Abstract

In this U.S. Bureau of Mines report, mine and mill cost models are presented to make quick estimates of the cost to develop mineral deposits in the desert region of the Southwest United States. Regression analysis was used to generate capital and operating cost equations for each model in the form Y = AX', where Y is the cost estimated and X is the assumed daily capacity

Coal Terminology: Resource Reserve

Conversely, the successful development of new technology such as Underground Coal Gasification could increase the size of coal reserves. Additionally, uncertainties in the underlying resource estimates will also change the reserves – increasing as more coal is discovered, or decreasing as incompletely-mapped coal deposits turn out to be smaller than anticipated.
