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 …
In order to save coal-mining jobs in the East, the Clean Air Act was amended in 1977 to require equipment on all new coal-fired power plants to physically remove sulfur from the smokestacks after combustion, reducing the attractiveness of low-sulfur coal (all coal becoming "compliance coal"). This reduced the competitive threat to Eastern ...

One of the most obvious (albeit perhaps least harmful) environmental effects of coal mining is noise pollution. Coal mining is a loud, day- and night-long process that disrupts the lives of those in the surrounding communities, reduces the quality of life and can go on for decades. #11 Loss Of Wildlife. Coal mining requires a large expanse of ...

Planning for alternative regional economic futures to substitute for coal requires a clearer understanding of the upstream and downstream links of coal mining …
The negative effects of coal mining cannot be disputed: Destruction of Landscapes and Habitats: Strip mining also known as surface mining, involves the stripping away of earth and rocks to reach the coal underneath. If a mountain happens to be standing in the way of a coal seam within, it will be blasted or levelled - effectively leaving a ...
4.7 Captive Coal Mining Blocks 4.7.1 Under the Coal Mines (Nationalisation) Act, 1973, coal mining was mostly reserved for the public sector. By an amendment to the Act in 1976, two exceptions to the policy were introduced viz., (i) captive mining by private companies engaged in production of iron and steel and (ii) sub-lease for coal mining to ...
Coal is defined as having more than 50 percent by weight (or 70 percent by volume) carbonaceous matter produced by the compaction and hardening of altered plant remains—namely, peat deposits. Different varieties of coal arise because of differences in the kinds of plant material (coal type), degree of coalification (coal rank), and range of …
CWP, commonly called black lung, affects workers in coal mining. Silicosis can affect workers in many types of mines and quarries, including coal mines. Medical treatment cannot cure these diseases, so preventing them – through controlling respirable dust exposure – is essential.
Coal workers' pneumoconiosis (CWP), commonly known as "black lung disease," occurs when coal dust is inhaled. Over time, continued exposure to the coal dust causes scarring in the lungs, impairing your ability to breathe. Considered an occupational lung disease, it is most common among coal miners. ... Many industries such as mining ...

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.
Mining activities degrade the landscape and ecosystems by introducing new land uses that alter soil characteristics. Mapping of this degradation is critical, particularly in the context of environmental protection, including climate change research. Even though mining provides significant industrial and economic benefits to society, it also decreases …

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, coal has yielded …
