Coal mining in India. India is rich in ancient coal fields like Gondwana coalfields (250 million years old) and tertiary coalfields (1560 million years old). Coal mining was started during the rule of the East India Company in 1774 in the Raniganj coalfield along the western bank of the Damodar river. To increase coal production, the focus of ...
Coal mining, especially opencast mining and the evacuation of coal, requires large tracts of land for extraction processes, industrial purposes such as thermal power plants and captive plants, as well as ancillary processes such as OB dumps, pipelines, railway lines, and public works.
underground mines in the earth crust. Coal mining is one of the most illegal activities going on in the country. At the same time it totally neglects the role of EIA in its preoperational, during mining and post operational plans. Here various case studies of coal mining are done and the impact of coal mining to the environment is looked into with
The extraction process of CBM involves the dewatering of coal seams, enabling the release of trapped methane gas [1].However, one of the primary challenges encountered during CBM production is the significant amount of water that accompanies the extracted gas [2].This water, known as produced water, poses a major problem in terms of treatment, disposal, and potential environmental impacts.
The first segment of the coal beneficiation process involves feeding the ore through a roll crusher and then sizing screen. ... Mountaintop removal is a form of surface mining where the tops of mountains are dynamited and removed to access coal seams. Underground mining, or deep mining, is necessary when the coal is roughly over 90 metres below ...
The critical purpose of this study is to identify the lacunae in the clearance and approval process due to the fragmentation of environmental and mining laws administered by multiple agencies for coal mines in India. The authors have used doctrinal and qualitative methods to present their findings for this case study.
The technique of manual drilling that finally rescued the workers is known as rat mining. Rat mining or rathole mining is the process of narrow tunnel excavation by manually digging through. The ...
outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the top of mountains is ...
Abstract Soil pollution due to coal mining and its associative activities has become a serious environmental concern in India. The byproducts of coal mining are often disposed directly to the bare lands, significantly altering the characteristics of soil up to a considerable extent. These stacks of discarded rock wastes under the influence of various geological agents, viz., wind, running ...
"The worst part is that in order to open up more coal, the government is allowing mining in dense forested areas. Forests are sinks of carbon dioxide so if you are getting new coal to burn by ...
"Rat mining" is a primitive, hazardous and controversial method used in India mostly to remove coal deposits through narrow passages. The name comes from its resemblance to rats burrowing through ...
In the 2021 Monsoon session of the Parliament, the CBA Act is set to be introduced with three new amendments via The Coal Bearing Areas (Acquisition and Development) Amendment Bill, 2021. Read together, these three amendments are set to make the process of acquiring land and allotting coal fields to mining companies or the State more simple.
Coal is on the rise in India: despite the devasting impacts of the climate crisis, the awareness for land and forest rights, and political talk of a coal phaseout. In this article, we demonstrate that despite the renewablesled rhetoric, India is in the midst of a transition to (not away from) greater use of coal in its fossil energy system ...
Coal mining in India has primarily been driven by the need for energy domestically. About 55% of the current commercial energy use is met by coal. The power sector is the major consumer of coal, using about 80% of domestically produced coal. ... CAG recommended that the allocation process should be made more transparent and objective, and done ...

The phaseout dilemma . Domestic production of coal meets most power demand in India, eliminating the need of nonessential imports. With extreme weather events such as this year's scorching summer followed by a dry hot spell in August, India's demand for more electricity also put pressure on its coal much so, the environment ministry gave coal mines permission to boost ...

Coal mining is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity.
During the coal mining process, a significant amount of coal wastes is produced, including (1) mining wastes, (2) washery wastes, and (3) secondary processing wastes. Since 2017, the annual global CMWs are estimated to be 315 million tons for underground coal mining. This results in the disposal of a considerable volume of wastes at waste dumps.
India ranks third in coal production. However, the country has to import coal in order to meet the rising demand for coal. In India, coal mining is conducted using two methods: underground and ...
Coal mining and its unfavourable consequences have generated global attention. It has further stimulated the paradoxical debate of development and desolation in the contemporary scenario. Since the coal resources are profusely available in India and it is comparatively less expensive, the country has been largely relying on it for its essential and nonessential consumption needs. Coal ...

Auction/Allotment. Coal mining in India has been metamorphosed as far as the policy framework is concerned. From an earlier restrictive model, we have moved on to granting coal mining blocks pursuant to a competitive bidding process, and from prescribing specific enduse to permitting commercial sale of coal. The auctionbased regime introduced ...
The Real Cost of Coal Extraction in India. This report by Aditi Rajagopal is part of a series on the environment and climate change funded by Deutsche Welle, Germany's international broadcaster.
