Coal (fuel source)

Scientists find coal underground by using a variety of methods such as drilling core samples, seismic imaging, and ground-penetrating radar to locate coal deposits. Once a potential coal deposit is identified, further exploration and sampling are conducted to determine the quality and quantity of the coal present.

Coal mines can range in depth from a few hundred feet to over a mile deep, depending on the location and mining method used. Underground coal mines are typically deeper than surface mines due to the nature of the coal deposits.

No, seams refer to layers of coal that have formed over time within the Earth's crust. These seams can vary in thickness and are important for mining operations.

The average mine temperature varies considerably from pit to pit; temperature is dependent on depth of workings and how effective ventilation is. Temperatures at the coal face can be between 13 degrees C and 30 degrees C.

Burning coal releases carbon dioxide, which (according to the US EPA) is a polluting greenhouse gas. The extra CO2 added to the atmosphere is overwhelming the carbon cycle and is causing global warming.

Yes, coal deposits have been found in Antarctica, but extracting and using them is currently not economically viable due to the extreme conditions in the region. As for oil, there have been limited exploration efforts in Antarctica, but the environmental sensitivity and protection regulations in place make commercial oil extraction unlikely.

Coal mining is often viewed as bad because it is dangerous and robs the earth of a natural resource. Long before government safety regulations, coal miners were frequently killed from explosions (caused from the slightest spark meeting natural gas), cave-ins, lung cancer from continuous exposure to coal dust, and other freak accidents.

Coal is formed from the remains of plants that lived in swamps and marshes millions of years ago. The plant material gets buried and compressed over time, eventually turning into peat, then lignite, and finally coal through a process called coalification.

Fossil fuels are still used today because they are abundant, reliable, and relatively inexpensive sources of energy. Additionally, the infrastructure for extracting and using fossil fuels is well-established, making it convenient for many industries and individuals to continue relying on them.

Coal beds form from the accumulation of plant material in swamps and wetlands over millions of years. The plant material is buried and subjected to heat and pressure, transforming it into coal. This process typically occurs in areas with high plant productivity and slow decomposition rates.

Burning coal produces carbon monoxide, a colorless and odorless gas that can be deadly if inhaled in a closed room. This gas can displace oxygen in the air, leading to suffocation. It is important to ensure proper ventilation when burning coal to prevent carbon monoxide poisoning.

Coal mines are usually deep inside the earth because coal deposits form over millions of years in layers of sediment. These layers are then buried deep underground by geological processes, making it necessary to dig deep to access the coal. Additionally, mining deeper coal seams can result in higher yields and better quality coal.

The country with the largest coal deposits is the United States, followed by Russia and China. These three countries collectively hold the majority of the world's coal reserves.

Brown coal, also known as lignite, is typically mined through open-cut or surface mining methods. In this process, the topsoil and overburden are removed to access the coal seams below the surface. Brown coal is then extracted using excavators, bulldozers, and other heavy machinery before being transported to a processing plant for further refining or combustion.

Basalt is an organic biogenic sedimentary rock that forms from the cooling of magma. It is not coal, sandstone, or conglomerate, which are sedimentary rocks formed from the accumulation and cementation of organic debris, sand particles, and mixed rock fragments respectively.

Salt is used to maintain electrical conductivity in the earth pit, ensuring proper grounding of electrical equipment. Coal, or charcoal, is sometimes mixed with the salt to improve the moisture retention capacity of the earth pit, helping to maintain a low resistance path for electrical current to dissipate into the ground.

Coal is extracted from the earth's surface through a mining process called surface mining. This involves removing the topsoil and rock layers to access the coal seams beneath. The coal is then extracted using heavy machinery like draglines, bulldozers, and excavators.

Coal is typically found in sedimentary rock layers within the Earth's crust, often formed from compressed plant material over millions of years. It is commonly mined from coal beds or seams that are buried beneath the surface. These coal deposits are found in different regions around the world where the conditions for coal formation were present.

In this day and age, with the constant increase in percentage consumption rates of coal, the supplies are beginning to run out. Since we have reached peak fossil fuels in only about a century, there's not many years left for fossil fuels. Based on these facts, it is safe to say that coal, the longest lasting fossil fuel, will run out in around 250 years, or less depending on growth rate of percentage consumption.

Basically it's cheaper. Coal was used but mining has gotten more expensive over the years also it gives off a lot of pollutants when burned, much more than natural gas, and so is banned for use in coal fires in most urban areas due to the high risk of smog.

In an ideal world:

* Deep mines have a small footprint although the treating and processing may leave piles of waste rock which should be covered wih dirt for reforestation. * Open pit mines may be converted to open grassy or forested areas.
