Mining Optimization: What does it mean? | Modular Mining …
Increased truck and shovel productivity enables mines to hit production targets. When it comes to fleet management, "optimization means ensuring that trucks arrive at shovels just in time to be loaded," says Neil Ferreira, Modular Mining's Associate Director of Product Strategy. "After it's dumped, a truck will automatically be sent ...

Optimizing the open pit-to-underground mining transition
Conclusions and future work. The methodology developed in this paper provides a robust framework for solving a linear-integer program representing an open-pit-to-underground transition model involving scenarios that contain 50,000 variables and over 1.5 million constraints. An ad-hoc branch-and-bound scheme fixes the variables that …

Optimizing short-term production schedules in surface mining …
Abstract. Short-term production scheduling is the operational basis for mine production over time spans of days, weeks and months. Short-term schedules concentrate on making long-term mine plans operationally feasible and ensuring a steady flow of product for both meeting gross production targets and blending ore.

A Genetic Algorithm-Based Approach for Optimizing Short-term Production
Optimizing the short-term production schedules independently at each mine fails to capture the benefit of generating schedules for all the mines collaboratively resulting in sub-optimal schedules. In short-term production scheduling, there are fewer blocks and thus fewer binary decision variables as compared to the long-term …
