For small capacity mines, 40% of the capital cost of the large capacity mine is used based on trends seen in the capital cost calculation for refining. The variable portion of the cost calculation is based on the open pit mining models published by the USGS, which take into account several factors that affect capital expenditures (Camm, 1991).
remains to maximize the profit by extracting the material at lowest possible cost over the -life mine (Askari-Nasab et al., 2007). Since truck and shovel operations account for approximately 60% of total operating costs in open-pit mines, optimal use of these equipment is essential for the profitability of the mine.
Two main types of mines Open pit mining Roughly ten times lower in cost per ton compared to under ground mining Slope stability decide waste/ore ratio With low grades a high production rate is needed Big equipment for high volume production Under ground mining Under ground mines commonly have lower production rate Increased cost to infrastructure and ground support

Cost-efficient Transport for Open-pit Mines. An innovative technological approach to skip haulage could optimize costs and energy efficiency in hard rock mines. Open-pit metal mines are often shaped like an inverted cone, with the ore and overburden being drilled and blasted, then loaded and transported by shovel-and-truck systems.
23-08-2019· Developed an ANN model for estimating mining capital cost for open-pit mining projects with high accuracy. • Compared with the other machine learning algorithms include Random Forest, Support Vector Machine, and Classification and Regression tree. • Analyzed the influence factors on mining capital cost for estimating mining capital cost. •
In this paper, costs in open pit mines are categorized into four groups: (1) capital costs, (2) operating costs, (3) general and administrative (G&A) costs, and (4) fixed costs. …
