Mar 23, 2018 · 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. I'll focus on the liquid since that is ...

The process of mining is simple, and the tools are of the rudest. They are pick and shovel, bar, hand and machine drills,—the latter an auger, turned by a crank,—and powder and squibs. The coal is loosened or "cut " from the face by blasting; the pick is only used to knock down loosened pieces from the roof and sides, to break up the ...

Coal mining increases the risk of loosening top soils into streams and waterways and the sediments pollute our water and can smother plant life downstream and even kill fish. Coal has traces of sulfur and nitrogen. When burned, these are released into the atmosphere. While these chemicals are floating in the air, they can mix with water vapor ...
