Removal of Steel from Our Underground Ore Stream
Olympic Dam is an underground mine, meaning we have to constantly rehab areas of the mine that we have explored previously. This means installing cable bolts, split sets etc. as ground support. When we mine new areas that have previously be rehabilitated, we have the issue of this ground support steel entering our ore stream. This has the capability to damage conveyor belts, block feeders and bog our crusher.
When the ore enters our ore passes, it is fed through grizzlies to stop any large rocks or steel from entering. From the ore passes it is fed in to an underground rail system where steel has the ability to stop the trains by damaging the catenary. The ore is then fed directly from the trains to the crusher where steel has the ability to block crusher. The ore then travels through a range of feeders and conveyor belts as it moves towards the ore haulage system. There are a few mag belts underground and one on the surface directly after the feeders to remove as much of the steel from the conveyors.
Ideally removing the steel before it hits the crusher and conveyor system is the most logical solution.
Potential Questions to answer
- How can we reduce the amount of steel in our underground mining operation?
- How can we reduce the amount of steel getting through our grizzlies?
- How can we reduce the amount of steel travelling through our conveyor system?
