Considering Sustainable Development Concepts<br />

ABSTRACT Transportation costs have always been a significant part of large open pit<br />

mining capital and operating costs. It counts about 40 up to 60 percent of the total operating<br />

cost in open pit mining. The main goal of design a haulage system is an implementation of a<br />

plan that meets the required production requirements, operates at competitive cost, and<br />

complies with environmental regulations. Selecting the suitable haulage system can be<br />

considered as a MADM problem because the effective parameter are various, with different<br />

importance. In this study, the HPVS method that uses a DEA model to produce weights<br />

associated with each ranking place was applied to select the suitable haulage system<br />

considering sustainable development (SD) concept. This approach was tested in Sarcheshmeh<br />

copper mine of Iran. The result of this model shows that the combination of truck-shovel and<br />

in-pit crusher is as the most appropriate haulage system in Sarcheshmeh copper mine.<br />

1 INTRODUCTION<br />

One of the main proportions of operating<br />

cost of open pit mining is related to haulage<br />

capital and operating costs. Currently, truck<br />

with 360-ton capacity is running in some<br />

open pit and some researcher give indication<br />

to the employment of 420-ton capacity truck<br />

(Jacek, Zaplicki, 2009). The capital cost of<br />

truck with capacity around 300 ton reach<br />

above 2.5 million US $. Therefore,<br />

equipment selection is one of the most<br />

important aspects of open pit mine planning<br />

and design.<br />

The purpose of equipment selection is to<br />

select optimum size and number of<br />

equipment with minimum cost (Osanloo,<br />

2007).<br />

The selection of equipment for mining<br />

applications is not a well-defined process,<br />

because it involves the interaction of several<br />

subjective factors or criteria, decision on<br />

mine equipment selection in different mines<br />

are often complicated and may even embody<br />

contradictions.<br />

Different types of models have been<br />

developed to selecting the suitable mining<br />

equipment. Expert system as decision aid in<br />

surface mine equipment selection was<br />

applied by Bandopadhyay, et al.<br />

(Bandopadhyay et al 1987) and Denby,<br />

Schofield (Denby, Schofield 1990). Hrebar<br />

(Hrebar 1990), Sevim and Sharma used net<br />

present value analysis for selection of a<br />

dragline and surface transportation system<br />

(Sevim, Sharma 1991). Cebesoy used linear<br />

break-even model (Cebesoy 1997). Models<br />

for equipment selection and evaluation<br />

described by Celebi were aimed at selection<br />

of the equipment fleet based on minimizing<br />

the unit stripping cost and maximizing<br />

production (Celebi 1998). Hall et al.<br />

illustrated how reliability analysis can<br />

provide mine management with quantitative<br />

information of value for decision making<br />

about surface mining equipment (Hall et al.<br />
