We know Mining
Let us demonstrate with this case study.
Client
- Underground mine located in Northern Canada
- Daily ore production of approx. 4000 tonnes
- Shaft hoist capacity at 8000 tonnes per day
Issues
- Sand-fill infrastructure unreliable
- Unsatisfactory cost and safety performance, in 3rd quartile range
- Productivity
Key Methodology
- Effective Questioning Conversations
- Workforce contribution of work sequence planning an integral feature of the weekly plan
Resolution
- Draft 7+21 Day Planning Schedule available with plenty of time for workforce input, amendment and commitment
- Work sequence and bottleneck issues identified in advance and managed
- Sand fill line preventative maintenance changed from ‘calendar time’ to ‘volume of sand’ throughput
Mine output increased 92% to 7680 tonnes per day
Outcomes over 18 months
- Key bottleneck areas in mining production and maintenance resolved
- Just-in-time delivery of mining supplies from collar house to work areas
- Mine output increased 92% to 7680 tonnes per day
- Actual costs reduced to 1st quartile
- Safety performance significantly improved – 1st quartile
