Coal - a Level Geography
Coal – Energy

Where are coal reserves?
Surface mining and deep underground mining are the two basic methods of mining. Many coals extracted from both surface and underground mines require washing in a coal preparation plant.
Coal Exploration - Coal reserves are discovered through exploration activities. 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. Once this has been confirmed, mining operations begin.

There are many ways to extract coal:

Modern surface mining
Area mining
Contour mining
Mountaintop removal mining
Underground mining

Which countries have most coal?

According to the BP Statistical review of world energy 2011, North America had the largest coal reserves with 120 billion tonnes of oil equivalent. The Middle East have very little amounts of coal.
It has been estimated that there are over 861 billion tonnes of proven coal reserves worldwide.
Coal reserves are available in almost every country worldwide, with recoverable reserves in around 70 countries. The biggest reserves are in the USA, Russia, China and India. After centuries of mineral exploration, the location, size and characteristics of most countries' coal resources are quite well known.

How long will coal reserves last?
It has been estimated that there are over 861 billion tonnes of proven (Reserves that are not only considered to be recoverable but can also be recovered economically. This means they take into account what current mining technology can achieve and the economics of recovery. Proved reserves will therefore change according to the price of coal; if the price of coal is low proved reserves will decrease) coal reserves worldwide. This means that there is

    Global energy reserves refers to the quantity of energy sources known with reasonable certainty to exist and can be recovered with the current technology at an economically viable cost. Saudi Arabia has the largest reserves of oil, but Russia has by far the largest gas reserves. However, assessing reserves and evaluating a true value as to how much there is left in the world is very difficult as different people and organisations have different personal motives.…

    Today, the three main fossil fuels that are in demand are oil, coal and natural gas. These fossil fuels are prevalent because they are efficient to burn, ship, and store based on high energy content. Fossil fuels also provide for our daily needs such as transportation, heating, cooking and electricity. Based on our current rates of consumption, we will use up the Earth’s store of fossil fuels faster than created therefore making it a nonrenewable source of energy. After fossil fuels are created and depleted, they cannot be replaced in our civilization. This extremely long process takes thousands of years and if we were to replenish the depleted fossil fuels it would take millions of years.…

    Resources and reserves are similar in that the both benefit humanity. Resources are materials that can be used to satisfy human needs, or used as support. Reserves on the other hand are known deposits with the ability to extract the available material economically; the size of these reserves is not always known or defined. Resources could be possible reserves but they are not exactly economically viable. When estimating the influence of reserves and resources for commodities some technological, economical, environmental and political factors must be taken into consideration. In technology for example extraction methods, development, processing, shipping and distribution are some main areas to pay attention too. These technological impacts can affect the cost and the feasibility of recovery, this referring to any externalities, costs aside from the established price for the commodity. Linking to this we see the economical factors, which include commodity price, supply and demand, cartel, and price controls. Also any changes in price, regulations, or politics may influence resource recovery since the political and human factors involved are government/political stability; crime control; industrial nationalization; perception and cultural value.…

    It is the most reliable source of energy available. There is estimated to be around 26 billion tons of coal still remaining in Kentucky. That’s a lot of coal, but it doesn’t seem that it’s going to be mined anytime in the near future. Due to all of the regulations on the coal industry and the closing of mines all across the state it’s becoming harder and harder to extract this coal. These regulations hit Kentucky’s coal industry hard. They are no longer able to produce coal on the level that they used to. Coal production has dropped dramatically in the last ten years. In 2015 Kentucky produced 61.4 million tons of coal, a decrease of 20.7% from 2014. The energy that coal produces can be used in many different ways. The most significant use of coal is in electricity generation. Coal provides 87% of Kentucky’s electricity as of 2015. The cost of electricity in Kentucky is also the fifth lowest in the country at an average of 8.03 cents per kilowatt-hour. Coal helps provide us with cheap and affordable electricity to help keep our lights…
