Coal and Air Pollution. Air pollution from coal-fired power plants is linked with asthma, cancer, heart and lung ailments, neurological problems, acid rain, global warming, and other severe environmental and public health impacts. Coal has long been a reliable source of US energy, but it comes with tremendous costs because it is incredibly China’s total coal production in 2021 exceeded 4.13 billion tons, 52% of the world’s total. Coal gangue, a solid waste of coal mining accounts for 15–20% of coal production, when directly discharged on the ground surface as waste heaps, it occupies large areas of land and cause environmental pollution.

Coal and Other Mining Operations: Role of Sustainability

Pollution from Coal Mining. The process of coal excavation causes deterioration of the original morphological and pedological structure of the terrain and soil, and results in the release of harmful substances and/or mineral dust into the air.Coal left in the ground can catch fire, and mine fires are difficult to control, with some burning for decades or even centuries, creating a major source of air pollution. The use of explosives, such as in mountaintop removal, releases carbon monoxide (CO). Dust and coal particles stirred up during the mining process, as well as soot releasedAir pollution from coal mines Global Energy Monitor

Dust pollution in cold region Surface Mines and its prevention

Since more than 90% of China's open pit coal production comes from cold regions, the dust pollution in winter stope is severe. Due to the extended period of severe cold, less precipitation, and high evaporation in the mining area, water spraying is difficult in winter (Luo et al., 2021a). In addition, dry dust reduction techniques are also moreChina has the largest coal production in the world due to abundant resource requirements for economic development. In recent years, the proportion of opencast coal mine production has increased significantly in China. Opencast coal mining can lead to a large number of environmental problems, including air pollution, water pollution, and Life cycle assessment of opencast coal mine production: a

Compared to the entire network, from the perspective of the influence, the system of measurement for keywords in Fig. 4 and Table 3 showed that keywords of coal mining, gold mining, heavy metals, adsorptions, sedimentations, and environmental pollution are more commonly used keywords words during the period (i.e., 2001 to 2020) in MWWT Coal is abundant, comparatively cheaper than other fossil fuels, and is widely used. Coal produces carbon dioxide, which is a greenhouse gas responsible for climate change. Burning fossil fuels causes air pollution.

Soil pollution in Indian coal mines, available remediation

Soil pollution due to various coal mining activities: (a and b) shows the dumping of waste and discarded rocks, (c and d) represent the uncovered transportation of coals and waste rocks; (e) displays the alteration of elegant landscape, (f) depicts sediment pollution in water catchment areas, and (g and h) illustrates the dumping of mine spoils Waste from the Mining Process. Ore is mineralized rock containing a valued metal such as gold or copper, or other mineral substance such as coal. Open-pit mining involves the excavation of large quantities of waste rock (material not containing the target mineral) in order to extract the desired mineral ore.Mining and Water Pollution — Safe Drinking Water Foundation

Coal Mining Activities Driving the Changes in Microbial

Coal mining can cause groundwater pollution, Coal mining is mainly carried out on the tunneling panel of the coal roadway. During the tunneling process, S 3 sandstone groundwater would flow out from the roof and floor of the coal roadway, resulting in a new water–coal/rock reaction.Despite the trend of a transition to “clean” energy, the coal industry still plays a significant role in the global economy. The constant need for raw materials and energy for production leads to an environmental crisis—an increase in the content of greenhouse gases in the atmosphere, especially in the mining regions.

Coal Education

Coal is a nonrenewable fossil fuel that is combusted and used to generate electricity. Mining techniques and combustion are both dangerous to miners and hazardous to the environment; however, coal accounts for about half of the electricity generation in the United States.ABSTRACT. In order to solve the serious dust pollution problem in mining and loading process of burnt rock open-pit coal mines, a dust suppression technology was proposed to investigate the compound dust suppressant with four functions of wetting, coagulation, moisture absorption, and moisture retention, and improve the hydrophilicity and dust Full article: A research on dust suppression mechanism and application
