FORMATION OF McCONNELL DOWELL MASTERMYNE JOINT VENTURE;
COLLABORATION AND INNOVATION FOR THE UNDERGROUND COAL SECTOR

2. MORE THAN JUST A
MINING CONTRACTOR
McConnell Dowell & Mastermyne have formed a highly
capable team to enable the delivery of the underground
infrastructure including the Cut & Cover, Drift Driveage and
Ancillary Works.

4. McConnell Dowell and Mastermyne have formed
a highly capable team of delivering underground
infrastructure to the mining industry. This Joint
Venture has been ‘Made-to-Mine’.
The McConnell Dowell and Mastermyne
Joint Venture (MDMJV) unites the
respective strengths of two of Australia’s
strongest and most capable underground
contractors from the civil infrastructure
and coal mining sectors, forming arguably
the most robust delivery team for “mine-
to-market” projects.
The McConnell Dowell Mastermyne Joint
Venture provides resource owners and
developers a total mine solution. Feasibility
through to market delivery, we have the
depth and capacity to offer all disciplines.
MDMJV will provide the necessary step
to change the underground coal sector
for the safe and efficient delivery of mine
access drives using rapid advance, full
face tunnelling technology. This would in
turn make resource access more efficient,
cheaper, and safer.
Our international and domestic
workforces continue to show steady
growth, with more than 10 000 staff
combined and all with one culture
and goal – to ensure we remain at the
forefront.
Our people represent the best and
brightest in their fields. We’re proud of
the passion and success of our teams
in striving to be the industry leaders,
and it shows in our individual results
– as a Joint Venture we are even more
formidable.
Our fundamental philosophy of finding
creative solutions to engineering and
construction challenges for clients
has never changed, with ongoing
relationships with our clients being one
of our key strategies. We each have
a track record of building long-term
relationships with both national and
international clients, which is testament
to our innovative and client-focused
capability.
We believe that our Joint Venture is
capable of providing superior advance
rates and a safe work system within
a fully compliant framework. This
methodology will significantly change
the face of Australian coal mines. It will
enable a lower cost per unit of coal from
underground mines, and through the use
of innovation will reduce the number of
people required to work underground.

PRECAST
The McConnell Dowell and Mastermyne Joint Venture (MDMJV)
unites the respective strengths of two of Australia’s strongest and
most capable underground contractors from the civil infrastructure
and coal mining sectors, forming arguably the most robust delivery
team for “mine-to-market” projects.
MDMJV Project Team were recognised for their
safety record and management record during the
course of the project.
AngloAmerican approached McConnell Dowell Mastermyne (MDMJV)
early 2015 to complete the TBM Drift works for Grosvenor Coal
Mine.
The work scope included the following:
• Installation of Drift Floor within Conveyor (CV) and Men
and Materials (MM) Drifts
• Excavation and Shotcrete of Man Refuges
• Installation and Commissioning of Blast Doors for CV and
MM Drifts
• Installation of LED Lighting within CV and MM Drifts
• Completion of Surface Portal Works at CV and MM
Portals
• Concrete Ramp Pours at Pit Bottom from Installed Floor
Segments to Mine Pits
• TBM Drift Fit-out works
• Surface TBM Portal works including concrete ramp
construction, surface sump
MDMJV as a team brought the following value as a whole to
the Grosvenor Coal Mine project:
SCHEDULE OPTIMISATION
Started with 43 week programme and completed core work
in 28 weeks
PROCUREMENT OPTIMISATION
Smarter solutions proposed by the team saved Anglo
significant costs
QUALITY OUTCOMES
With systems and process the quality of work produced,
with supporting documentation, was of the highest order.
COLLABORATION
Having combined civil and mining skills, within the Anglo
office, made for a dynamic and positive culture of a high
performing team.
MDMJV worked closely with Anglo American to obtain all
approvals and to ensure all management plans were implemented
without delaying construction programme.

6. 3. MCCONNELL DOWELL
TUNNEL & UNDERGROUND
Our tunnelling capability is unrivalled. More than 30
years’ experience, the delivery of 140 km of tunnels,
and over 4 million tonnes of materials moved: this is
the McConnell Dowell difference.

PROJECT SUMMARY:
The Bogong Power Development
Project, awarded to McConnell Dowell
by AGL Southern Hydro in September
2006, consists of a network of tunnels
and shafts and the construction of a
new underground hydro electric power
station near the Victorian ski fields at
Falls Creek. The power station forms
part of AGL Southern Hydro’s strategic
energy framework for the supply of
green peak demand power. It harnesses
the Rocky Valley and Pretty Valley
branches of the East Kiewa River and
existing water resources released from
the Mackay Creek Power Station to
generate 140MW of renewable power.
The construction of the underground
power station included the excavation
of the station box, a top down
excavation utilising secant pile walls,
rock anchors and excavation in rock to
25 m below the ground. The massive
box was created from which 30,000
cubic metres of material was excavated,
and the power station structure
required over 10,000 cubic metres of
concrete.
Pivotal to the success of the power
station is the co-ordination of the
crucial mechanical equipment including
turbines, generators, draft tubes and
inlet valves and scroll casings. These
massive individual pieces require
installation as the power station is
constructed from the depths of the
excavation.
CHALLENGES
Being constructed in an alpine national
park meant the project was highly
scrutinised by AGL Southern Hydro
and the EPA – and the results were
exceptional. To quote AGL Southern
Hydro’s Project Manager John Arnold:
“The statutory authorities cannot speak
highly enough about the work done by
McConnell Dowell. The work they are
doing is being used as a benchmark for
future projects.”

This project required the excavation
of a 6 m x 2.6 m decline, on a site
that consisted of conglomerate and
sandstone ranging up to 140 MPa in
hardness.
McConnell Dowell employed a unique
blast and drill option to meet the
challenge.
A completely pneumatic system
avoided the procurement risks
presented by the flame-proofed
electrical equipment and permanent
gas monitoring systems traditionally
used within a decline.
The roof support crawler rig, custom
designed and built as part of the
project, was the first of its kind in the
world.
The project was awarded to McConnell
Dowell by Centennial Coal and was
completed within 18 months.

7. Mastermyne commenced its first
development contract 14 years ago
at the Kestrel North Mine in Central
Queensland. Since that initial project,
we have driven more than 200 km
of roadways on 12 sites across
Queensland and New South Wales.
