Minemax releases new simultaneous Optimization of Pit and Waste Dump Scheduling software

Supplier News

The new Minemax Scheduler 6.1 with Simultaneous Pit and Detailed Waste Dump Schedule Optimization has been released, and is designed to jointly optimise detailed waste scheduling together with a mine schedule.


This new functionality has been developed in response to requests from users, who sought a detailed waste dump schedule together with the mine schedule. With the addition of simultaneous pit and waste dump schedule optimization, Minemax Scheduler can now calculate schedules that are more accurate and practical, and still optimise a mine’s net present value. 


Many mine schedules assume a truck cycle time to the centroid of the waste dump. Trucking requirements will actually vary depending on where the dump material goes in the waste. Therefore, with larger waste dumps in particular, a centroid approach will have a significant degree of inaccuracy. A common approach is to look at the ore/waste extraction in isolation to the dump schedule, which can be time consuming and possibly non-optimal. 


With Minemax Scheduler 6.1, detailed placement of waste onto the waste dump and the associated trucking requirements are considered, giving an accurate and optimal mine schedule. With this process, there is less manual tweaking of schedules, better utilisation of resources and greater confidence that the schedule achieved is both correct and optimal.
