YANCOAL, CHPP DEMOLITION & SALVAGE STAGE 1 - STRATFORD & DURALIE, NSW
Stratford & Duralie, NSW
Feb 23 – March 23
In early 2023, Major Projects Group was contracted by Yancoal to carry out the demolition of the Train Load Out (TLO) facility and its associated infrastructure at Duralie Coal Mine, as well as the demolition of conveyors at Stratford Coal in New South Wales. This project involved work at two separate sites, namely Duralie Coal and Stratford Coal.
SCOPE OF WORK
The scope of work for this project involved the demolition of various surface Train Load Out (TLO) infrastructure and adjacent laydown areas at Duralie Coal and Stratford Coal. Specifically, at Duralie Coal, the demolition included the TLO Bin, Reject Conveyor, Rotary Breaker, Dump Hopper, Conveyor D1, Conveyor D2, Conveyor D3, and the Codam Processing Laydown Yard. At the Stratford Site, the works involved the demolition of the Coal Unloading System and Overland Conveyor, as well as Conveyor 18 and the Stacker.
TLO bin surrounded by protected assets, Including a Creek, Dirty Water Dam, Generator and Main Northern Line.
Continuous wall adjacent to Dump Hopper had to be unaffected by the demolition works.
Access roads to remain open for mine operation traffic and maintenance.
The demolition methodology employed by the site team involved the use of machine demolition methods, utilizing a 56t excavator equipped with a shear, which was employed in a methodical manner to systematically dismantle the conveyor structure along the conveyor line.
For the hopper, conveyor section, and TLO bin, an induced collapse technique was used, whereby a series of hit cuts were made to the structure to enable the excavator to pull it down and cause its failure, bringing it to the ground.
To remove the conveyor section next to the generator and substation, crane lifts were utilized. All generated debris resulting from the demolition works were carefully processed and sent to an authorized waste recycling facility for proper disposal..
The project was successfully completed ahead of schedule, with no incidents occurring during the works. Additionally, over 730 tons of scrap steel were processed and recycled, contributing to the project’s environmental sustainability goals.
