New Oakleigh Coal Mine Flood Repairs

Client

New Hope Coal

Location

Rosewood, South East Queensland

Project Scope and Challenges:

South East Queensland’s flooding event of 2011 had a significant impact on a wide range of infrastructure. JCB were immediately able to assist local government and existing clients to minimise losses and reconstruct vital infrastructure.

At the New Oakleigh Coal Mine, for example, we set to work de-silting the main dam and reconstructing damaged earthworks caused by flooding. The dam is situated in a wide water course below a dump area. JCB noted that the dam was not adequate to cater for the quantity of silt and spoil generated by the mine production and suggested to the client that it required a larger catchment to arrest silt before it flowed into the dam. A Swamp Dozer was brought in to expand the existing dam and direct excavated material to a Long Reach Excavator for removal.

Power lines were located over the top of this construction area which required risk assessments and Job Hazard Analysis to be drawn up to formulate a safe work process for the operators and equipment constructing the new catchment area.
