As water drains from the mine, the acid moves into the waterways; as long as rain falls on the mine tailings the sulfuric-acid production continues, whether the mine is still operating or not. [15] Also waste piles and coal storage piles can yield sediment to streams.
Water pollution is another factor that is being damaged throughout this process of mining coals, the ashes from coal is usually carried away in rainwater which streams into larger water sites. It can take up to 10 years to clean water sites that have coal waste and the potential of damaging clean water can only make the filtration much more ...
Machinery trying to mine the coal may not be able to reach the displaced seam, if the displacement is too large. Coal mines use a combination of boreholes and high-resolution seismic reflection data to identify the larger faults and avoid the most faulted areas at the mine planning stage. [1]
Coal mining has been a very dangerous activity and the list of historical coal mining disasters is long. In the U.S., 104,895 coal miners were killed in mine accidents since 1900, [31] 90 percent of the fatalities occurring in the first half of the 20th century. 3,242 died in 1907, the worst year ever; in 2020 there were five.

Coal ash, the substance that remains when coal is burned to generate electricity, contains a toxic mix of mercury, cadmium, arsenic and other heavy metals. EPA moves to crack down on dangerous ...
Coal mining, coal combustion wastes, and flue gas are causing major environmental damage. [143] [144] Water systems are affected by coal mining. [145] For example, the mining of coal affects groundwater and water table levels and acidity.
The U.S. Bureau of Mines was created in 1910 to investigate accidents, advise industry, conduct production and safety research, and teach courses in accident prevention, first aid, and mine rescue. The Federal Coal Mine Health and Safety Acts of 1969 and 1977 set further safety standards for the industry.
The contamination can be traced back to an incident in October 2000. A local subsidiary of Massey Energy was mining coal in the area for energy production. The byproduct of the energy production process is a black sludge substance which contains high levels of arsenic, lead, mercury, and other industrial pollutants. [13]
