Where do we find coal?
The largest coal reserves are in the United States, Russia, China, Australia, and India. In the United States, coal is mined in 25 states and three major regions. In the Western Coal Region, Wyoming is the top producer—about 40% of the coal mined in the country is extracted in the state.
Which coal is mostly found in India?
What layer do we find coal in?
Coal deposits are found in sedimentary rock basins, where they appear as successive layers, or seams, sandwiched between strata of sandstone and shale. There are more than 2,000 coal-bearing sedimentary basins distributed around the world.

Which is the biggest coal mine in India?
What are the 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite.
How many years of coal is left?
Based on U.S. coal production in 2019, of about 0.706 billion short tons, the recoverable coal reserves would last about 357 years, and recoverable reserves at producing mines would last about 20 years. The actual number of years that those reserves will last depends on changes in production and reserves estimates.
How deep is coal usually found?
Coal that occurs at depths of 55 to 90 m (180 to 300 ft) are usually deep mined, but in some cases surface mining techniques can be used. For example, some western U.S. coal that occur at depths in excess of 60 m (200 ft) are mined by the open pit methods, due to thickness of the seam 20–25 metres (60–90 feet).
Which coal is best quality?
Which state is largest producer of coal in India?
Jharkhand, Odisha, Chhattisgarh, West Bengal, Madhya Pradesh, Telangana and Maharashtra accounted for 98.26% of the total known coal reserves in India. As on 31 March 2018, Jharkhand and Odisha had the largest coal deposits of 26.06% and 24.86% respectively.
How is coal formed?
Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Is Coal still being formed?
The process of coal formation is still taking place today, says Bailey. “The precursor to coal is called peat, and that is just uncompressed plant matter.” Peat accumulates in wet swampy environments known as mires, and that process is taking place today in areas such as Indonesia and even the Antiplano in the Andes.
How is coal mined today?
Open-cut mining is possible because coal seams are close to the surface. Such mining is cheaper than underground mining and enables up to 90% recovery of the resource. … The surface rock (called overburden) covering the coal is then blasted with explosives and removed by excavators.
What is coal chemical formula?
It contains mostly methane, a simple chemical with the formula CH4. That means there are four hydrogen atoms for each carbon atom, the maximum a single carbon atom can accommodate.
