The problem with Open Cut mining

If you experience more than 3 of the following issues you have substantial hidden capacity and unrealised profit in your mine which can be unlocked within 6 months.

  • You are concerned by the inability of operations to consistently meet their operational and financial targets
  • Despite focussed effort to improve efficiencies production output remains unpredictable, stuck below budget (or even decreasing)
  • You have moving bottlenecks in operations ( drilling, blasting, load & haul, crushing, plant)
  • Employees are frustrated by continuous priority changes and firefighting
  • The mine plan needs to be redone three days into the week
  • There is friction between planning and operations and operations don’t “own” the plan


Simulation shows that moving bottlenecks are inevitable when we try and maximise the efficiency of all the parts of the mine. Variability increases, and meeting financial targets become difficult. The more management tries to drive departmental efficiency, the worse the problem becomes. It becomes difficult to hold employees accountable, and trust and cooperation suffer. The managerial span of attention overloads and mine production and efficiency is below potential.

Insight/What we do:

The insight that we had was to realise that the root cause of the difficulties described is that mine departments operate in siloes. So rather than trying to optimise every department or every component of the mine, we should look at the whole mine and free up hidden capacity. We do this by making constraints visible, focusing effort here, and aligning the operational systems to maximise production flow.

The Flow Room solution

The productivity platform which unlocks hidden production capacity and unrealised profit in your mine within 6 months

  • SIgnificantly increased production, productivity and profitability
  • Stable operations that consistently meet and exceed targets
  • Improved safety
  • Greater transparency enabling decisions that satisfy short and long term pressures, improves cooperation and departmental alignment
  • Management time freed up to deal with strategic issues​
  • Engaged workers

We solve the "silo" problem by providing clients with a proven framework to examine the entire mine to identify the critical leverage points.  Focus on leverage points will deliver maximum value for the least effort in minimum time.

Traditional consultants focus on either cultural change (soft side) or operational improvement (hard side) – we believe that success requires simultaneous focus on both. And thus, we see ourselves as trusted advisors dealing with human behaviour and motivation, as well as processes and efficiencies.

We use the Flow Room to make this happen. The new way of operating will fit into your current system and will operate with minimal interference and changes while reducing your overall workload significantly.

"When we started this journey, our guys thought it would be impossible to achieve this but all doubt was removed when they shattered the mine's all time daily production record on Thursday, 6 September 2018. Four of our (five) sections are trending to achieve millionaire status shortly"

General Manager - Coal

"We managed to exceed all of our production targets. The Flow Room has substantially improved the communication and coordination between different departments. It enables our employees to see clearly how their area of responsibility fits into the overall performance and to hold each other accountable. We see problems developing in advance and deal with it in a spirit of calmness. I do not want to manage without it."
