Due to its high energy generation potential, coal is widely used in power generation in different countries. Although, the presence of carbon, hydrogen and sulfur in coal facilitates the energy generation in coal combustion, some pollutants including COx, SOx, NOx, particulate matter PM and heavy metals are accumulated in air and water and lead to severe environmental and health impacts as a

Since 1980s, the disposal technique for coal mining wastes has been changing and in many instances the wastes are now transported directly to subsided land as a fill to enable the reuse of that land. Thus, today, both coal mining waste dumps from the past and filled subsided lands are in existence.
History. Mining waste is one type of special waste When EPA proposed regulations for managing hazardous waste under Subtitle C of Resource Conservation and Recovery Act RCRA on December 18, 1978 43 FR 58946, the agency deferred hazardous waste requirements for six categories of wastewhich EPA termed special wastesuntil further study and assessment could be completed to
The origin of mining and mineralprocessing wastes is closely related to the formation of the target resource or minerals. For example, many coal deposits exist in subsided regions resulting from mountain formation hence, the overlays of coal resources are generally not very thick and consist of relatively inactive sedimentary rocks.
The environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and fluegas desulfurization sludge, that contain
