The Rock Reinforcement center in Feistritz/Drau, Austria
The Atlas Copco Swellex plant in Canada
Atlas Copco Rock Reinforcement
Ongoing development of faster, safer and more exotic tunnelling techniques places a constant pressure
on manufacturers to provide more efﬁcient rock support solutions which will help the shortening of cycle
time. As ground conditions get more and more demanding, emphasis is placed on ﬂexible and intelligent
support systems in which rock and soil reinforcement is expected to contribute to the productivity and
safety of the operation. The trend has been to provide rock support and reinforcement systems that are
easy to install, assure efﬁciency and provide safety.
For the last 25 years, Atlas Copco has been offering the SwellexTM concept as a unique, safe and reliable
system of rock support. As the market leader in underground rock excavation technology, Atlas Copco
has also been developing safer and more efﬁcient rock reinforcement products such as the Manganese
line rock bolts, which are manufactured from a special type of steel. Another development is the Swellex
Premium line of rock bolts, for use where high yield load and stiffness are expected from the reinforcement system.
When Atlas Copco bought MAI in 2001, the rock reinforcement center moved to Feistritz/Drau, Austria.
This acquisition made it possible to introduce a whole new range of products for Atlas Copco customers,
the MAI SDATM anchors, which are now being developed for mechanized installation by both surface and
underground drill rigs, creating fresh applications in rock and soil reinforcement.
Atlas Copco’s Rock Reinforcement Center in Austria brings together the skills necessary for the development of superior rock reinforcement products to serve the tunnelling, mining and construction industries
worldwide. The combined product portfolio includes Swellex rock bolts and MAI SDA anchors with all
necessary accessories.
The strategy to act as “The professional supplier of speciﬁc and complete solutions in rock and soil reinforcement” has paid off, and the effort to invent and commit ourselves to more productive solutions is
stronger than ever.

Quality assurance means safety
Quality assurance – for safer
reinforcement
Safety in a mine is not something Atlas Copco,
takes lightly. It’s a major issue for those who own
and those who work there. A minor fault in a reinforcement bolt may prove fatal. That’s why
Atlas Copco rock bolts are rigorously tested to ensure the best possible quality and reliability. In fact
our Quality assurance system is the most comprehensive on the rock reinforcement market today.
ISO - Management systems
that work harder
ISO standards represent the best management
systems for quality and environmental issues. It’s
therefore not surprising that Atlas Copco is ISO
9001 certiﬁed to systematically control overall
quality. The company is also ISO 14001 certiﬁed to minimise the environmental impact of the
company. These are applied at every Atlas Copco
manufacturing plant as well as every distribution
and customer centre. They basically form the basis
of the company’s Quality Assurance program.
Quality control starts at the
suppliers...
ISO certiﬁcation is the prerequisite for every
Atlas Copco supplier. Whether it’s rods for MAI
self drilling anchors or steel proﬁles for Swellex,
suppliers have to follow our speciﬁed tolerances.
To ensure their quality, we test every batch for
deviations and register the results.
...and ends at the clients
To conﬁrm that ﬁnished bolts can withstand the
working pressures stipulated, we carry out destructive tests on samples of Swellex bolts and MAI
self-drilling anchors. And if this is not enough, every bolt is stamped with its own number. So should
a problem arise, the cause can be efﬁciently traced
back and action can be taken promptly to rectify it.
In accordance with ISO9001, Atlas Copco has
developed comprehensive instruction and training
material to enable end-users to install bolts and
anchors correctly and safely.
4
Quality assurance means safety
MAI SDA self-drilling anchors
There are two important quality parameters for a
MAI self-drilling anchor. Firstly, that anchors can
withstand the stipulated working pressure and,
secondly, that couplings and bits can be easily
threaded.
Ultimate load tests are carried out on 1 in 200 of
the manufactured anchors. A special test bench
pulls these anchors until they break and the results
are monitored. Should an anchor fall short of the
given tolerances, production is stopped and the
fault is rectiﬁed.
Atlas Copco MAI also offers a hot dip galvanized
MAI self-drilling anchor. This galvanised layer has
to be the right thickness for the couplings and bits
to be threaded on properly.
Again, a sample of anchors is removed from the
production line during each shift and the thickness
of the galvanisation is tested and registered.
Swellex rock bolts
This expandable rock bolt is more complex to
manufacture than a MAI SDA. The steel proﬁle is
pressed into shape and a bushing is welded on the
open end-piece. As pressurised water is used to
install a Swellex bolt in the hole, leakages are not
wanted. That’s why each and every bolt is tested
for leakage as part of the production process. This
unique operation is augmented by destructive
expansion tests where 1 bolt in 200 is pressurised
to the limit to ensure that the batch can withstand a
minimum a working pressure of 300 bar.
In effect, one sample bolt is removed at the beginning of each shift and one when a new batch of
steel proﬁles is used. This means that 1% of all
bolts are sacriﬁced in the name of quality assurance.
We, at Atlas Copco, believe that assuring quality
throughout the complete supply and distribution
chains is the best way of ensuring the highest level
of safety for our customers.
5
MAI SDA anchors versus Swellex bolts
The Atlas Copco MAI SDA is a unique bolting
solution for unstable ground conditions such as
sand, gravel, silt, and clays, and in soft to medium
fractured rock formations.
For projects facing such ground conditions, MAI
SDA self-drilling anchors should be considered as
the main productivity solution.
Atlas Copco Swellex rock bolts, which are
quickly and safely installed in rock not tending to
collapse, gives immediate support, speeding up
operations and boosting revenues. Over the past
two decades, the Swellex rock bolting solution has
become world famous as the simplest, fastest and
most reliable rock reinforcement technology available.
MAI SDA installation
The MAI SDA solution is designed for optimized
installation, tailored to the project’s needs. By
drilling a hole in collapsing soil or loose rock, with
a sacriﬁcial drill bit and a hollow rod, and after the
drilling operation injecting grout into the hollow
rod and surrounding cavity, makes it a top productivity solution.
MAI SDA manual installation
Swellex installation
The Swellex bolt is a folded steel tube, which is
inserted into a pre-drilled hole in the rock. Water
is blasted into the tube at high pressure, blowing
out the fold and expanding the tube into the exact
shape of the hole, adapting to every irregularity.
Bolt installation takes less than 30 seconds, and
provides full and immediate support along the
entire hole length, in ground conditions ranging
from the hardest rock to clay even non-cohesive
material.

