through the use of a heuristic model<br />

involving reclamation cost requirements,<br />

linear programming can contribute<br />

worthwhile information to the mine planner.<br />

Caccetta and Keley (1987) declared there are<br />

two basic requirements of mine site<br />

rehabilitation: (i) that the site is safe, stable<br />

and non-eroding at the end of the life of the<br />

mine; and (ii) pollutants such as acidproducing<br />

waste must been buried and been<br />

capped with impermeable material. They<br />

developed a mathematical formulation of the<br />

mined land surface reshaping problem (the<br />

first requirement).<br />

King (1998) shows how rehabilitation and<br />

closure costs of mines impacts the<br />

production rate and cut-off grade strategy for<br />

a mining operation. Rashidinejad et al<br />

(2008a) developed a model for optimum cutoff<br />

grades that not only relies on economical<br />

aspects but also minimizes adverse<br />

environmental impact in the form of acid<br />

mine drainage elimination or mitigation<br />

against the approach of postponing the<br />

restoration/reclamation activities at the end<br />

of the project’s life. Rashidinejad et al<br />

(2008b) developed another useful<br />

methodology that maximizes the profitability<br />

of a mining project and minimizes its<br />

adverse environmental impacts<br />

simultaneously. The acid generating<br />

potential of waste materials and tailings in<br />

each alteration zone can be estimated by<br />

laboratory and in-situ tests. They developed<br />

a modified cut-off grade model with the<br />

concept of elimination or reduction of the<br />

AMD in the original place. Four coefficients<br />

that discriminate between acid generating<br />

and non- acid generating waste material and<br />

tailings incorporated into the Lane’s model<br />

to ensure optimality of cut-off grades.<br />

Gholamnejad (2009) inserted mine<br />

rehabilitation cost into the optimization<br />

process and a new mathematical model<br />

developed based on Lane’s method. Results<br />

of the application of this method show that<br />

considering rehabilitation cost can decrease<br />

the cut-off grade. Dogan et al (2009) studied<br />

the effects of different block size on reserve,<br />

waste amount and distributions of chemical<br />

component such as %CaO, %MgO in quarry<br />

located at Darica, Istanbul. Scenarios with<br />

different block dimensions created by<br />

integrated mining software namely Surpac<br />

6.1 and were compared. Effects of different<br />

blocks on reserve, waste amount, chemical<br />

distribution, and estimation of quality of<br />

cement raw material were determined.<br />

Gholamnejad and Mojahedfar (2010)<br />

developed a mathematical model for<br />

determination of the largest pit with the nonnegative<br />

net profit in the open pit mines.<br />

They declared this strategy can increase the<br />

life of mine which is in accordance to the<br />

sustainable development principals. Craynon<br />

and Karmis (2011) declared that By utilizing<br />

geographic information system (GIS) tools<br />

to evaluate available data on environmental<br />

and social resources, the regulatory barriers<br />

which prevent operations from incorporating<br />

ecological and other sustainable<br />

development concerns into coal mine<br />

sustainability performance were identified.<br />

By analysis of the on-the-ground issues<br />

related to sustainability, the key parameters<br />

to be incorporated into an optimized coal<br />

mine design in Appalachia are discussed<br />

along with possible changes to the<br />

regulatory framework that would enhance<br />

incorporation of sustainability into coal mine<br />

design. Ataeepour et al (2012) developed a<br />

mathematical model for determination of<br />

UPL with simultaneous maximization of<br />

profit and ore content. They introduce a new<br />

characteristic of deposit that named<br />

“potential of extension” that is a guide for<br />

designer for UPL selection on base of<br />

resource efficiency and profitability.<br />

2 UPL DETERMINATION ON BASE<br />

OF SUSTAINABLE DEVELOPMENT<br />

ASPECTS<br />

2.1 General description<br />

As above-mentioned, there general<br />

method for UPL determination is on base of<br />

profit aspect and there is no consideration on<br />

sustainable development aspects. We try to<br />

develop a method for captioned subject.<br />
