Swarm –Based Truck-Shovel Dispatching System in Open Pit Mine Operations
The dispatch of trucks and shovel has always been an important component in the success of open pit mine operations. Dispatch systems have evolved from manual to today automatic with almost no human intervention. Although dispatching systems available today are “pseudo real time” and efficient, the optimal dispatching is realized over subsets of the fleet when dealing with large fleets. This ap...
متن کاملDetermination 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...
متن کاملDevelopment of a goal programming model for optimization of truck allocation in open pit mines
Truck and shovel operations comprise approximately 60% of the total operating costs in open pit mines. In order to increase productivity and reduce the cost of mining operations, it is essential to manage the equipment used with high efficiency. In this work, the chance-constrained goal programing (CCGP) model presented by Michalakopoulos and Panagiotou is developed to determine an optimal truc...

متن کاملThe effect of price changes on optimum cut-off grade of different open-pit mines
Maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. When this is the case, the price of the product has a critical effect on optimum value of cut-off grade. This paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (NPV) of operation. In order to visualize this ...
