Show April 2002 NMA 155 Energy releases estimates on retrievable coal resources in U.S. According to statistics compiled by the National Mining there are still approximately four trillion tons of retrievable coal resources located in the United States. The total coal resources in the n, effective energy resource unmatched anywhere in the world. Coal that can be extracted using existing mining technology is referred to as the "demonstrated reserve base. Americas domestic coal reserve base registers in the neigh- borhood of 4!X) billion tons. The amount of coal that can be recovered economically differs from area to area within the United States, points out the NMA data. Recovery of the natural res source depends upon such as geology method of mining; environmental or other restrictions, etc. The percentage is referred to as "recoverable coal reserves. Using a recovery rate of 60 percent, the nations existing coal reserves are estimated at approximately 295 billion tons. fee-tor- child in the United States. At present rates of recovery and use, experts forecast that US. coal reserves will last more than 250 years.
