Coal mining disturbs surface ecosystems in coal mining subsidence areas. Based on the groundwater–surface composite ecosystem analysis, we constructed an ecological disturbance evaluation index system (18 indices) in a coal mining subsidence area using the analytic hierarchy process (AHP). Taking the Nalinhe mining area in …
Coal is South Africa's major primary energy source, and plays a significant role in supplying the chemicals and steelmaking industries. The benefits of coal production are relevant in the light of South Africa's development priorities of job creation and economic growth. Even so, primary metal production and coal-based power generation industries, through their …
Economically, surface mining is a cheaper option for extracting coal than underground mining. About two and a half times as much coal can be extracted per worker, per hour, than is possible with underground mining. The environmental impacts of surface mining are dramatic. The landscape is literally torn apart, destroying habitats …
Mining activities also give rise to the visual effects on the environment surrounding the mine including the release of methane into the atmosphere, the release of contaminated water and the generation of solid waste products. Fig. 6 schematically presents the environmental impacts caused by coal mining and coal utilisation processes [[9].
This study investigates the effects of coal mining on environmental sustainability in South Africa in relation to the moderating role of institutions. To achieve the study's objectives, the fully modified least square (FMOLS), dynamic least squares (DOLS), canonical cointegrating regression (CCR), Bayer-Hanck cointegration and Toda …
The paper enumerates the fact and fallacies of various health and environmental impacts of coal mining such as its impact on landform, soil, water regime, atmosphere, flora and fauna and human health.
The study recommends Environmental Impact Assessment (EIA) and land reclamations by the mining industry in order to minimise the effect of coal mining on the environment. Furthermore the living condition of the …
In 2008, the coal production has reached 2.72 billion tons. Long-time and intensive mining has caused spatiotemporal cumulative effects on soil, water, air environment, and ecosystem, which include ground subsidence, hydrodynamics change, land use change, soil pollution, air pollution, and ecosystem evolution etc.
A village was set up to support 15,000 miners working in the ruby mine near Ambatondrazaka, Madagascar. Photo: Pardieu et al. (2017). However, compared to many other industries such as agriculture, mining uses relatively small pockets of land, and the future of mining could move to using techniques that are arguably even less invasive on …
Environmental impacts. Coal surface mining has heavily altered the hydrological cycle and landscape of the Appalachia causing environmental degradation and contributing to ecosystem damages beyond repair. [11] Surface coal mining in the Appalachian has contributed to the destruction of over 500 mountain tops. [24]
The effects of mining coal on the environment. There are 2 ways to mine coal – Strip Mining and Underground Mining – both ways have their own impact to the environment and health. ... The negative effects of coal mining cannot be disputed: Destruction of Landscapes and Habitats: Strip mining also known as surface mining, involves the ...
While the environmental and health effects of coal are well understood, policymakers in newly industrializing countries often highlight the importance of coal for industrial development in ...
China is the largest producer and consumer of coal in the world. The extraction of coal is increasing intensively to meet the needs of the ever-increasing population and industries. However, coal mining has resulted in environmental changes, including deforestation, air, water, soil, and landform deterioration. This study …
Surface coal mining involves: removing parts or all of mountaintops to expose buried seams of coal, and. disposing in adjacent valleys the excess: "overburden" (rock above the coal seam), and. "interburden" (rock between coal seams). Overburden and interburden are disposed of in adjacent valleys because the broken rock will not all …
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, …
Mining, whether for fossil fuels or metals used in clean energy technologies, has serious environmental impacts, and it's hard to make apples-to-apples …
A coal surface mining site in Bihar, India A mountaintop removal mining operation in the United States. The health and 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 products.In addition to atmospheric pollution, coal burning …
The climate change impacts of mining are often not fully accounted for, although the environmental impact of mineral extraction more generally is widely studied. Copper mining can serve as a case ...
The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to the global environmental crises, such as poor air quality and climate change.
The EPA estimates that by 2012, mountaintop removal had destroyed 1.4 million acres of Appalachian forest. After the topsoil and upper portions of a mountain's rock have been removed, the remaining soil is incapable of producing native hardwood forest. Because the Surface Mining and Reclamation Act of 1977 does not require coal companies to ...
Mountaintop mining is a widespread practice in eastern Kentucky, West ia and southwestern ia. It involves removing forests, clearing topsoil and using explosives to expose buried coal. Excess rock is pushed into nearby valleys, disturbing habitats and blocking streams. Regulations require minimizing environmental impacts …
A Case Study on the effects of Coal Mining in the Environment Particularly in Relation to Soil, Water and Air causing a socio economic Hazard in Asansol-Raniganj Area, India IRJSS, 3(8), 39.
Abstract and Figures. This review presents a systematic synthesis of the various methods and measures that have been used to investigate the effects of coal mining in India. A total of 87 peer ...
The following environmental impacts due to coal mining are discussed in this paper. 1. Impact of coal mining on landform 2. Impact of coal mining on soil 3. Impact of coal mining on water regime
And a major environmental impact study on mountaintop mining published by the EPA in 2011 reported that storms can produce greater stream ... president of the West ia Coal Mining Association ...
Mining of coal around the world is being continued to meet the ever-growing energy demand. Mining involves extensive clearing of ground cover, change in …
The impact of coal mining on the environment varies in severity depending on whether the mine is active or abandoned, the mining methods used and the …
Table of Contents. 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 dirty.
While the environmental and health effects of coal are well understood, policymakers in newly industrializing countries often highlight the importance of coal for …
