Pollution leaching from coal ash storage and landfills into groundwater and several large impoundments of coal ash that ruptured are environmental concerns. Reducing the environmental effects of coal use. The Clean Air Act and The Clean Water Act require industries to reduce pollutants released into the air and water.

Possibly one of the scariest environmental effects of coal mining is the threat of acid rain. The high acidity of AMD remains in the water supply even through evaporation and condensation, which enables it to stay in the atmosphere and eventually return in the form of "acid rain," thus perpetuating the cycle of pollution.

The coal industry has a significantly negative environmental impact on the land, water, and air. It is responsible for producing pollution such as ash, sludge, slurry, arsenic, mercury, uranium, and other heavy metals that pollute the air and waterways. Additionally, coal processing has a negative effect on human health.

Air pollution from coal-fired power plants. According to the Union of Concerned Scientists, in an average year, a typical coal plant (500 megawatts) generates the following amounts of air pollutants: 3.7 million tons of carbon dioxide (CO 2 ), an amount equivalent to chopping down 161 million trees.

However, extraction of both series of coal ash with KCl showed expected behavior, i.e., previous extraction of coal ash with river water has decreased the amount of leached ion-exchangeable iron, witnessing possible leaching of iron during transport processes.

Coal mining operations are a well-known source of water pollution (Tiwary 2000; Younger 2004).Coal mine drainage can escape, or be discharged, to local waterways causing contamination of surface waters to levels that degrade stream ecosystems (Jarvis and Younger 1997; Pond et al. 2008; Wright et al. 2017).One well-known form of water pollution that can be …

In the process of coal gangue surface accumulation and underground filling disposal, the heavy metals contained in coal gangue will inevitably precipitate out and migrate, which will cause serious environmental pollution. Seventy-five gangue samples of different geological ages are obtained from 25 coal mines in China. The contents of Hg, Pb, Cd, Cr, As, Cu, Zn, Mn, Se, …

Pollution from coal utilization. Coal utilization is associated with various forms of air pollution.During the incomplete burning or conversion of coal, many compounds are produced, some of which are carcinogenic.The burning of coal also produces sulfur and nitrogen oxides that react with atmospheric moisture to produce sulfuric and nitric acids—so-called acid rain.

the coal as a fuel and cause environmental problems in its use. The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat coal deposits are mined by surface processes, which are generally less costly (per ton of coal) than underground mines of similar capacity. Strip mining is one of the
