ROCK REINFORCEMENT
software automatically compares both
measurements and presents in real time the
thickness of the applied shotcrete. This
information is shown in easy to understand
colours which directly gives an overview of the
targeted thickness and the under- or overspray
areas. Fast deployment and scan time help to
operate without breaks and the results can be
automatically generated for a concrete thickness
report.
Normet argues
that talented
operators at the
concrete
spraying
machine are
becoming
more and more
rare with the
result of huge differences
in the quality of the sprayed concrete. Due to this
fact, Normet developed the process automation
SmartSpray to minimise the operator effect and
increase the productivity of spraying. SmartSpray
is available in the three versions Lite, Pro and
ProPlus.
SmartSpray Lite allows the operator to control
only one spraying nozzle by using only one
joystick to perform basic spraying movements
instead of handling two or four joysticks. The
nozzle position is maintained to align the

this automation support
of SmartSpray Lite, the
operator achieves consistent
and high-quality spraying
results.
With SmartSpray Pro
automatic movements are
possible for regular
spraying. The spraying
nozzle moves from point-
to-point and the spraying
is automatic. The operator only needs to adjust
the distance to the surface and to move to the
next spraying segment. Large and smooth
surfaces in tunnels are the result of the
SmartSpray Pro.
SmartSpray ProPlus is designed to spray
automatically a before defined area. The system
automatically keeps the distance between the
spraying nozzle and the wall profile, maintains
the speed and achieves the demanded layer
thickness. SmartSpray ProPlus automatically
calculates the path for the nozzle
movement and sprays the concrete, turning
the sprayer operator from beginner to
seasoned master.
Sandvik MD bolt exceeds targets at
Dugald River
A safer, easier-to-install ground reinforcement
solution from Sandvik Mining & Rock
Technology has improved cycle times and helped
mining services provider Barminco exceed
ambitious development targets at MMG’s Dugald
River mine – one of the world’s largest known
zinc deposits. The Sandvik Mechanical Dynamic
(MD) bolt “has revolutionised ground support”
for Barminco at MMG’s Dugald River mine says
Sandvik. Dugald River will be one of the world’s
top 10 zinc mines at full production, and the
operation is ramping up faster than expected. It
achieved commercial production in May 2018 –
less than five months after the first concentrate
was produced as part of commissioning activities.
The mine produced more than 140,000 t of zinc in
concentrate in 2018. With a nameplate annual
capacity of 1.7 Mt, Dugald River is expected to
produce 170,000 t of zinc, plus silver and lead as
byproducts.
Barminco has been instrumental in developing
Dugald River since it won a 2012 contract to
advance two exploration declines and establish
production levels and other infrastructure. A
