Total operating cost 12 1.09st. UNDERGROUND MINE MODELS. Each underground mining model includes the cost of development, daily production, and mine plant construc tion and operation. Using equation 4 or 5, daily mine capacity of ore can be calculated for an underground evaluation.
was developed to estimate capital and operating costs associated with various mining methods. This technique, developed under a Bureau contract by STRAAM Engineers, Inc., was completed in 1975, then updated in 1983. During the course of the update, it was noted that few provisions were made for estimating the costs of small-scale mining
The estimated engineering-based cost function shows operating economies in the sand and gravel industry. Geological factors are found to be important determinants of operating costs. A continuous approximation of the step- supply functions for extraction of sand and gravel is used to determine the short-run extraction supply elasticity,
Engineering cost modelAn engineering-based analysis of capital and operating costs associated with an industrial operation. Grade-tonnage modelThe frequency distributions and relations of tonnage and ore grades of a group of well-explored deposits that belong to the mineral deposit type being modeled.
