ABSTRACT
Determination of mining capital cost always is a challenging issue for mining engineer. Underestimating the capital cost may postpone the construction and production phases. In addition, overestimating may decrease value of the project. Currently available capital cost estimation models cannot predict mining capital cost in a reliable range of error. Therefore, in this paper, a model based on regression tree method is developed to estimate the mining capital cost. According to the obtained results, the capability of presented model to estimate the mining capital cost in a wide range of mining capacity is significant.
