Economic Feasibility of Semi-Underground Pumped Storage Hydro Power Plants in Open Pit Mines

A stochastic model for the daily coordination of pumped storage hydro plants and wind power plants

We propose a stochastic model for the daily operation scheduling of a generation system including pumped storage hydro plants and wind power plants, where the uncertainty is represented by the hourly wind power production. In order to assess the value of the stochastic modeling, we discuss two case studies: in the former the scenario tree is built so as to include both low and high wind power p...

Feasibility Study of Pumped Hydro Energy Storage for Ramea Wind-Diesel Hybrid Power System

Optimizing Long-Term Production Plans in Underground and Open-Pit Copper Mines

We present a methodology for long-term mine planning based on a general capacitated multicommodity network flow formulation. It considers underground and open-pit ore deposits sharing multiple downstream processing plants over a long horizon. The purpose of the model is to optimize several mines in an integrated fashion, but real size instances are hard to solve due to the combinatorial nature ...

Determination of the largest pit with the non-negative net profit in the open pit mines

The determination of the Ultimate Pit Limit (UPL) is the first step in the open pit mine planning process. In this stage that parts of the mineral deposit that are economic to mine are determined. There are several mathematical, heuristic and meta-heuristic algorithms to determine UPL. The optimization criterion in these algorithms is maximization of the total profit whilst satisfying...

An Approach to Locate an in Pit Crusher in Open Pit Mines

Transportation costs are a significant part of capital and operating costs of large open pit mines. Cost efficiency and high reliability of in pit crushing and conveying systems compared to conventional truck-shovel system makes it more appealing to be utilized in modern mining activities. In this paper the suitable location of an in pit crusher is investigated as a single hub location problem....
