increase production efficiency, and operator
ease. An adjustable indexing system allows the
operator to switch between drilling and bolting
functions, while maintaining bolt alignment with
drilled hole. The hydraulically operated bolt
holding/loading carousel makes for a more
efficient bolting cycle. The Independent feeds
allow the operator to manoeuvre the bolter with
ease, into difficult situations. Our patented
flexible bolt centralizer is a simple and cost-
effective design, it is made from a single casted
part, with shape-memory material properties
which allows the centralizer to flex out of the way
of the bolt driver.”
Split Set Mining Systems partners
with Minova
Ingersoll-Rand sold the Split Set ® group, now
almost 20 years ago, to three different
companies with jurisdiction in three different
parts of the world:
Australia and Asia, Europe Middle East and
Africa, and the Americas. These companies were
Phoenix Metalforms in Australia (for Australia
and Asia, now known as Split Set Mining
Systems or SSMS), Metal Service in France for
Europe, Middle East and Africa,
and International Rollforms for the Americas.
Minova (part of Orica) and SSMS have a long
history of working together in East and West
Coast but had never taken a step to formalise
this relationship. With DSI finalising its
acquisition of Fero, Minova says it saw an
opportunity to partner with Split Set Mining
Systems “to provide the West Coast market with
an alternate ground support offer.”
Split Set Mining Systems, part of the Phoenix
group of companies, produces friction bolt
products, which are recognised around the
world. It also offers cable bolts, stabilisers, mesh
and steel arches, with a strong client portfolio
that includes BHP and Resolute Mining.
Split Set Mining Systems, with its bolts and
steel products, logistics and manpower, is
complemented by Minova, which contributes its
technical expertise, innovation and premium
products (including resin, injection chemical,
steel, fibre glass and ventilation control
products), to the joint venture.
As a result of the deal, Minova is no longer
manufacturing its steels and bolts from its
factory in New South Wales, eliminating costly
shipping via its partnership with Split Set
Mining. Minova also offers speciality products
and services for niche applications like optimised
ore recovery. Together the two companies will
offer the market local manufactured steel
products and warehoused resin and speciality
products and services.
“Our specialty products open the doors to
customers that they’re not particularly able to

contact,” states Minova
Marketing Manager Mandy
Lubbe. “We’ve always been
marketed as a technical
leader when it comes to
product development and
innovation around our resin
and chemical products.
These are premium in the
market and they work,”
Lubbe says.
Back in the Americas, International Rollforms
has also worked with Minova over the years but
in a looser form and it also use Epiroc as a
distributor in parts of the Americas. Terry
Karlsen, GM of the Split Set division of
International Rollforms told IM: “As far as new
applications, our product has not changed much
in the past 45 years and it is still amazing how
well this product is received and preferred by
mining customers all over the world. A truly
unique product.”
The DSI OneStep mining bolt
OneStep is a self-drilling mining bolt
from DSI which combines the drill head, drill
steel, bolt and adhesive resin in a single unit. “It
offers a unique value proposition since drilling
the hole, retracting the drill steel, resin capsule
insertion, bolt insertion and setting of the bolt
can be done in one single step. This permits
faster installation cycles and better installation
quality as well as ensuring that the highest
safety levels are achieved.”
The company says OneStep has developed a
strong position in both development applications
around rib support and also in longwall moves.
DSI says it has also consciously decided to go
against the trend of offshore manufacturing in
countries with low priced production conditions
and is creating additional jobs and a more
manageable and responsive supply chain for
customers in Australia.
“With this development, DSI sends a clear
signal in the development of new and innovative
products even if the market space is currently
stagnating. The ultimate aim is for the OneStep
to become a primary strata support product and
an important part of DSI’s Mining product
portfolio. The OneStep Bolt integrates itself into
the high quality offerings of DSI that are focused
on providing customers with unique and tailored
systems.”
Ass a resin anchor, the OneStep also now
provides longer shelf life through the use of DSI’s
own resin cartridges.
The Kestrel Coal Mine in Queensland, Australia
was experiencing difficulties in securing the ribs.
The OneStep Bolt was suggested as a solution,
and testing was carried out to determine the
peak shear load. Laboratory-based shear testing
DSI Schaum Chemie recently inaugurated its
new production, warehouse and testing
laboratories in Mikolów, Poland. The facility
holds a modern machinery and unloading park
with storage tanks, preparation and mixing
stations and a unit for packing finished
products. The laboratory will participate in the
control of production processes. The hall has
stations for manufacturing polyurethane,
silicate and phenol systems
indicated that the OneStep Bolt offers an
increase in shear capacity of approximately 15%
over the currently used fiberglass dowel. Product
trials showed that increased production rates are
possible through a reduction in rib bolt cycle
times. The mine has started a long-term trial, and
if this trial is successful, it will implement the
OneStep Bolt.
Posimix and Dynamix
The new DSI Underground Posimix Resin Bolting
System is designed to assist in the installation of
rock bolts with chemical anchors in larger
diameter holes (35-38 mm) by providing:
substantially enhanced mixing of the chemical
resin anchors – increased load transfer
capabilities – and the ability to be installed with
a face jumbo as well as hand held machines. The
Posimix wire centralises the bolt in the hole
allowing an even distribution of the chemical
anchor around the bolt. It also acts as an
Archimedes screw pump forcing the chemical
towards the back of the hole, assisting in mixing
whilst consolidating the anchor for improved
load transfer properties. The option of including
a debonded region on the bolt means the
majority of the energy is dissipated by
deformation of the bolt within this region.
The Dynamix resin anchored bolt system is
designed for high static load and dynamic energy
absorption. “The high strength bar consists of a
number of anchor points along the length of the
bolt, this combined with the addition of our
proven Posimix wire resin system ensures correct
resin mix for maximum load transfer in rockmass
conditions including rock burst and squeezing
rock areas.”
