(DOC) COAL AND PETROLEUM Amitava

Underground mining is used to extract coal that is deep beneath the surface of the earth.Coal is processed in the industry to get useful products coke, coal tar and coal gas. Coke is an almost pure form of carbon that is used in the manufacture of steel and extraction of metals. Coal tar is a black, thick mixture of almost 200 substances.

Commonly used mining techniques to extract coal

As mining of coal depends on the depth and quality of the coal seams, different techniques are used to dig the deposits. Surface mining and deep underground mining are the two main methods of mining coal. Depth, density, and thickness of the coal seam are the factors that are taken into account while selecting the mining method for coal extraction.

Compare and contrast the process of mining coal and ...

Mining coal is a lot like mining any other metal or ore, it's just processed differently. Oil extraction is much different because oil is a liquid, not a solid like coal. There are many different ways of extracting it because oil is found in very diverse forms such as shale, liquid oil deposits, etc.
