Dragline Optimisation: US$30M Improvement in Just One Strip

Learn how eXcellerate achieved a reduction in dragline rehandle from 135% to 70% through strategic design and sequencing.

Overview

eXcellerate was engaged to enhance dragline productivity for a major mining client. Leveraging decades of experience in dragline operations, eXcellerate identified and executed strategies delivering a significant step-change in performance and a US $30M improvement in just one strip.

Key Actions Taken

To achieve this remarkable improvement, several strategic actions were implemented:

Optimised Blast Timing:

By carefully adjusting the blast timing, we were able to double the cast prime.

Geotechnical Constraints:

We tested and removed unnecessary geotechnical constraints, giving the dragline greater flexibility in positioning, which improved overall efficiency.

Dig Method:

Changing the dragline dig method reduced rehandle and increased the consistency of coal flow, streamlining operations.

Scheduling:

We restructured the drill and blast schedule to optimise dragline sequencing, ensuring the most effective use of spoil room.

The eXcellerate Way

At eXcellerate, we focus on building long-term capability, not just delivering technical solutions. By investing time in one-on-one coaching and leading group discussions, we empower our client teams to challenge the status quo and foster collaboration.

Our approach:

Sharing our deep, accumulated industry experience
Breaking down silos to foster a culture of collaboration
Instilling confidence in the team to challenge existing assumptions Enhancing the technical skills of the planning and operations teams
Encouraging innovative thinking by questioning assumptions previously accepted as facts
Bringing together industry talent and expertise to achieve informed and lasting outcomes

The Outcome

A substantial bottom line saving, and a valuable increase in the capability and confidence of both planning and operations teams. This step-change not on improved dragline productivity but also reinforced a culture of continuous improvement and innovation within the organisation.
