  3. Coal mining • Mine workers use surface mining to reach coal beds close to Earths surface. • Surface mines produce more than two-thirds the coal in the US • Once mined, coal is usually burned for heat or to make electricity • The average coal miner is 45 years old and has 20 years of experience

  4. Disadvantages of coal • Burning coal can create a significant pollution problems • It cannot be recycled • Burning fossil fuels releases carbon dioxide, a powerful greenhouse gas • When people dig for coal, many trees are cut down • Coal is nonrenewable and fast depleting • Mining of coal leads to irreversible damage to the adjoining environment

  5. Advantages of coal • Coal is one of the most abundant sources of energy, more so than oil and natural gasses • Coal can be found in lots of places in the world and there is still plenty in the UK • Coal can be easily transported to the power stations • Burning coal can produce useful by- products • Coal is a relatively cheap energy source • Widely and easily distributed all over the world

  6. How coal is mined • Mining- the process of moving coal from the ground • Types of mining: underground mining surface mining • When coal is less than 125 feet under the surface it is mined through surface mining • When it is deeper it is removed by underground mining

  7. Surface mining • Surface mining is used wen coal is located close to the surface • In 2005 there were six surface mines in Illinois • The surface mine produced 3,800,000 tons of coal • Surface mining deals with soil and rock mine techniques where levels of ground are removed and as mineral deposits are exposed and processed • Surface is the opposite of underground mining
