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 …
A study of Jharkhand's major coal mining district, Ramgarh, shows that mining activities are shrinking and about 50 percent of mines in the region are either "closed down" or temporarily discontinued because of various factors like unprofitability. ... and about 50 percent of mines in the region are either "closed down" or temporarily ...
The majority of coal mines encounter groundwater during mining. The water creates environmental, operational and stability problems. Water also creates stability problems with dams, dykes and spoil piles, particularly on dragline mining projects. This paper describes typical problems and presents recommendations to deal with water …

Key Findings. Heart disease is the leading cause of death in Appalachian coal-mining communities. Areas with mountaintop removal have significantly higher mortality rates from cardiovascular disease than other parts of Appalachia with similar levels of poor health, smoking and poverty. More than 700 additional deaths from heart disease occur ...
The positive influence is that coal mining improves the South African economy, expressive of impacts on export, domestic consumption, GDP, and employment. However, coal mining damages the ...
In 2020, methane emissions from coal mining and abandoned coal mines accounted for about 7% of total U.S. methane emissions and about 1% of total U.S. greenhouse gas emissions (based on global warming potential). Some mines capture and use or sell the coalbed methane extracted from mines.
This paper focus on mining environmental problems, especially the open pit mining,such as the loss of resources,air pollution,damage of landscape and ecology. 1.The environmental impact of mining 1.1 The environmental impact of open pit mining 1.1.1 the destruction of land resources The process of open-pit has a devastation impact on
IEA Clean Coal Centre – Environmental and other effects of coal mining and transport 9 1 Introduction Coal mining is an industry which has employed millions of people worldwide over centuries and has played a significant role in poverty alleviation, industrialisation and economic growth. However, during this time
3. Processing Chemicals Pollution. This kind of pollution occurs when chemical agents (such as cyanide or sulphuric acid used by mining companies to separate the target mineral from the ore) spill, leak, or leach from the mine site into nearby water bodies. These chemicals can be highly toxic to humans and wildlife. 4.
The environmental damage associated with mining is well-known, in terms of land clearing, ecosystem degradation, or water pollution. However, its effect on climate is less frequently considered.
Economically, surface mining is a cheaper option for extracting coal than underground mining. About two and a half times as …
Firstly, taking Jharia coal-field as a case study, the parameters/criteria affecting the environment have been identified. The parameters that are the most affected due to mining are air, water ...
Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all ...
Underground coal mining has a strong disturbance on surrounding rock strata, causing inevitable water inflow into mined spaces, which seriously affects safety production. Mine water disaster is regarded as one of the most critical problems in coal mining and, thus, has been a research hotspot in coal mining. This review focuses on …
The federal policy environment, the Great Recession, along with the falling prices of now abundant natural gas, diminished demand for coal after 2008. ... A common but under-researched question is the degree to which coal mining influences other local industries. For example, one of the hypothesized channels through which the natural …
Mining has played a part in the economic development of developed countries such as the USA, Canada and Australia. However, the mining economic growth connection varies considerably from that claimed in the historical analogy reasoning. It is not evident that these countries' historical experience applies to modern developing nations …
Permits require an environmental analysis of the mining operation and plans to ensure a stable post-mining landform (Skousen and Zipper, 2014). ... As the mining of coal and its influence in Appalachia wanes, its legacy is extensive. The region is transitioning to a future with far less economic support provided by coal, yet coal's …
1. Introduction. Energy is the driving force of national economic development. At present, the consumption of disposable energy, mainly oil, coal, and natural gas, is >90% in the world (Jo, 2018).Coal is the main energy resource in China, accounting for 61.8% of disposable energy consumption in 2016, and is expected to remain 58% by 2020 (Cao …
The coal fed Japan's growing steel industry, and in the decades of the 1950s, 60s and 70s, change was afoot. Switching from a majority of underground to open-cut mines in New South Wales and ...
2 days agoIn 2021, Inside Climate News reported that bankrupted coal mines left unreclaimed were among the potential long-term impacts of coal mining on the environment, with public concerns ranging from ...
Coal-mining affects the water environment by causing a drop in the groundwater table. Mining activities also pollute the water in addition to altering the …
Nuclear energy produces radioactive waste. A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
The long-term and continuous mining of coal deteriorates the natural environment as it sheds negative influences on the nearby water bodies and soil. 10 However, the regular disposal of millions of wastewater into the nearby water bodies is the main cause of pollution of water. 25 More specifically, the release of chemical particles …
The west of China is abundant in coal resources, with a weak ecological environment. Protecting water resources is particularly important as water is the material basis for supporting regional ecological environment and economic and social development (Wang et al. 2010; Fan et al. 2019).However, in recent years, massive exploitation of …
Numerous historical buildings exist in Shanxi Province, a major coal producing area in China, so there exist many overlapping areas between ancient wooden buildings and coal mining. Coal mining in overlapping areas will lead to surface subsidence, which will have an impact on historical buildings. Based on the distribution of …
The eco-environment quality (EEQ) of the study area is affected by both human and natural factors. Mining intensity and surface subsidence are the main human factors affecting the ecological ...
Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverable.This is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the …
Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the large-scale exploitation of coal deposits. Since the mid-20th century, …

The influences of coal mining on the large karst springs in North China. Environmental Earth Sciences, 64 (6) (2011), pp. 1513-1523.
Mining coal. Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, but others are deep underground.Modern mining methods allow U.S. coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour …
