A Block Aggregation Method for Short-Term Planning of Open Pit Mining with Multiple Processing Destinations

نویسندگان

چکیده

Clustering approaches are widely used to group similar objects and facilitate problem analysis decision-making in many fields. During short-term planning of open-pit mines, clustering aims aggregate blocks based on their attributes (e.g., geochemical grades, rock types, geometallurgical parameters) while honoring various constraints: i.e., cluster shapes, size, alignment with mining direction, destination, type homogeneity. This approach helps reduce the computational cost optimizing mine plans. Previous studies have presented ways perform without constraints specific mining. paper presents a novel block heuristic capable considering set aggregation requirements constraints. Constraints can relate adjacent blocks, achieving higher destination homogeneities, controlled consistency clusters mineable shapes types’ The proposed algorithm’s application two different datasets demonstrates its efficiency capability generating reasonable meeting predefined

Resilient Decision Making in Open Pit Short-term Production Planning in Presence of Geologic Uncertainty

Short-term production plans are the basis for operational mine production schedules. They concentrate on making long-term mine plans operationally feasible. Furthermore, some variables such as ore grade and tonnage govern mine production systems and cause uncertainty in the supply of raw materials to the mills. Due to the quality variation of material, short-term production optimization is an u...

A Chance Constrained Integer Programming Model for Open Pit Long-Term Production Planning

The mine production planning defines a sequence of block extraction to obtain the highest NPV under a number of constraints. Mathematical programming has become a widespread approach to optimize production planning, for open pit mines since the 1960s. However, the previous and existing models are found to be limited in their ability to explicitly incorporate the ore grade uncertainty into the p...

Aggregation 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...

An Uncertainty-based Transition from Open Pit to Underground Mining

There are some large scale orebodies that extend from surface to the extreme depths of the ground. Such orebodies should be extracted by a combination of surface and underground mining methods. Economically, it is highly important to know the limit of upper and lower mining activities. This concern leads the mine designers to the transition problem, which is one of the most complicated problems...
