Coal Transport
An efficient, economic transport system is a
key element in the viability of coal mining in
Australia and coal mining is a major contributor
to the viability of the state rail systems in
NSW and Queensland.
The oldest producing areas are located close
to the coast where domestic transport is well
established. However, as more remote deposits
are being discovered and worked, as production
volumes increase and as the manufacturing/production
chain speeds up, it is crucial that the transport
infrastructure is simultaneously developed and
expanded.
Rail
The
majority of coal is carried to its destination
by rail. In the major producing states, coal is
the single most valuable rail freight item and
where state rail systems did not originally extend
to coal fields, the installation of new track
and rolling stock has been funded by the mining
companies themselves.
Trains transporting coal are among the longest
in the world, with as many as 6 locomotives and
148 wagons amounting to a length of more than
2 kilometres. A train of that size can carry about
8,500 tonnes of coal.
An important innovation in Queensland at the beginning
of the 1980s was the construction of aluminium
wagons equipped with rotating couplings which,
enable the wagons to be emptied by being turned
upside down to reduce unloading time.
The main rail companies operating in Australia are QRNational and Pacific National who together service the States of Queensland, New South Wales and South Australia.
Conveyors
Many
of Australia's power stations have been built
close to the coal mines servicing them and use
overland conveyor systems to transport the coal
from the mine to the station. At the ports conveyors
are also used to carry coal from a stockpile to
offshore shiploading berths.
Road Transport
Road transport is used by a number of mines located
away from rail facilities but, generally, trucks
are used only for shorter hauls to the port or
rail loading facilities.
The Australian coal industry is conscious of the
impact of road transport on local communities
and actively seeks to reduce the impact by selecting,
where possible, the least inhabited routes and
by improving vehicle safety, noise and cleanliness.
