Fossils and amber may be found in coal. The conversion of dead vegetation into coal is called coalification. At various times in the geologic past, the Earth had dense forests in low-lying wetland areas. In these wetlands, the process of coalification began when dead plant matter was protected from biodegradation and oxidation, usually by mud or acidic water, and was converted into peat. This trapped the carbon in immense peat bogsthat were eventuallyCoal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses,Coal Extraction and Processing is a mineral removal and refinement process in which coal (black or brownish-black sedimentary rock composed mostly of carbon and hydrocarbons that contain energy that is released when burned) is removed from the Earth and treated for further use.Coal mining and transportation - U.S. Energy Information,,Jun 01, 2020· Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.
