History Coal was discovered in this region, first in Sohagpur Coalfield by a British geologist named Franklin in 1830.Sri Kamal Sharma, Resource Development in Tribal India: an Example of the Baghelkhand Plateau, p. 161, 164, Northern Book Center, After the First World War, the first attempts at coal mining failed, but around 1926 Burhar and Dhanpuri collieries were started. The Anuppur-Chirimiri line was opened in 1939 and mining operations were extended subsequently. Sohagpur Coalfield is a remnant in the Son basin of Gondwana deposition. The coalfield Sohagpur Coalfield is a part of Central India Coalfields. The latter is spread over the districts of Surguja, Koriya (both in Chhattisgarh), Shahdol and Umaria (both in Madhya Pradesh).

Coal Rank
Coal analysis techniques are specific analytical methods designed to measure the particular physical and chemical properties of coals. These methods are used primarily to determine the suitability of coal for coking, power generation or for iron ore smelting in the manufacture of steel. Chemical properties of coal Coal comes in four main types or ranks: lignite or brown coal, bituminous coal or black coal, anthracite and graphite. Each type of coal has a certain set of physical parameters which are mostly controlled by moisture, volatile content (in terms of aliphatic or aromatic hydrocarbons) and carbon content. Moisture Moisture is an important property of coal, as all coals are mined wet. Groundwater and other extraneous moisture is known as ''adventitious moisture'' and is readily evaporated. Moisture held within the coal itself is known as ''inherent moisture'' and is analysed quantitatively. Moisture may occur in four possible forms within coal: * ''Surface moisture'': wate ...

Surface Mining
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels. In North America, where the majority of surface coal mining occurs, this method began to be used in the mid-16th century and is practiced throughout the world in the mining of many different minerals. In North America, surface mining gained popularity throughout the 20th century, and surface mines now produce most of the coal mined in the United States. In most forms of surface mining, heavy equipment, such as earthmovers, first remove the overburden. Next, large machines, such as dragline excavators or bucket-wheel excavators, extract the mineral. The pros of surface mining are that it has a lower financial cost and is a lot safer than und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
