effects of mining on the environment 1. It destroys forest and wetlands. 2. It may mean that you have to cut down lots of trees just to get to the spot that has all the gold or iron ore. 3. Many mine require tailings dams to prevent waste being washed into the rivers. Unethical miners can dispense with the dams‚ to save costs‚ resulting in massive pollution downstream. In other cases‚ the tailings dam can overflow‚ and even breach‚ during periods of heavy rain. 4. Underground coal mining

energy now is coal. Coal is the most abundant fossil fuel in the world (Berg and Hager 2007). Coal is used by the utilities companies to produce electricity. Coal is usually mined. There are two types of mining methods used with coal; one is surface and the other is sub-surface (underground). In the United States surface mining is used to obtain approximately sixty percent of all coal mined in the United States. Sub-surface‚ underground‚ accounts for the other forty percent of coal mined in the United
