The classical maximum closure problem is of particular importance to the mining industry because it is the underlying formulation related to mine design and ...

This paper attempts to incorporate equipment selection/allocation into the optimization of open pit mine production scheduling. Equipment selection has been ...

The characterization of the spatial continuity of categorical variables, such as geological units, is a longstanding subject in geostatistics. Indicator cova...

This paper proposes a stochastic integer programming (SIP) formulation to address the optimization of long-term mine production schedules, whereby the supply...

The spatial continuity of lithology and ore grade is one of the key factor for proper mine planning. Traditional geostatistical methods are used for spatial ...

In the era of big data, data sets have been growing very large, and interest for algorithms and computation framework that handle such large scales is increa...

This paper proposes a heuristic approach based on network flow techniques to schedule the production in open-pit mines, while accounting for metal uncertaint...

Traditionally, mining engineers plan an open pit mine considering pre-stablished conditions of operation of the plant(s) derived from a previous plant optimi...

Cutoff grade specifies the available supply of metallic ore from an open pit mine for the multiple processing and refining streams of the corresponding minin...

Mining operations can be modelled as a supply chain from the sources of raw material (mines) through various processing streams to the final saleable product...

Preferential sampling of high grade zones is a common practice in the drilling campaigns of ore deposits. This may lead to a bias in the statistics derived f...
