Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining .
The coal industry in the United States—encompassing coal mining, processing, and transportation—is a relatively small but vitally important component of the nation''s provides nearly a quarter of all energy supplies in the United States, with most of this coal used to generate more than half of the nation''s electricity.

Recoverable reserves at producing mines are the amount of recoverable reserves that coal mining companies report to EIA for their coal mines that produced more than 25,000 short tons of coal in a year. EIA estimates these reserves at about 15 billion short tons of recoverable reserves, of which 62% is surface mineable coal.
In the working areas, the coal was loaded into mine cars and pulled by mules to the tipple or to the bottom of the shaft or incline for hoisting. Underground, the dip of the coal beds dictated the mining method to be used. In generally flatlying beds, variations of room and pillar mining .

Future coal mine expansions are highly uncertain as these expansions will face very serious geologic, economic, legal and transportation constraints. Importantly, the federal government owns essentially all of the coal in the western UnitedStates, and future coal mine expansions in western states will have to comply with a host of federal laws.

Abstract. Groundwater impacts are a common reason for opposition to longwall mining. Most impacts are due to subsidencerelated fracturing. Although upper aquifers are protected from drainage to the mine by a confining zone, water levels decline due to fracture dilation, and drawdown expands outward a few hundred meters.
Ø The goal of the planning and design of underground coal mining operations is a strategy for designing an integrated mineral exploitation system that will ensure that coal is extracted and prepared at a desired market specification, at a minimum unit cost, within acknowledged safety, health, social, legal and regulatory constraints. Ø
