Mining has many applications for Lean Six Sigma! There’s a great return on investment when it’s applied to projects that can increase utilization of expensive equipment and improve work practices of highly skilled people. Here’s some project outcomes:
- Improving conveyor belt maintenance and use to have belt life greater than 2000 hours
- Improved maintenance of large haul truck tires increased hours of use, thus deferring tire replacement by 3 months
- Reducing soft tissue injuries of underground mining staff by active use of a fitness coach and exercise to strengthen muscles
- Reducing inventory by 50% by tracking forecast accuracy on a line item basis, increasing the forecast frequency, and focusing on no stockouts for standard items. Customers were able to reduce inventory on hand where before improvement they carried one month’s inventory to ensure available stock
Keys to the success of these projects were selecting a key performance measure that tied to a specific process that could be studied. I hope this gives you an idea of how you can apply Lean Six Sigma at your mining company!
