Uses of Coal. It is mainly used to generate heat and electricity. It is used in s and in industries to accomplish various tasks. It is the cheapest source of power fuel. The iron and steel industry depends heavily on fossil fuel for energy. It is also used to produce useful products such as coke, tar, and coal gas.

Mining is an important activity for India. With 3527 mining leases for 40 major minerals, extending a total lease area of roughly 315,986 hectares, India is a major producer of crucial minerals such as chromite, iron ore, coal, and bauxite, among others. Mining contributes to per cent of the Gross Domestic Product (GDP).

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 ...
The process of the auction of 41 coal mines in India has commenced as part of the Centre's Atmanirbhar (selfreliant) India campaign on June 18. It is for the first time that coal mines in India are being opened for commercial mining.

As per the latest data released by the Ministry of Mines, Government of India, mineral production in India rose by per cent yearonyear in May 2022 led by a sharp jump in the output of coal, gold, phosphorite, and bauxite. India's mining sector has vast potential given it produces 95 minerals, including 10 metallic and 23 nonmetallic. The Government is keen on prioritizing coal and ...
Despite government's repeated assertions for the sustainable mining extraction and development of rural and tribal communities living near the vicinity of mining areas, these have not been converted into implementable solutions. The natural resources from rural and tribal areas are being exploited to meet the everincreasing requirements and aspirations of the affluent groups. With the above ...
Coal is one of the most essential resources of a country. It is widely used for power generation and as a raw material in the industries. 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 opencast methods.
For India, coal is here to stay for the near future. At the same time, India is pursuing renewable energy, with a new pledge at COP26 to install 500 gigawatts of renewable power capacity by 2030 ...
A resurgence in India's hunger for coal could mean peak consumption is years away. The use of the fuel for power generation is seen growing at the fastest pace in over a decade this year.
Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
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.
Coal production of India. Coal in India has been mined since 1774, and India is the second largest producer and consumer of coal after China, mining million metric tons ( million short tons) in FY 30% of coal is imported. Due to demand, supply mismatch and poor quality with high ash content, India imports coking coal to meet the shortage of domestic supply.
The waste material from coal mining in India comprises mainly of sandstone, bands of clay and other metamorphic rocks. The sandstone ranges from coarse grain to fine grain. ... Blast furnace slag is generated during the melting process in steel making operations. It is very as a cementitious binder in road construction. It is very commonly used ...
Strip Mining. In strip mining, the first step is to strip off the vegetation and soil in the vicinity of the surface to be mined for coal. The large intermediate layer of sediment and rock,, the 'overburden' is then blasted and removed using large trucks. Once exposed, the underlying coal seam is excavated in strips and transported out ...
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.

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 ...
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.

It is cheaper than underground coal mining. There are three types of surface mining strip mining, where explosives are used to remove the top layers; open pit mining when a pit is dug; and MTR mining where a whole mountain summit is destroyed. Underground mining is performed when the coal is deeper than 300ft below ground level.
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.
