A fossil fuel is something-such as coal or a gas-that is now the remains of the once living organisms. Those organisms formed in the geological past. (Illinois Coal Association, 2013)
Coal is an important resource that we use in our lives. Coal is something that we use all the time. Coal produces energy when burned, which then powers what we use, want and in some cases, need. (Illinois Coal Association, 2013)
Coal is generally a dark colored rock. When burned—it produces heat. The chemical make-up of coal is Carbon, Hydrogen, Nitrogen, Oxygen, and Sulfur. It also contains very small amounts of other minerals such as Aluminum and Zirconium. Coal is combustible—which means it can catch fire and burn very easily. (Tribal Energy and Environmental Information—CLEARINGHOUSE, 2013)
There are two different ways that coal can be mined. One way to mine for Coal is underground Mining—which sometimes is also known as Deep Mining. Most are not aware that over the more recent years, we have made much significant advancements regarding the computerization and mechanization of operations. The technological advancements have made a dramatic effect on the efficiency of deep mining. When the beds of coal, or ‘coal seams’ are 200 feet or farther down under the surface, is when deep mining is considered “required”. Most of the mines in the United States are 1,000 feet or less. There are a few that go as deep as 2,000 feet. Miners are transported into these mines from the surface. By elevators. The cars that these miners are on are cars that are on railroad tracks, traveling down into the earth on a sloped entrance. (Illinois Coal Association, 2013)
Deep mining can be very troublesome at times. It is of high importance to keep the deep mines highly v...

The Making of a Hardrock Miner written by Stephen M. Voynick, describes his own personal experiences as a hardrock miner in four different underground mines in the western United States, the Climax molybdenum mine in Colorado, Hecla Lakeshore Project a copper mine in Arizona, and two uranium mines in Wyoming. Rather than a book telling of the fortunes gained and lost, this book was about the relationships gained, but then also lost through mining. Stephen M. Voynick’s direct words and simple writing style provided a book that was an easy read and educational about mine work and safety.
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.
Coal mines in these times were glorified death traps and collapsed. Often. Workers or their families were basically never compensated for anything, and even when they took things to court, essentially no court was sympathetic toward any coal miner or their family, and if their father or brother died, they were on their on for the rest of their life, often then forcing child boys to work if they weren’t already. Also, not many workers spoke proper english in the mines, so they could not read instruction signs, and by misuse of equipment, killing themselves and/or other
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)
Coal production had become a driving force behind the United States industrial revolution. Coal was used for a variety of purposes including powering steam engines, iron manufacturing, and the heat in homes and towns. One of the largest users of coal in southern Colorado was the Colorado Fuel and Iron Company (CF&I). Their furnaces were heated with coal from, he Culebra Mountain range in the southern part of Colorado was known for having some of the richest coal in the state. The coal is glossy black bituminous coal the second highest grade of coal available.
Coal is considerably one of the most important sources of energy in nature and is one the most significant sources for power generation worldwide. The excavation and importance of coal became mainstream and apparent during the Industrial Revolution of the 19th and 20th centuries.
...d deep in the earth) or poisons gas, and collapses were not uncommon. In an attempt to avoid these issues they set up ventilation and had young children called trappers open and close them so coal trucks could pass through. They also deemed it would protect the rest of the coal if an explosion were to occur. But convenient inventions were soon devised; the air pump (1807 john bundle) and the safety lamp (1815 sir Humphrey Davy).The air pump was used to move poisonous or explosive gases and the safety lamp prevented explosions too by encoding the candle in a barrier of glass and metal. Despite all the safety changes the mine still remained immensely dangerous. Coal mines were especially inhumane to children some trappers were employed as young as five and were expected to carry bundles of coal much too heavy for them which caused many deformities in the children.
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...
Roughly 68 percent of the electricity generated in the United States of America is produced by fossil fuels. That includes petroleum, natural gases and coal. Although coal contributes around 37 percent to the factor, it is by far not the cleanest of them all. Some might argue that it is good for the economy because it is cheap and it creates jobs.. But the other side of the story portrays coal mining as a process that kills thousands of coal miners a year and that it practically destroys the environment around the mining with soot and air pollution. Mining now days is a big part of urbanization; due to how cheap the process is. There are different ways that coal mining is done. Mainly mountain top removal is done but there are many other
The mine owners “worried.that the mines would have to be shut down unless water could be pumped out of the shafts.” “The engine successfully raised water from the bottom of deep mines.” (Siegel, 17) This saved the shutting down of the mines, which were essential to further the economy. Not only did the steam engine save the mines, it provided a method of mining that proved to be extremely quicker than the traditional techniques.
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.

The accidents involving machinery kill and/or hurt more coal miners in a year than any other mining accident. The machinery in mines are located in cramped spaces with little light, causing miners to have two times the chance of accidents. The accidents involving roof and rib failures can usually be averted if a mining company has a roof support plan. For a roof support plan to be made, information like entry widths, mine geometry, the number of pillars that must be left up right, and the number of bolts that must be used are needed (Cobb 3 of 5) Accumulations of gases in underground coal mines is another very serious hazard. If certain gases like methane and carbon monoxide are at or above 5% in the air they can cause violent explosions. Blasting in coal mines are the main cause for such dangerous levels of carbon monoxide.
When coal gets burned they start to release harmful dangerous toxins such as mercury, lead and arsenic that will then escape into the air. It also releases large amounts of carbon dioxide (CO2) into the atmosphere. These emissions increase the greenhouse effect in the atmosphere and lead to global warming.
There are three types of fossil fuels- coal, crude oil, and natural gas. Coal was formed very slowly. Even the “newest” coal we use today was formed a million years ago. Most of the coal we use was formed 300 million years ago, when the Earth was covered with swamps. When plants and trees died, they sank to the bottoms of the swamps. These plants and trees were layered on top of each other, forming a substance called peat. Peat is considered the first stage in coal formation. It is a mixture of water, leaves, braches, and other plant debris. Over time, the Earth changed, and deposits of sand, clay, and other minerals were formed, burying the peat. Sedimentary rock...
