content of the feed coal from 26.93% to
about 4.71% in the stabilised coal.
According to Robin Eves, President
and CEO of CCTI, these results,
combined with the company’s previous
testing results, will enable the company
to confidently say the moisture level of
the stabilised coal can be reduced to
levels desired by the end customer.
“Simply put, we have completely
validated the dehydration process
section of the Pristine M Technology,”
said Eves. “The corresponding increase
in heating value of the coal was almost
2000 Btu/lb, from 8767 Btu/lb in the
feed coal to 10744 Btu/lb in the
stabilised coal. The results also showed
no degradation of the coal during the
process. These are phenomenal results
this early in the commissioning process.”
Putting Terex Trucks to
the test in Siberia
Six Terex Trucks TR 100 rigid haulers
are in operation at SUEK’s Apatsky
opencast coal mine in the most
northerly point of Zabaykalye Territory
in the Kalarsk region, working against
temperatures as low as -50˚C in the
winter to keep Russia warm. The
haulers are working 24/7 at the mine,
carrying out up to 100 runs a day.
“The TR100s work round the clock
and have proved to be a good choice to
suit our operating conditions perfectly,”
commented Oleg Likhodumov, Deputy
Director of the Apatsky mine. “They are
reliable and easy to maintain. For
stripping areas and coal mining, we
also operate 38 t Terex Trucks
articulated haulers, the TA400s.”
The cabin is equipped with safety
guards for protection onsite and
features air conditioning and heating
systems to ensure a comfortable and
productive operation.
Operator Maxim Shoizhalsanov, has
driven Terex Trucks TR100s for over
three years. “The big advantage of this
machine is its hydraulic brakes,” he
said. “They ensure dependable
slowdown on steep slopes and are good
on the ascents. A retarder in the gearbox
is useful because it allows good
slowdown on the descents.”
Equipment, technology
and services
Taking on surface drilling
challenges
Atlas Copco has launched
SmartROC D60, a surface drill rig that
can be used in a wide variety of surface
drilling applications. It is a versatile
down-the-hole (DTH) rig and is
designed for drilling 110 – 178 mm
holes.
The SmartROC D60’s hole
navigation system (HNS) and auto
positioning system ensure that the rig
will locate the exact position of each
hole and then accurately collar and drill
them to precisely the required depth
and inclination. This gives a better
fragmentation and improves both the
loadability and crushability.
In addition, the standard feed,
carrying 5 m tubes, features built-in
sensors in the rod handling cylinders
and carousel motor, enabling more
reliable rod handling and eliminating
the need for inductive sensors. The rig
also has Auto Rod Handling as a
standard feature to automatically add
and then extract the rods when the
desired depth is reached.
In addition, the SmartROC D60 has
low fuel consumption, which is
achieved through intelligent control of
the compressor load and engine RPM,
resulting in an estimated fuel saving of
