background
Kestrel Mine
  • 20 year old mine.
  • Highest profit returning business for Rio Tinto Coal Australia.
  • We have a young, energetic and mature workforce.
  • Tony Lennox had a focus on “good reputation” as a measure of success and good reputation is built on principles and actions.
  • Lean Thinking is based on good principles and actions.
  • Farthing West has been assisting us to implement Lean at Kestrel.
  • Three areas of influence:
    • People Behaviour - involvement in problem solving (ideas and actions)
    • Process Users - Standardise and improve processes (end users)
    • Equipment Processes and maintenance.
  • Its all about the people Developing Worker Problem Solvers.

Longwall ( Kestrel Longwall)

Kestrel - One of the top producing mines in Australia

And we do it with old equipment

Safety Comparisons

Kestrel – the best safety record in Australia.

And we are working hard to make it safer

Kestrel – Pillar cycle times improving.

In spite of more support, greater cross grades (now 1:11),

Typically weaker roof (less than 10 mpa) and high water intakes

panel advance tools
3 Key Documents
  • There are 3 documents that make up the suite of tools for the panel advance :
    • The Overview
    • Detail Cards
    • Check Lists
  • Note it is the intent to incorporate the trigger for issuing all documents onto the panel sequence plan on the Lean Story Board.

When management (ERZ controller/supervisor, coordinator, superintendent etc) checks on progress the focus is on learning and improving. If progress is lagging what are the root cause issues?

KME is targeting more improvement.

A 10 day pillar cycles.

time to first coal
Comments
  • Time to First Coal is averaging in excess of 4 hours per shift after allowing for Panel Advances, mobilisation and Maintenance days.
  • Typical best times are about 1 hour 20 mins

meetings pass training
Comments
  • In the order of 2.2 days per 28 days are lost for meetings pass and training - the morning meeting accounting for a significant portion of this time

road works
Comments
  • 1.3 to 2.1 days per 28 days are lost with road cleaning. This time probably understates the problem.

cutting time
Cutting time

Presently

Only 6 days cutting every 28 days

cutting time 34 hour per week to 50 hours
Multiple small steps
  • Getting the crew away on time
  • Having the transports from pit bottom to the panels pre started
  • Controlling meeting times
  • Using between shifts and cribs to clean roads etc
  • Concentrating on horizon control to reduce the need to clean roads
  • Having tradesmen stay at the face to prove that the machine is producing correctly
  • Train outbye workers to assist in manning the miner during one of the two crib breaks
  • Staying at the face to cut till the end of the shift
  • Commence planning for overlapping shifts to improve maintenance window utilisation
Cutting time 34 hour per week to 50 hours

Pillar Cycle Modelling more hours

Focusing of roster issues – 30% improvement
