Stochastic optimization of long-term block cave scheduling with hang-up and grade uncertainty
The current trend of deeper and lower-grade deposits makes open pit mining less profitable. Mass mining alternatives have to be developed if mining at a si...
référence BibTeXStochastic orebody modelling and stochastic long-term production scheduling for an iron ore deposit
For over a decade, stochastic optimization has emerged as a framework that is capable of generating a life-of-mine production schedule that increases ne...
référence BibTeXSimultaneous stochastic optimization of production scheduling at Twin Creeks mining complex, Nevada
Twin Creeks is a gold mining complex part of Newmont's Nevada Operations. The mining complex is comprised of two open pits, Mega and Vista, external ore sour...
