In response to negative land effects of coal mining and the abundance of abandoned mines in the US the federal government enacted the Surface Mining Control and Reclamation Act of 1977, which requires reclamation plans for future coal mining sites. These plans must be approved by federal or state authorities before mining begins.
Areas in the Appalachia with coal surface mining exhibit greater rates of adverse health effects and reduced self-rated health in comparison to the national average. [1] In addition, studies from the National Institute for Occupational Safety and Health have concluded a high "relationship between surface coal mining jobs and the prevalence of ...
Some mining methods (lithium mining, phosphate mining, coal mining, mountaintop removal mining, and sand mining) may have such significant environmental and public health effects that mining companies in some countries are required to follow strict environmental and rehabilitation codes to ensure that the mined area returns to its original ...
Coal-seam fires have been slowly shaping the lithosphere and changing atmosphere, but this pace has become faster and more extensive in modern times, triggered by mining. [5] Coal fires are a serious health and safety hazard, affecting the environment by releasing toxic fumes; reigniting grass, brush, or forest fires; and causing subsidence of ...
Coal refuse, also known as coal waste, rock, slag, coal tailings, waste material, rock bank, culm, boney, or gob, is the material left over from coal mining, usually as tailings piles or spoil tips. For every tonne of hard coal generated by mining, 400 kg (880 lb) of waste material remains, which includes some lost coal that is partially ...
Coal ash contains many toxic substances that may affect human health, if people are exposed to them above a certain concentration in the form of particulate matter.So it is necessary to avoid situations in which employees working in coal-fired power plants or public members living close to coal ash landfills will be exposed to high coal ash dust concentrations.

For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. [1] The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation. Pulverized coal is a significant dust explosion hazard, as large quantities are suspended in air ...