Applications
steel reinforcement to resist the design load.
The application circle below displays the three
most important areas and industries where the
MAI SDA is best utilized
Slope stabilization
Is used to stabilise mostly unstable rock/soil formations which are normally benched prior to the
installation of the "soil nails". The unconsolidated
or weathered ground conditions favour the technique of Self Drilling Hollow Core Anchors (SDA)
for the fast and simple method of installation compared to the traditional methods of cased boreholes
and inserting of a suitable tendon.
Foundations with micropiles
MAI SDA micro piles can be deﬁned as small
diameter replacements, drilled piles, composed of
injected grout with the MAI SDA anchor rod as
The MAI SDA micro piles can be installed in sites
with limited headroom, restricted access capability
with light drilling equipment which have low noise
and vibration and require minimal site preparation.
MAI SDA can be installed successfully into most
ground conditions including rock and is suitable
for tension and compression loads. The big advantage is the combined drilling and grouting making
high piling outputs possible.
Tunnelling
MAI SDA anchors are the most economical
solution for the reinforcement of the tunnel circumference and advance roof support for tunnel
excavation in overburden and soft factured rock
conditions.

MAI SDA self-drilling anchors
Sacriﬁcial drill bits
The sacriﬁcial drill bit is the most crucial part
of the anchoring system, and is responsible for
the productivity of the installation. Atlas Copco
MAI maintains a large range of drill bits to suit
the changing demands of geology encountered on
different projects. In order to improve on performance and cost efﬁciency, data is collected from
projects around the world, and incorporated into
the design with the aim to improve penetration
rate and bit quality, and to reduce manufacturing
costs.
The selection of drill bits
A successful installation of the self-drilling anchor
system (SDA) depends on the selection of the
most suitable drill bit. Compared to conventional
drill bit types offered globally for maximum standing performance for rock or soil, the criteria for
SDA drill bits are deﬁned by consideration of the
following factors:
High quality for a limited service life
Installed MAI SDA length
Geology
Geometry
High quality for a limited service life
Geology
The unique MAI Anchor system was developed
over the years for the sole purpose of the drill bit
to penetrate fractured and weathered rock and
unconsolidated soil formations. Constantly varying conditions, from clay to gravel and boulders,
as well as sand and rock, require a multi-functional
bit design that provides:
Optimum cutting ability in mixed ground
conditions
Adaptable ﬂushing and grouting performance
Maximum penetration speed
Geometry
Project design for external skin friction demands a
selection of various drill bit diameters. In order to
maintain the functionality of the system, the following range of diameters should be selected for
the different anchor dimensions.

MAI SDA R38
76 mm, 90 mm
MAI SDA R51
100 mm, 115 mm
MAI SDA T76

Since the nature of the drill bit is sacriﬁcial, the
maximum stand up time is that required to install
one anchor.
MAI SDA installed length
Depending on the SDA applications, standard
drilling depths would be in the range of:
Tunneling (SDA): 4-10 m
Soil and Rock Nailing (SRN): 8-20 m (30 m)
Micro Injection Piling (MIP): 10-20 m
Temporary Support Anchors (TSA): 15-30 m

MAI SDA self-drilling anchors
Hollow anchor rods
The anchor rod features a hollow bore for ﬂushing, or simultaneous drilling and grouting, and has
a left-hand rope thread for connection to standard
drill tooling.
It is manufactured from API standard heavy walling steel tubing, cold rolled to form a standard ISO
rope thread proﬁle. The rolling process reﬁnes the
grain structure of the steel, increasing the yield
strength, and producing a durable drill rod suitable for a range of applications. The standard rope
thread of the anchor rod produces an excellent
bond between the rod and grout, as well as enabling connection to all Atlas Copco Boomer face
drilling rigs and Atlas Copco Roc surface drill rigs,
and use with a wide range of drill steel accessories.

