Circular 891 Coal Resource Classification System

Measured and indicated resources contain coal classed as reserve base, and inferred resources contain coal classed as inferred reserve base. Some measured, indicated, and inferred resources are subeconomic because they are too thin to mine or are buried too deeply to be mined by current extraction techniques; furthermore, parts of the reserve

Coal Resource Classification System of the U.S. Geological

However, where a coal bed at single data point cannot be correlated with beds at other data points, or where there is only one data point, resources can be calculated for that coal bed using the single data point as the center of circles defining measured, indicated, and inferred.

How much coal is left U.S. Energy Information

Jun 04, 2020 The amount of coal that exists in the United States is difficult to estimate because it is buried underground. In 1975, the U.S. Geological Survey (USGS) published the most comprehensive national assessment of U.S. coal resources, which indicated that as of January 1, 1974, coal resources in the United States totaled 4 trillion short tons.

Coal National Geographic Society

Coal is an important part of the world energy budget. It is relatively inexpensive to locate and extract, and can be found all over the world. Unlike many renewable resources (such as solar or wind), coal production is not dependent on the weather. It is a baseload fuel, meaning it can be produced 24 hours a day, 7 days a week, 365 days a year.
