Tunnels and Ventilation Shafts
Abergeldie is a leading specialist in mining, micro-tunnelling and tunnelling construction across Australia and New Zealand. Specialists in the water, wastewater and stormwater sectors using trenchless technology, constructing deep pipelines in a wide range of geotechnical conditions using a range of techniques for ground support and stabilisation and in safe mining infrastructure provision.
Abergeldie owns and operates a large road header, both AVN and EPBM pipe-jacking rigs for trenchless construction of tunnels, and four of the world’s largest blind bore shaft drilling rigs.
Abergeldie has a comprehensive inventory of underground construction equipment, including jumbo drills, boggers/scoops and road headers.

The Abergeldie Tunnel Boring Machine (TBM) plant fleet caters for a broad range of geological conditions from soft ground earth pressure balance machines (EPBMs) to mixed ground slurry machines capable of tunnelling in running sand through to hard rock. Our fleet of TBMs allows tunnels with internal diameters ranging from 400mm-3000mm to be constructed.
The pipe jacking procedure enables tunnels to be drilled and hydrostatically lined with low risk of surface ground movement and minimal disruption to the surrounding community. For construction of underground pipelines, cable tunnels, ducts and culverts and for tunnelling under waterways, under roads or through difficult ground conditions, pipe jacking provides a safe, efficient, non-disruptive solution.
Our ability to provide a faster, safer and more reliable way of boring large diameter shafts for access, ventilation and foundations has been well-proven in the successful completion of blind bored ventilation shafts for clients like BHP Billiton, North Goonyella Coal, Springvale Coal and Centennial Coal.
Our capabilities also include drill and blast, directional, drilling, pipe ramming, moling, horizontal auger boring, mine grouting and assessment, and design and installation of steel and concrete head frames. Remediation and stabilisation services are also available.
Safety Legislation and Guidelines
Abergeldie is the proud holder of a mining Health, Environment and Safety Champion Award. Our strict adherence to safety legislation and guidelines for the protection of your mineworkers and our mining engineers recognises and addresses logistics within a restricted space, breathable air and toxic gas levels, groundwater drainage and mine support, stabilisation and reinforcement. We are fully certified to carry out all large-scale mining engineering works throughout Australia.
Abergeldie also has extensive experience in shaft and tunnelling remediation works, projects include the Blackall Range Tunnel Remediation. Scope of works included scaling and bogging to remove loose rock from the tunnel’s surfaces and the installation of GPR rock bolts.
