-35 to +35). To protect operators and maintenance staff from blizzards
and wind chill all conveyor gantries, stairwells and transfer
towers will be enclosed within insulated sandwich panels and
heated. Piping will be lagged, motors trace heated, special lubricants
used and concrete pours scheduled only during the annual
permafrost free period.
To add to the environmental challenges, what little surface water
exists remains frozen from November to March. Water for fire fighting
and coal processing will need to be stored, filtered and continuously
heated using coal-fired boilers to keep it circulating.
Electricity is another ongoing issue so back-up generators are
being incorporated into the designs.
The high fines content of the coal and its propensity to fracture
easily after handling results in dust generation potential. GWE’s dust
suppression solutions include orientating stockpiles to counter the
strong prevailing desert wind, the design of enclosed transfer towers
and conveyors, plus the inclusion of a dust-stilling chamber
above the dump hopper and loading out via truck bins.
Solving the Australian mining industry’s most demanding mechanical
and structural design challenges throughout the last
three decades has equipped GWE’s growing design teams with
an expansive understanding of the resource sector’s priorities.
Emerging technologies, new techniques and contemporary design
trends are assimilated to support the development and introduction
of new solutions to exacting challenges in the evolving
international mining industry.
