FUTURE MINING AND UNDERGROUND AUTOMATION
Dynamic Tunnelling. “Veidekke is working on the
State highway 80 project in Bodø. There’s a
tunnel that's two times 2.5 km where we are
going to excavate about 500 000 m 3 of rock ”,
explained Jon-André Nilsen, Manager Surveying
Technic Underground, Veidekke. Nilsen continued
“The collaboration with Atlas Copco to develop
the Dynamic Tunnelling package went well. Atlas
Copco was responsive to our feedback and made
adjustments to the program. Today, the drill rig
operators make niches manually. They can turn
out way too big or way too small. Dynamic
tunnelling makes our drilling more precise. We
can make changes to drill plans directly on the
rig. We can move cuts or drill-holes. We are more
flexible at the tunnel face compared to making all

centre articulated, carrier-mounted ITH drill rigs.
The Sandvik 400 range is ideal for highly
accurate production drilling, as well as drilling
service holes and slot raises. It drills with ITH
hammers that are powered by on-board high-
pressure screw boosters. These can be used to
drill holes with a diameter of 89 to 216 mm. The
compressor control system controls the flow of
air to remain constant, not just unloading when
the pressure reaches maximum, which increases
safety interlocks and full-time monitoring and
data collection.
The updated drill module has fully modular
feed, carousel and centralizers, facilitating
maintenance and reducing service costs. At the
same time it also has a rebuildable/reconfigurable
system that allows for application changes at a
later date and gives the customer the ability to
change drill application by bolting on the new
components that are needed.
Radio remote tramming gives the operator the
possibility to tram and setup the unit without
being in the operator area, increasing safety and
allowing extremely precise setup, with excellent
visibility of the work area. The tramming can be
done on either diesel power or using the electric
power pack. The power pack is a multi-voltage
compliant system that gives customers freedom
to move the drill from one country to another. The
drill operates easily in different networks ranging
from 380 V-1,000 V and both 50 and 60 Hz.
Atlas Copco’s Dynamic Tunnelling package is
new automation software for face drilling rigs,
which offers improved accuracy of the advance
thanks to the fact that drill plans will always be
precise for the current section of a drift. With this
software the drill rig can create its own drill plans
directly at the face of the tunnel. Simply by
downloading the contours of the mine drifts to
the drill rig together with a drill rule file, the drill
rig can create drill plans tailored for the section it
is navigating within. This obviously means
improved production at a lower cost
