Optimizing Open Pit Block Scheduling with Exposed Ore Reserve
A crucial problem in the mining industry is to determine the optimal sequence of extraction of blocks, in which the mine has been structured for exploitation. Typically a mine can be constituted by several thousands or millions of blocks. The sequencing models for this structure are very complex giving rise to very large combinatorial linear models. Operational mine plans are usually produced o...
متن کاملScheduling in iron ore open-pit mining
During the last few years, most production-based businesses have been under enormous pressure to improve their top-line growth and bottom-line savings. As a result, many companies are turning to systems and technologies that can help optimise their supply chain activities. In this paper, we discuss a real-world application of scheduling in the mining industry. This is a highly constrained probl...
متن کاملAggregation heuristic for the open-pit block scheduling problem
In order to establish a production plan, an open-pit mine is partitioned into a three-dimensional array of blocks. The order in which blocks are extracted and processed has a dramatic impact on the economic value of the exploitation. Since realistic models have millions of blocks and constraints, the combinatorial optimization problem of finding the extraction sequence that maximizes the profit...
متن کاملA genetic algorithm approach for open-pit mine production scheduling
In an Open-Pit Production Scheduling (OPPS) problem, the goal is to determine the mining sequence of an orebody as a block model. In this article, linear programing formulation is used to aim this goal. OPPS problem is known as an NP-hard problem, so an exact mathematical model cannot be applied to solve in the real state. Genetic Algorithm (GA) is a well-known member of evolutionary algorithms...
متن کاملOpen-Pit Block-Sequencing Formulations: A Tutorial
A classical problem in the mining industry for open-pit mines involves scheduling the production of notional three-dimensional production blocks, each containing a predetermined amount of ore and waste. That is, given operational resource constraints on extraction and processing, we seek a net present value-maximizing schedule of when, if ever, to extract each block in a deposit. We present a v...
