The cost of unplanned downtime in mining services operations
Unplanned downtime in mining services operations is among the most expensive losses in the plant because a single failure, such as conveyor and crusher failures that stop the circuit, not just one asset, can stop the flow, not just one asset. The true cost pairs lost contribution margin with emergency labour and expedited parts, and is usually several multiples of the repair itself.
What drives downtime cost in mining services operations
- Conveyor and crusher failures that stop the circuit, not just one asset.
- Mobile fleet availability gaps that strand production.
- Shutdown scope growth and overrun that blow the budget and schedule.
- Parts and logistics delays that turn a short repair into a long outage.
