1Challenge

An operating system was in place, but its data was not being turned into useful information for decisions. Management asked USC to build a closed-loop MOS for the long-hole mining process.

2Approach

  • Upgraded short-term planning for long hole, MCF and PCF areas across the upper and lower beats
  • Built a 'zero-based' capacity plan using unit cycle times for each major work activity
  • Revised supervisor routines to cut non-value-added work and trained the client's team to run the MOS
