Coal mining is good because it is used to get a very important natural resource, coal. Coal is used in many things and without coal mining we could not do those things.
The history of coal mining goes back thousands of years. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today.
Fires connected to coal mining create underground burning that can be difficult to remove. Established communities sometimes need to move to avoid the pollution of the coal mines as well, displacing people from their homes. The advantages and disadvantages of coal require a balance of current power needs and environmental management.
Coal is primarily used as fuel to generate electric power in the United States. The coal is burned and the heat given off is used to convert water into steam, which drives a turbine. In 2012, about 39 percent of all electricity in the United States was generated by coal-fired power plants, according to the U.S. Energy Information Administration.
In 1700, five-sixths of the world's coal was mined in Britain. In Australia, black coal was first discovered in Newcastle in 1791 and coal mining and exports commenced in 1799. These early coal mining activities made a significant contribution to the progress of European settlement in Australia.
