MT WBM (BMT), a subsidiary of engineering
consultancy BMT Group, has been awarded a
contract to design a major new conveyor system for
the Loy Yang coal mine in Victoria, Australia. The
opencast mine supplies coal to the Loy Yang Aand B power
plants. The new systemwill transport overburden to a new
internal dump in a worked-out section of the mine. Historically,
overburden spoil was transported to an external dump up to
10 km away fromwhere the material was being excavated.
BMT will be responsible for the overall design on the
conveyor system, providing the detailed design for civil,
structural and mechanical elements, as well as liaising with
AGL Energy’s in-house team, which is delivering the
electrical design. The new conveyor system will have the
capacity to transport up to 8500 tph of material on 2 m wide
belts running at 5.3 m/sec. The new downhill conveyor will
be approximately 1.34 km long, dropping 131 m to the mine
floor, using three 1000 kW variable-frequency drives to
generate power and introduce it back into the grid. The new
conveyers have been designed as a modular system with
inherent flexibility to allow for unstable ground conditions
and will deliver a power saving of around 5 MW over the
existing system through 1 MW of regeneration and 4 MW of
reduction in demand.
As part of the project, the very large travelling stacker has
to be moved to the floor of the mine, crossing the 500 MW
Basslink cable, which connects the electricity grids of Victoria
and Tasmania, during an outage planned for March 2017.

Cargotec subsidiary, Siwertell, will supply a shipunloader to
the Mai-Liao coal-fired power plant in Taiwan, adding to the
Terex Trucks has appointed Babcock
International as its official distributor in
southern Africa.
