Stratum
In geology and related fields, a stratum (: strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and '' lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

Coking Coal
Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or petroleum in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude petroleum in petroleum refineries. Coke may also be formed naturally by geologic processes.B. Kwiecińska and H. I. Petersen (2004): "Graphite, semi-graphite, natural coke, and natural char classification — ICCP system". ''International Journal of Coal Geology'', volume 57, issue 2, pages 99-116. It is the residue of a destructive distillation process. Production Industrial coke furnaces The industrial production of coke from coal is called coking. The coal is baked in an airless kiln, a "coke furnace" o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
