Five Komatsu 830E dump trucks delivered in mid-2011 to Yarrabee Coal in Queensland's Bowen Basin have been well received by the mine's operators.

According to general manager Ashley Souvan, the trucks which are mainly used for hauling overburden have shown dramatic productivity improvements compared with the previous trucks used in the application, and once some initial teething problems were sorted out.
"Since we had those issues sorted out, we've had no problems at all with the trucks," said Ashley.
"And the operators are very happy with them they absolutely love the trucks," he said.
The trucks are primarily loaded with another brand of shovel, and in some instances with Komatsu PC4000 shovels, hauling over distances of between 500-900 m. About Yarrabee Coal Mine.
The Yarrabee Coal Mine produces a low volatile, high energy pulverised coal injection (PCI) coal predominantly used in the steel industry.
ROM coal production for 2011 is forecast to be 2.7 Mt (million tonnes) with the longer term potential is to increase ROM production to over 3.8 Mtpa from 2013. Saleable coal production in 2011 is expected to be 2.6 Mt.
Yarrabee's mine plan consists of the extension of current mining areas combined with the progressive development of new areas as the older areas are exhausted, with measured resources being progressively converted to reserves as exploration activity advances and improves confidence in the resource model.
A number of drilling programs completed in recent years have added significantly to the resource base of the operation, with additional exploration drilling expected to further enhance the resource base in the project area.
The successful expansion of Yarrabee's operations depends on a strong safety culture, and it has a safety campaign focused on placing the mine in a favourable position compared with its industry peers.
Labour turnover is relatively low and ensures a safe and stable operating environment exists at the mine.
