Abstract

Estimating the costs of mining projects is among the most important and main stages in justifying the economic plan of a mine. Suboleski presented a model based on annual production capacity in underground mines and the size of the mine in order to estimate machinery and costs, which was published in the SME, Mining Engineering Handbook. The second edition of this model in the year 1992 was based on the financial conditions of that time and could be applied outside of Iran and especially in North America. The given relations of this model cannot be used to estimate the costs in Iran. In this Study, the relations are modified and updated to present an estimation suitable with the local conditions of Iran using official statistics and data and taking the special status of Iran into account. In order to do this, the percentage of each of the effective scopes of work in each of the relations with the influential coefficients were achieved, then the effect of the changes in currency value and the inflation status from the base year to the target year are considered in order to update each of the relations. Finally, a table of Suboleski’ s relations due to the ratio of 2. 39 to update the US dollar-time relationship and another table for the specific relations of Iran with regard to the adjustment coefficients of each sector were presented (for each separate section due to the specific modification of that section calculations are provided with). Using tables and daily Tonnage that mined, the users can get an estimation with at least 25% precision of operating cost and capital cost of the mine.
