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 recoverable This 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

Coal is mined by both surface or 'opencut' (or opencast) and underground or 'deep' mining methods depending on the local geology of the deposit Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia's coal is produced from opencut mines
