PROJECT DOWNTIME MINIMISED WITH THE HIGHEST LEVEL OF DUST SUPPRESSION
M2 TUNNEL UPGRADE
SYDNEY, NSW
SYDNEY, NSW
BACKGROUND
Transurban, a toll road operator, was undertaking a tunnel widening project at the Epping Section of the M2 to change the road from two lanes to three lanes.
During the project, boring into the tunnel wall was required, which led to the production of massive amounts of dust.
PROJECT OBJECTIVES
The road header bored away at the tunnel wall in order to create an extra lane.
Due to the amount of dust produced, this 10 month project would lead to decreased visibility in an already dark tunnel. Additionally, the dust could cause health and safety issues for workers and nearby residents.
The project objectives were as follows:
Improve visibility on worksite and for drivers
Reduce the amount of dust
Maintain project bottom line
CHALLENGES
The project faced the following challenges:
- Dust produced during the project made it difficult to maintain visibility on the worksite, posing risks to the workers and drivers in the tunnel.
- The dust also caused health and safety concerns for workers and nearby residents.
- The project was scheduled to be completed within ten months, and any project downtime could lead to significant losses.
SOLUTION
To address the challenges, BlastOne recommended using a mobile dust collector.
A mobile 20,000cfm Dust collector was able to follow the road header on night shifts, ensuring a high level of dust suppression, and then drive back to the compound 5 kilometers away – this was very important for the client.
RESULTS
The implementation of the mobile dust collector resulted in the following:
- Zero project downtime: The project was completed within the allocated timeline, with no significant disruptions caused by dust-related issues.
- Improved safety: The mobile dust collector effectively suppressed the dust, reducing health and safety concerns for workers and nearby residents.
- High level of dust suppression: The mobile dust collector ensured a high level of dust suppression, improving visibility for workers and drivers.
CONCLUSION
The final result was zero project downtime and the highest level of dust suppression. Contractors could work safely in the tunnel while road boring was being carried out.
The solution provided a high level of dust suppression, improved visibility for workers and drivers, and maintained the project bottom line by ensuring zero project downtime.

Experience the BENEFITS
VISIBILITY
Dust collection units are an important component for blasting site environmental and personnel safety. The removal of dust and other hazardous air particles protects the employees on site, while also preventing harmful contaminates from escaping into the atmosphere without relying on personal respiratory equipment alone.
HEALTH
A dust collector is used to provide ventilation inside containment structures to maintain operator visibility and maintain the encapsulated area under a negative pressure. It is also important to dilute the levels of hazardous substances within the contained area to levels below the minimum requred protection factor for personnel within, as well as respirator equipment limitations.
ENVIRONMENTAL
Many older coatings contain a high percentage of lead which when pulverized into powder by abrasive blasting can form a hazardous and toxic dust. Company legal obligations on project sites are now requiring that a full dust-tight containment structure encapsulates all blasting operations to minimize the danger to personnel and the environment.

FREQUENTLY ASKED QUESTIONS
How do dust collectors work?
Dust laden air travels down the ductwork and enters into the dirty air inlet plenum at the rear of the dust collector. Here the heavier particles drop out of the air stream. The air is then drawn through a large bank of high efficiency filter cartridges where the dust is deposited on the outside of the filter cartridges. Filtered air passes through to the clean air plenum and passes through the fan blower to the atmosphere. The cake of dust on the cartridges is dislodged continuously by an automatic reverse pulse jet.Dust drops into the hopper of the collector and is transferred by a screw conveyor to a conveniently located dust outlet for easy transfer to a receptacle for disposal.
Do dust collectors run on diesel or electric?
Some job sites are different to others. Contractors know that they can save a lot of money when the job site has power available. That is why BlastOne offers a bi-powered dust collector. Run it on plant power, generator power, or use the inbuilt diesel engine — it’s your job, your choice.What's more cost effective? Skid or trailer mounted?
The most cost effective option for a mobile dust collector is to mount it on a skid base. The dust collector can either be moved around using a large yard forklift or craned on and off a truck. This option is good for projects which have long durations and the unit isn’t required to move around onsite much at all. The skid has fork pockets, rigging mounts and extendable/collapsible legs to make transportation easy.What are options for mobility?
Yard Towable TrailerThe next step up in mobility — if you have a long project duration (2+ months), the yard towable trailer gives the ultimate site portability. While it needs to be loaded on a trailer to be delivered to the site, once onsite, it can be moved easily, as required. The ultra-heavy duty wheels & axels will last you many years of hard service.
Highway Towable Trailer
The ultimate mobility. Perfect for projects that are short in duration (under 2 months). The highway towable trailer means that the dust collection system and power/fan unit are all mounted on a highway certified trailer meaning that the unit can be moved anywhere at any time.
