Although the United States has the large coal resource described in the earlier chapter, maybe as much as four trillion tons, the important thing topic for policy makers is the amount of coal that is economically recoverable. This isn’t a tough and fast quantity, but relies upon upon the geological helpful resource, the market value, and the price of mining. The actual traits of the coal mining trade create distinctive challenges as a result of it endeavors to supply coal to the market at a competitive value, usually enhance miner safety and health, and meet environmental and group necessities. This chapter gives a short description of the characteristics of the coal commerce within the United States, presents an overview of coal extraction and processing strategies, and discusses the most important points related to coal mining and processing. A summary of present research actions supported by state and federal companies supplies the context for options for essential future analysis.
