US $30M improvement in one strip

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 docus 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.
