine and generates power. The higher quality coal is used for making iron and steel. Coal is retrieved from nature by mining, either from an underground mine or from an aboveground mine. Due to the difficulty of underground mining coal from underground mines sells for more money. After the coal is mined it is processed to remove impurities from it. Lastly it is transported, “The cost of shipping coal can be more than the cost of mining it.” (US Energy Information Administration, 2013). Transportation methods include, truck, barge, train, and pipeline.
What comes to mind when you think of coal mining? If you're like me, coal mining means living in darkness and a cold hearted industry. Other words that come to mind are poverty and oppression. Coal mining is not a job that you dream about or get a degree for. People who are coal miners do not chose a life full of danger and repression, they get stuck with it. There are many dangers that come along with coal mining, not only for the workers, but for the environment. Coal mining and the coal industry have caused irreversible damage to our environment and has killed innocent miners.
I’ve long been familiar with the concept of coal mines, but a common occurrence I was unfamiliar with previous to this class was the concept of coal mine fires, but it is a huge problem, both economically and environmentally.
Even if materials are eventually returned to earth, fuel costs are
Coal mining can benefit humans as well as it supports the economy in many ways. Coal mining provides a lot of jobs for local communities. It provides over 7 million jobs worldwide.
In our days, mining for resources is inevitable. The resources we need are valuable in everyday life. Such resources mined up are coal, copper, gold, silver, and sand. However, mining poses environmental risks that can degrade the quality of soil and water, which can end up effecting us humans if not taken care of and many of the damages are irreversible once they have occurred.
Fuels like coal, and oil that once were a fine innovation in creating energy are now rapidly deleting and one day will be gone forever; energy that won’t last is often referred to as non-renewable energy. Besides being set up to fail and become inefficient in the future, fossil fuel energy is not clean to use and poses several environmental complications. Coal, for instance is “the dirtiest of all fossil fuels. Coal combustion not only produces sulfur oxides and nitrogen oxides that contribute to acid rain and snow, it generates millions of tons of particulates that cause asthma and other respiratory diseases.” As with all usage of fossil fuels, it creates enormous amounts of carbon dioxide, which contributes to greenhouse gas. Not only are fossil fuels dirty, they also pose as a security risk and unforgiving on the American wallet. (Saini)
