Estimation of coal resources in Texas Gulf Coast, Ohio northern Appalachian, and Wyoming Powder River Basins: a comparison of statistical approaches | 1983 | Official estimates of United States coal resources published during the past 15 years vary from less than 1.5 to 3.5 trillion metric tons (1.7 to 3.9 trillion short tons). These differences imply that a high degree of uncertainty exists in resource assessment. |
