Each phase of coal's lifecycle (mining, disposal of contaminated water and tailings, transportation, washing, combustion, and disposing of postcombustion wastes) produces pollutants that affect human health. Communities in which coalmining or burning occurs have been shown to suffer significant health impacts.

Four case studies are presented on the topic of groundwater impact caused by coal mining. Zhao et al. investigated the impact of coal mining on both groundwater and surface ecosystems. It explores how coal mining activities can lead to disturbances in the natural balance of groundwater systems and surface ecosystems.

Second, the nature of coal fire emissions varies with the nature of combustion (Zhang et al., 2008). Coal mine fires tend to burn less efficiently and for longer periods than a coal-burning power plant, resulting in the release of a wide range of partially oxidised by-products including benzene, toluene, and xylene. Finally, the emission ...

Bitcoin mining emitted about 86 megatons of carbon, largely because of the dominance of fossil fuel-based energy in bitcoin-mining countries. The environmental impact of bitcoin mining fluctuates along with energy supply and demand in a country. When energy is inexpensive, the profitability of mining bitcoin goes up.
