Australian Mining Output Hindered By Rail & Port Bottlenecks
Thursday, May 17th, 2007I am sure that you have seen the news about mining companies having to scale back coal production due to infrastructure problems.
Rio Tinto’s Coal & Allied Division announced a 20 percent cut in coal production due to bottlenecks in rail infrastructure and Newcastle Port. As a result, 250 miners will lose their jobs this month.
Other mining companies in the NSW Hunter Valley have also had to scale back production due to these same issues. The Austar mine last month announced that it would cut 79 jobs because it could not get enough port access.
Mining companies have tried to reduce the impact of the port problems by re-introducing a quota system for port access.
A consortium led by BHP Billiton has recently been granted approval to build a third coal export terminal. However, this will not open until 2009.
There has been a lot of people jumping up and down about this issue with the port infrastructure.
However, as an engineer, I understand that infrastructure and equipment has operating capacities. When designing systems to handle coal throughput, you only design the system for the required throughput.
Why?
We know that extra capacity or throughput costs more money. Therefore, predictions are made about requirements and the system is designed to meet those requirements. Any bigger, and it costs more - sometimes a lot more.
Recently, I was in charge of a coal handling system upgrade, and we were faced with the same issue. Many people wanted to know why we didn’t install larger conveyors, etc.
Another issue lies in accuracy of predicting coal output requirements. Some people were saying that the mining boom was going to continue; others were predicting an end.
Lastly, there is the issue of handling peaks in capacity. Sydney’s hospitality industry faced this issue during the 2000 Olympics. What happened after the Games finished? There were a whole lot of vacant motel rooms.
If you have sufficient capacity to handle any possible requirement, most of the time there will be idle capacity. Again, this costs money.
Sometimes, it is hard to make decisions about required capacity, and we are seeing the results of reaching capacity limits with our infrastructure due to the mining boom - just like we did with motels during the Sydney Olympics.
