Coal is extracted by different kinds of mining activities on the Earth's surface. The most common ones are surface mining and underground mining. Surface mining is done when coal is less than 200 feet below ground level. In this process, mineworkers have to remove all kinds of rocks and soil-forming the top layer.

 · Explanation: Coal was formed by the decomposition of large land plants and trees buried under the Earth about 300 million years ago. ... The slow process by which the dead plants buried under the Earth have become coal is called as carbonisation. Since coal was formed from the remains of the plants, it is called a fossil fuel.
