cost models of theoretical mining operations

various models for surface mining operations, identifying important constraints and suitable objectives for an equipment selection model. A new Mixed Integer Linear Programming model is presented that makes use of a linear approximation of the cost function. This model allows for mixed-type fleets and selects the truck and loader types

Theoretical cost models for a broad range of sizes and types of surface and underground mines and mills. In addition to capital and operating cost summaries, most models provide listings of manpower, equipment and daily supply needs.

Abstract. This work adds the Activity-Based Costing Approach in mining operations with a product mix. After analyzing and collecting data from an aggregate mine located in Brazil, a cost model was built, and from that, a cost management and analysis methodology of a mine in operation is created.

Botín and Vergara [16] presented the cost management model for a sustainable economy and a permanent recovery of mining operational costs. Kusi-Sarpong et al. [17] analyzed mining industries ...

Mine cost estimation may be done at many levels. At first it may be a simple "back of the envelope" estimation using similar operations to benchmark against. Later it may be decided to use an existing mine that the company owns and factor and compare costs against them.

a few mining operations to increase margins throughout the boom-bust-boom cycle of 2008-2010. This paper seeks to demonstrate that robust modelling of operational cost and value drivers across the extended life of mining operation is a key requirement for maximising value, regardless of the economic cycle. Introduction

the mine site Problem: Cost forecasts are often based on theoretical OEM estimates of component life and repair costs without modifying for their real-world use. Solution: AMT holds both the theoretical OEM estimates as well as the real-world component cost and life numbers that are critical to developing realistic strategies, forecasts and ...

4 | KPMG Mining Operational Excellence Framework Retaining cost leadership Increase in cost of operation due to escalation in raw material cost (e.g., explosive cost, electric power, etc.). Certain costs of operations such as wages, utilities, construction and maintenance costs are quite sensitive to possible general price increases.
