Decades of unabated coal mining can irreversibly change the character of an area and that is the story of Raniganj Coalfields, India's oldest coalfield area spread over West Bengal and parts of Jharkhand. Although mining started in this area in 1774, environmental degradation worsened when open-cast mines made their appearance 30 years ago.
Coal mining's effect on the environment reaches beyond the atmosphere — the Earth also feels its effects. Land: Coal mining can lead to soil erosion and dust, and it disturbs large tracts of land. Water: Acid mine drainage, a metal-containing water that is formed by the chemical reaction between water and rocks containing sulphur-bearing ...
Across the United States, coal mining is destroying wildlife habitat, polluting local water resources and dirtying our air. In the case of mountaintop removal mining, coal companies are exploding entire mountains to reach buried seams of coal and then filling valleys with the rubble, burying hundreds of miles of stream forever.
companies are now working towards "clean coal" strategies, which aim to reduce environmental impacts. Keywords: pollution, coal mining, development, displacement, global warming. GJHSS-B Classification: FOR Code : 850201 . Susceptible Development Impact of Coal Mining on Environment in India. Strictly as per the compliance and regulations of:
Mining leaves an eyesore on the land. By ripping open mountains to extract the ores within, it sometimes leaves areas unusable after the mining companies have left. We can't go on this way, and politicians agree. It's why mining companies are working to reduce the environmental impact of mining through green mining processes.
However, mining also has severe negative effects on the environmental system, including humans, animals, plants and also aquatic life. In order to mitigate the adverse effects of mining, it is crucial that we reduce our consumption levels. Industries only mine on large scale since our consumption levels lead to such high demand.
Coal mining increases the risk of loosening top soils into streams and waterways and the sediments pollute our water and can smother plant life downstream and even kill fish. Coal has traces of sulfur and nitrogen. When burned, these are released into the atmosphere. While these chemicals are floating in the air, they can mix with water vapor ...
Hindalco is planning very aggressively to expand its mining business. All mining activities are now controlled by the newly formed Hindalco Mining Vertical. I have been functioning as Chief Resource Geologist for our newly formed Mining Vertical to look after all the 20 bauxite and 4 coal mines in India with effect from 20th March, 2017.
Steps in coal extraction Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Steps in coal extraction, quarry, aggregate, and different kinds of minerals.
As the world is moving away from coal due to its detrimental impacts on climate change, it seems questionable that we are expanding our coal mining. In this article, Archana Soreng and I seek to explicate why this decision is so detrimental: 1. Air Pollution kills 1 out of every 8 Indians. Coal is responsible for majority of this.

Coal Combustion Residues (CCRs) are a collective term referring to the residues produced during the combustion of coal. It includes fly ash, bottom ash, boiler slag, and fluidized bed combustion ash and other solid fine particles. In India, presently coal based thermal power plants are releasing 105 MT of CCRs which possess major environmental ...
The Dollar Business Bureau. India's thermal coal imports through 12 major public sector ports increased 1.3% at 18.33 million MT during April-May this year, from 18.09 million MT in the corresponding period previous year, as per the data released by Indian Ports Association on Wednesday.
Also the rate of clean energy cess on production and import of coal, lignite and peat increased from INR50/t to INR100/t. Impact. Although the government of India claims to have aligned duty rates of various types of coals by rationalizing BCD and CVD to avoid ambiguity, the decision is likely to have some negative effect on Indian steel, power and other coal consuming industries.
