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 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 ...
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 ...
Consequently, mining of minerals in general and coal in particular has become the prime focus. It helps to generate revenue, augment industrialisation and promote employment opportunities in India.
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. While the world is rejecting fossil fuels, deep in the heartland of the central Indian mining belt, coal extraction is still considered the cheapest ...

to minority status in coal mining, India launched commercial coal mining via coal mine auctions in 2020. PM Narendra Modi on June 18, 2020 launched the auction process of 41 coal mines for commercial mining with an aim to achieve selfsufficiency in meeting energy needs and boost industrial development. India concluded its first
The overall process of coal exploration and mining involves six separate but interdependent and overlapping components: • Exploration: the identification and geological assessment of a new coalbearing area; • Mine Design: the design and economic evaluation of the most appropriate mining operation to make use of the coal in that area;
The mining industry in India is a major economic activity which contributes significantly to the economy of gross domestic product (GDP) contribution of the mining industry varies from % to % only but going by the GDP of the total industrial sector, it contributes around 10% to 11%. Even mining done on small scale contributes 6% to the entire cost of mineral production.

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.

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.
(underground and surface) and coal liquefaction only can do coal mining in India for captive consumption. The Central Government, a Government company (including a State Government company), a Corporation owned, managed and controlled by the Central Government can do coal mining without the restriction of captive use.
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.
Since the 1980s, rathole mining is the primarily practiced mining technique in Meghalaya in which deep vertical shafts with narrow horizontal tunnels of 3 to 4 feet diameter are dug and miners are sent down to extract coal till 100 to 150 metre and in some case even more than that.
