what are the various type of coal found in nature find the places where the coal mines each type of Poha located in our country
Answers
Answer:
Coal is the main source of energy in India as it fulfils almost 67 per cent of the total commercial energy consumed in the country. This fossil fuel is found in a form of sedimentary rocks and is often known as 'Black Gold'.
It is originated from organic matter wood. When large tracts of forests are buried under sediments, wood is burnt and decomposed due to heat from below and pressure from above. The phenomenon makes coal but takes centuries to complete.
Classification of Coal
Coal can be classified on the basis of carbon content and time period.
Types of coal on the basis of carbon content
Anthracite is the best quality of coal which carries 80 to 95 per cent carbon content. It ignites slowly with a blue flame. It has the highest calorific value. It is found in small quantity in Jammu and Kashmir.
Bituminous carries 60 to 80 per cent of carbon content and a low level of moisture content. It is widely used and has high calorific value. It is found in Jharkhand, West Bengal, Odisha, Chhattisgarh and Madhya Pradesh.
Lignite is often brown in colour. It carries 40 to 55 per cent carbon content. It is an intermediate stage which happens during the alteration of woody matter into coal. It has high moisture content so it gives smoke when burnt. It is found in Rajasthan, Lakhimpur (Assam), and Tamil Nadu.
Peat has less than 40 per cent carbon content. It is in the first stage of transformation from wood to coal. It has low calorific value and burns like wood.

Answer:The four types of coal include peat, lignite, bituminous, and anthracite, with anthracite being most desirable due to its high heat content. Coal was formed millions of years ago during the Carboniferous Period from ancient plants found in swamps and bogs.
