Re: Metso/Dawson - Cable Belt Overland - Running?
Hi Lawrence,
Hope you and your family have had a very Merry Christmas and a Happy New Year.
I have only had verbal confirmation that the Moura Cablebelt has been 'Popping' and causing disruption and housekeeping issues. The maintenance staff have mentioned that the conveyor is in my words, not their expletives, substandard and inferior. I have not personally seen the belt but expect to view the system when I visit in the very near future.
The engineering staff are less than impressed and would like it replaced with a more reliable conventional conveyor which they have people who at least know how it works. Apparently, ground movement could be causing issues, but I will not know until I have eyeballed the system.
I will keep you informed of ongoings.
By the way, the Westfarmers Curragh North Mine Overland is roughly adjacent to the Lake Lindsay Cable belt while the Dawson Mine is 200 kilometers south east of Curragh. I have not seen and have to visit and view the Curragh overland conveyors in the near future. ■
Dawson
Dear Mr Nordell,
We are currently installing 4x of the 3rd generation CBM carcass scanning systems at Dawson (yes, the ones that can see individual cords and display a 3-D profile in real-time) and the cable belts are still not working properly - still jumping.
It is quite likely that at least one will be replaced with a conventional belt (if site personnel get their way)

Overland Cable Belt Replacement @ Lake Lindsey??
Thanks to Stephen & Tecmate:
Stephen:
Can you provide some details on the new scanner and belt cover gauge measurement equipment? Please correspond through my email below.
There is a large pent-up need. I hope you are able to allow clients to do their own scanning. Do you post accuracies, and examples of resulting reports??
Have you approached Curragh? Would you like a contact, support and a visit to Curragh?

Dawson:
I hear the Dawson system is producing something, but, not to specification, its very, very late; very, very unreliable, with many operating difficulties – cables dislodging, adding many sheaves to control cables and spillage, unusual vibrations, belt cleaning(?), and other critical issues. It’s a work in progress.
This leads to the question about the Cable Belt viability. Will Anglo indorse it to other clients? How long will it take before Metso is successful in meeting the intended scope?
Metso and Anglo had a profit sharing deal. Wonder what profits they are going to share?
-----------------
Lake Lindsey:
Will Anglo Coal reissue Lake Lindsey for bid with a conventional trough conveyor or, will they put themselves in double jeopardy? Maybe this is the replacement to come?
-------------------------------------------------------------------------------
Tecmate:
We keep our ear to the ground. I would like to be the bug on the wall of the Anglo executive office now. I will be in Australia within the next 30 days. Maybe, we can do the tour of Curragh and Dawson. We are hoping to do some testing at Curragh now that the system has been performing well, with close to a year of production.
I was a little put out when Parsons-Brinkeroff offered and chauffeured our competitor a tour of Curragh before Dawson went into commissioning. Interesting that he was claiming, to some, as the designer of Dawson in collaboration with Metso. He may be having second thoughts. ■
Cable Belts
I will email you some information on both technologies. To answer your question, yes data acquisition and analysis is done on-site in real time, so site has access to the scan data at any time. The comparative analysis module will be out in a month or so which will automatically compare the last two scans with the current and flag changes based on either % change or rate of change (site selectable). Longitudinal resolution is +/- 0.5 mm and analysis slice can be set as fine as 1 mm step at any speed up to 10 m/s, but I doubt if many people will use this setting.
We have not yet approached Curragh formally as yet so a contact and a site visit would be appreciated if at all possible.
I do not belive Anglo will continue with Cable belts but the Dawson exercise will continue until they get something that produces some tonnage - currently they are at about 20% capacity. I have to be somewhat politic about my views as Metso act as our agent in Sweden for Aitik / LKAB but I do agree with your view re: cable belts and their limited viability

Cable Belt @ Dawson & Lake Lindsey
Steve,
Another month and a half have pasted with no word on Dawson and Lake Lindsey progress. Any news?
We will be requesting to do testing on Curragh in the new future, to update our knowledge of the change in power over the last year of production and on the performance of some special features added to the belt technology. I anticipate this will take place in the month of March, with permission of Curragh.
I can introduce you to the client if you have not already done so. If we obtain the go-ahead, this might be a good time to connect.
There is more to this story I will share when we meet. ■
Re: Metso/Dawson - Cable Belt Overland - Running?
Hi All,
The Moura 'Cable Belt'. From my collegue who has seen and had a talk with the engineering staff at Moura says the uptime of the belt is poor and downtime is horrendous. He states the spillage and tonnage carried is still only at a fraction of that required and the maintenance is very high.
I am hoping to visit the site in the next fortnight so will keep you posted. I thought the quality of the technology would have improved since the 1990s. ■
Curragh
Hi Larry,
No ggod news from Dawson I'm afraid. We are back onsite in a couple of weeks to check on the scanning systems, but the cable belt is still grossly underperforming.
No, I have not been to Curragh yet - floods got in the way the last time I was in the vicinity. Be haapy to meet up when you are out here
Best regards ■
Re: Metso/Dawson - Cable Belt Overland - Running?
Steven,
Have you ever scanned a steel cord belt that does not lay flat?
I am working on an existing overland that is curling into a pipe conveyor. No, I am not the designer.
The client wants to obtain a report on the cable and cover status.
Can youo hint at the cost via email? I do not wish to say more, in public, at the moment. The project is in the USA. ■

Can you email me your coordinates in CQ to the address below?

METSO/DAWSON - Cable Belt Overland - Running?
Have Metso sorted out their problems with the 10 and 17 km Cable Belt overlands at the Anglo American Dawson Mine in Queensland?
Last word I heard, just before Christmas, was the belt was jumping the cables or visa versa. It appears to have happened on both belts. ■