Hollow anchor rods
The anchor rod is produced in 12 m lengths and
then cut to size depending on customer requirements. Standard delivery lengths are 1 m, 2 m, 3
m, 4 m and 6 m. Recommended maximum rod
lengths depend on diameter and can be up to 6 m.
Additional lengths up to 12 m are available on
request.
Extension couplings
The coupling features a patented design that
enables direct end-to-end energy transmission
between each bar, reducing losses and ensuring
maximum percussive energy at the drill bit.
To enable the correct seating of each bar within the
coupler, all bars are chamfered with precision to
enable the bar ends to have contact.

Bearing plates
The bearing plates are formed steel plates with a
centre hole, allowing articulation of seven degrees
in all directions.
All functional parts are constantly tested, in line
with the Atlas Copco rigorous quality assurance
policy.
Bearing plates
Hexagonal nuts
The hexagonal nut is manufactured with chamfered edges on both ends from high precision steel,
and tempered to meet any stringent demands of the
anchor speciﬁcations and the daily operations of
underground works.
All nuts exceed the ultimate strength of the bar by
20%.

Galvanized anchors
Corrosion is a very complex process, and corrosion rates are very hard to predict accurately. However, predictive methods can be helpful to evaluate
the need for corrosion protected rock bolts. For
this reason Atlas Copco has developed a hot dip
galvanizing corrosion protection. The full range
of SDA bars with couplings and nuts are available
with this corrosion protection.

4. Once grout has
hardened, the
anchor is perfectly
installed.
Semi-mechanized installation
Improved quality of grouting
The anchoring or bolting industry has a demand
for increasing the efﬁciency and quality of the
installation of bolts. In addition increased safety by
minimizing work in unprotected areas are becoming more important to contractors when installing
bolts in difﬁcult rock/soil conditions.
Better ﬁlling of borehole annulus due to in-situ
mixing process
Consistent load transfer over the whole bolt
length between soil/rock and bolt
Improvement of corrosion protection providing
longer service life
A change from the conventional post grouting
method to a semi-mechanized installation method
using an IRIA (Integrated Rotary Injection Adapter) method provides an adaptable installation process, which offers an improved solution and as such
added value to the Customer:
SDA installation becomes one work cycle performed only by the drill feed
No additional work cycle for post grouting
Reduced operation cost for additional equipment
(working platforms etc.)
Better adjustment of the installation process in
respect with the changing geology
Flexible selection and adjustment of ﬂush media
as needed (water, air or grout)
14
The option to introduce high speed stabilization
with SDA versus cased borehole drilling solutions
No separate drilling equipment needed,
same crew
No subcontractors and no investments in capital
equipment
Providing technology to introduce high speed curing grout formulas
Back pressures during grouting can be absorbed
by drill feed and boomer, thus enabling higher
grout pressures, thus allowing lower W/C factors
reducing the curing time, providing earlier load
bearing of SDA resulting in a reduced excava
tion cycle time.

Centralizer
A centralizer is available for specialist applications. For general use the centralizer is not required as it snags during rotation and interferes
with grout circulation in the borehole. The use of
a centralizer does not guarantee comprehensive
grout cover along the length of the bar as it's is impossible to control the grout within the borehole.
Coupling boxes
Centralizer
Manufactured from thick-wall steel which is
machined and case hardened. Coupling boxes are
used at high wear locations, typically just below
the hammer drive. A locking torque is normally
applied to the coupling box at the permanent joint,
to avoid release when additional anchor bars are
added.
All the coupling boxes are supplied with a bridge
to act as a centre stop.
When a step down (reducer) drive arrangement is
used i.e. R38 shank to drive to install R32 anchor
bar, a locking torque should be applied at the R38
end to prevent the R32 bar climbing into the R38
chamber.
Step up drive arrangements are not recommended
as the additional torque overloads the smaller
drive.
Coupling boxes
Shanks
Rotary percussion is the preferred method of installation. Either hydraulic or air hammer is suitable. To transfer the rotation and percussion from
the hammer to the bar's system there is a need for
the special tool named shank adapter. Atlas Copco
is providing a full range of different shank adapters for different hammers.

Grout coupling
After using standard ﬂushing media - water or air,
grouting has to be done. For connecting the grouting hose from the pump with the anchor bar, the
grout coupling is used. The grout coupling will be
removed and reused after the grouting process is
done.
Grout coupling
MAI SDA mortar
The MAI anchor mortar is mostly used for grouting of anchor bore holes or for consolidation
grouting of fractured rock formation and loose
unconsolidated ground. Depending on the work
environment the MAI anchor mortar is available as
standard or sulphate-resistant type cement.
Processing
MAI anchor mortar is mixed with clean water; approximately 5.0 l/bag are needed. For processing,
standard mortar mixing pumps, especially the MAI
pump m400 NT are suitable.
Storage
The MAI anchor mortar is delivered in bags of
25 kg each. The bags should be kept in dry conditions, a max. shelf life of 6 months can be expected.
