Coal Mining In India
Coal in India has been mined since 1774, and India is the second largest producer and consumer of coal after China, mining in FY 2024-25. Around 15% 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. State-owned Coal India had a monopoly on coal mining between its nationalisation in 1973 and 2018. Most of the coal is burned to generate electricity and most electricity is generated by coal, but coal-fired power plants have been criticised for breaking environmental laws. The health and environmental impact of the coal industry is serious, and phasing out coal would have short-term health and environmental benefits greatly exceeding the costs. Electricity from new solar farms in India is cheaper than that generated by the country's existing coal plants. History The Indira Gandhi administration of India nationalized coal mining in phases – coking coal mines in 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Indira Gandhi Ministry Of India
The second (symbol: s) is a unit of time derived from the division of the day first into 24 hours, then to 60 minutes, and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units (SI) is more precise: The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. As the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. The definition that is based on of a rotation of the earth is still used by the Universal Time 1 (UT1) system. Etymology "Minute" comes ...

Steam Locomotives
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Damodar River
Damodar River (Pron: /ˈdʌmoˌdaː/) is a river flowing across the Indian states of Jharkhand and West Bengal. The valley is rich in mineral resources and is known for large-scale mining and industrial activity. It was also known as the Sorrow of Bengal because of the ravaging floods it caused in the plains of West Bengal. The construction of several dams on the Damodar and its tributaries has helped control some of the flooding. Etymology Damodar means "rope around the belly", derived from Sanskrit दाम (dama) "rope" and उदर (udara) "belly". Damodar is also another name given to the Hindu god Krishna because his foster-mother, Yashoda, had tied him to a large urn.Chattopadhyay, Akkori, ''Bardhaman Jelar Itihas O Lok Sanskriti'' (History and Folk lore of Bardhaman District.), , Vol I, pp. 21- 26, Radical Impression. Course The Damodar is a rain-fed river. It originates in Khamarpat Hill on Chotanagpur Plateau in Jharkhand. It travels before joining the Hooghly Ri ...

History Coalmining in India first started in the Raniganj Coalfield. In 1774, John Sumner and Suetonius Grant Heatly of the British East India Company found coal near Ethora, presently in Salanpur community development block. The early exploration and mining operations were carried out in a haphazard manner.Akkori Chattopadhyay, ''Bardhaman Jelar Itihas O Lok Sanskriti'' , Vol I, pp. 46-51, Radical, 2001, Regular mining started in 1820, led by an agency house, Alexander & Co.

Suetonius Grant Heatly
Suetonius Grant Heatly (sometimes spelled as ''Heatley''; 1751–1793) was a judge employed by the British East India Company and, with John Sumner, established what is considered to be the first coal mine in India.Manners & Williamson (1920), pp. 180–181. Heatly was born in Newport, Rhode Island, in what is now the United States, to a family that had a Scottish heritage.and was loyal to the British Crown. That loyalty caused them to move to England around the time of the American Revolution. His connections and ability were useful in his career with the East India Company, which he joined in 1766 and for which he held various offices. Grant and his colleague, Sumner, saw potential in the extraction of coal in India and attempted to capitalise on that and their relationship with the East India Company, which they envisaged as being a significant purchaser. Their project involved several mine workings, the precise location of which has been debated. It was beset by problems, incl ...
