YALLOURN MINING

RTL entered into an Alliance Contract with Yallourn Energy (now Energy Australia) in 2001 to undertake the operation of the Yallourn Mine. In so doing RTL became the first and only contract miner in the Latrobe Valley power industry.

RTL’s mining system is based around the dozer push model and replaced an ageing fleet of bucket wheel dredgers. The attraction of the dozer push model over the bucket wheel dredger is far lower capital cost and much greater versatility.

Dozer Push Mining System

RTL’s dozer push mining system is based around a fleet of highly modified Caterpillar D11 Dozers pushing to high volume throughput Feeder Breakers which feed coal onto a face conveyor system.

The D11 Dozers are fitted with a 94 cubic metre coal blade believed to be the biggest such blade in the world. At 3.63m high the special purpose blade is capable of moving 70 tonnes of brown coal per push. The dozers are fitted with GPS guidance and on board survey capability which is downloaded from a central computer server.

RTL is currently working with Caterpillar on remote control capability for the dozer fleet.

The Feeder Breakers at Yallourn have been purpose built to a design developed in the Yallourn Mine and have been designed to deliver up to 3,000 tonnes per hour onto the conveyor belt system.

RTL TRANSPORT

RTL transport operates a fleet of modern well maintained prime movers, trailers and floats and is able to provide over dimensional and general transport services to local Gippsland and South Eastern Victoria.

In addition to over dimensional and general transport services RTL Transport operates a fleet of 550 hp prime movers and aluminium bodied B Double trailer combinations carting coal from Loy Yang to the Morwell Briquette factory.

PRINCES HIGHWAY EAST DUPLICATION (value $43M)

Description of Works

The Princes Highway East Duplication Project, Flynn to Rosedale, is a design and construct contract issued by VicRoads (contract #8594) with a contractual program of 108 weeks. The duplication comprises of the construction of separate two-lane carriageways to provide a four-lane divided highway, with the new alignment crossing the existing in four separate locations and crossing three waterways. The duplication will address road safety, improve road capacity, improve road geometry and provide continuity between overtaking lanes.

The Princes Highway East Duplication Project, Flynn to Rosedale, is part of a wider project for the duplication of Princes Highway between Traralgon and Sale. Funded by both the Federal and State Governments, contributing $140M and $35M respectively, the project will be delivered by VicRoads South Eastern Projects.

The current project team has a 50/50 male-to-female ratio in both the office and field, and comprises of members of diverse backgrounds and ages with an age range of mid-twenties to mid-seventies.

Major environmental challenges of the project consist of working adjacent to waterways containing the Dwarf Galaxias and potentially the Growling Grass Frog (both species listed as vulnerable under the EPBC Act 1999), working in areas containing endangered flora and indigenous artefacts on Gunaikurnai Land (over 1,000 artefacts identified at Flynn’s Creek). Major safety challenges are working adjacent to live, high-speed traffic (over 10,000 vehicle movements per day), plant/personnel/heavy vehicle interaction and working adjacent to overhead and underground services (such as the Regional Outfall Sewer).

Scope of Work

The project involves approximately 8.5km of duplication in total, comprising of:

  • A four-lane divided carriageway with a 15m wide median
  • Two new bridges over Flynns Creek, to the south of the existing carriageway
  • A new bridge at Blind Joes Creek, to the north of the existing carriageway
  • New culverts, including a major structure at Middle Creek
  • Provision of a replacement truck stop at the existing Flynns Creek bridge, for eastbound traffic
  • Wide median treatments at Flynns Creek Road, Wrights Lane and Cricket Street intersections
  • Strengthening of the existing bridge over Blind Joes Creek

Construction activities will include, but not be limited to the following:

  • Site establishment
  • Site clearing and vegetation removal
  • Earthworks
  • Roadworks
  • Drainage
  • Retaining walls
  • Bridgeworks
  • Roadside protection works
  • Transport and haulage
  • Landscaping
  • Street lighting
  • Rehabilitation and reinstatement

LONGFORD GAS CONDITIONING PLANT — SITE PREPARATION (value $28M)

Description of Works

In October 2013, RTL Mining and Earthworks were awarded a contract for the civil and infrastructure works for the new Exxon Mobil Gas Conditioning Plant at Longford. The contract was awarded by CB&I Constructors Pty Ltd who are the Engineering, Procurement and Construction (EPC) contractors charged by Esso to develop this new plant.

This $1 billion dollar Gas Conditioning Plant project will process gas associated with the largest domestic gas development on Australia’s eastern seaboard, the multi-billion dollar Kipper Tuna Turrum (KTT) Project. Gas from the KTT fields in Bass Strait varies in composition and the existing Longford facilities which have been operating for more than 40 years cannot process gas with the higher levels of CO2 and mercury, hence the need for the new conditioning plant.

Scope of Work

RTL commenced site works on 3rd December, 2013 on a greenfields site to the east of the existing gas plant. The initial program of works was 6 months in duration with scope of works consisting of:

  • 150,000 m³ of Earthworks
  • 43,000 m² of Plant Road Construction
  • 700 Lm of Insitu Concrete Trench Construction
  • 2,300 Lm of HDPE Fire Service Main
  • 15,000 m³ HDPE lined, Stormwater Pond
  • RCP Drainage
  • Cyclone Mesh Security Fencing
  • 10,000 m² Asphalting
  • Temporary Site Amenity Construction

Over the duration of the contract RTL’s scope has grown considerably to include general concrete and building construction works on the site. The proposed completion date for the civil and infrastructure contract is June 2015.

COMPLETED PROJECTS

RTL have completed a number of landmark projects. Some examples include:

MORWELL RIVER DIVERSION - Yallourn (value $120M)

Diversion of the Morwell River through the Yallourn Open Cut was undertaken under an Alliance style contract for Yallourn Energy (now Energy Australia). The project commenced in 2000 and was completed on time and under budget in 2005. The project involved the placement of 13 million cubic metres of engineered fill to create an elevated aqueduct some 3.5 km in length. The embankment accommodated 4 conveyor tunnels through which coal is transported from the Eastfied coal field to the power station. The project was a finalist in the 2006 Victorian Construction Achievement Awards.

RIVERS AND ROADS RELOCATION (value $100M)

In 2006 RTL were awarded an alliance style contract to divert the Morwell River and other tributaries around the Morwell Open Cut. The contract also included an 8km diversion of the Strzelecki Highway between Morwell and Yinnar including the construction of two new bridges.

The project involved some 10 million cubic metres of earthworks and were carried out under difficult conditions. The project was completed on time and under budget in January, 2010.

VICTORIAN DESALINATION PLANT (value $130M)

RTL were engaged as the principal Earthworks provider to the Thiess Degremont Joint Venture on the Victorian Desalination Plant project. RTL were the first contractor on site and maintained a presence on site until the plant gained final acceptance.

MORWELL MAIN DRAIN (value $7M)

RTL were awarded the contract for the remediation work for the Morwell Main Drain in 2012. The drain situated between the Princes Freeway and the Morwell Open Cut Mine developed significant safety concerns in 2011 resulting in the Freeway being closed for a many months until temporary works and control measures were implemented. The remediation works included lining 1,800m of drain with a combination of clay and impervious liners. The works were successfully completed before winter in 2013.
