Earthworks and Controlled Blasting

Controlled blasting is a safe and precise method for loosening hard rock which is used alongside conventional construction methods such as excavators and scrapers.


The Toowoomba Second Range Crossing is being built using a cut to fill process, whereby earth is ‘cut’ or excavated and moved to then ‘fill’ a new area or embankment which is formed by adding materials from the cut.

To excavate the cuts, a variety of methods may be used depending on the ground material and include excavators, scrapers and blasting.

For hard or high-strength rock, controlled blasting may be required once all other excavation methods have been exhausted. The scale of the blasting depends on the daily progress of excavation earthworks and is subject to changing weather and site conditions.

The project team will notify directly affected residents and motorists about controlled blasting activities in advance.

For more information on the process, see our earthworks and controlled blasting factsheet. Or for more information about transportation of cut and fill material to site visit our haulage page.
