Finding Added Value at Newmont through Large-Scale Mining Sequence, Cutoff Grade and Process Optimization using Mixed Integer Linear Programming
The articule explains general concepts of dumps design and gives a study case appling new computers tools in order to give answer to the planning of waste dumps associated with mining plan at low cost and according of the environment norms.
The purpose of this report is optimization by looking the best net Present Value for a given open pit mine project. This is relevant to the mining business, especially in the mining sequence with cutoff grade policy. To do that, it is used a software to calculate phases and mining sequence and another for cutoff grade policy.
Uno de los grandes desafíos que la planificación minera ha debido enfrentar durante los últimos años, es el creciente incumplimiento de los planes mineros, tanto en la adherencia a la estrategia de producción como metas anuales comprometidas.
Los sistemas de carguío y transporte son ampliamente usados hoy en día en las operaciones mineras por su alta flexiblidad para la extracción del material. Los sistemas de transporte y carguío tienen menos restricciones, pero esto no significa que sean económicos. La eficiencia y el costo efectivo de estos sistemas son sensibles a varios factores.
Long Term Mine Planning requires a thorough understanding of the activities and resources needed to meet the company ´s predefined target production rates. The imprtance of defining a very near plan to the reality will ensure a significant saving of resources for the company.
