The German mining machinery manufacturers achieved a record turnover in
2009. And the sector is hoping to continue this through into 2010. Since the
successful integration of the area of mining into Hall C2 at bauma, this
section is enjoying very high demand. Many new developments and innovations
await visitors at the stands of manufacturers of machinery for mining, tunnel
and gallery construction and special foundation engineering at bauma, but below
we have picked out just some of those that will be of particular interest at
bauma 2010.
Among the brands which come under the umbrella of the ABI Group, a producer of specialist
machinery for civil engineering, are ABI, BANUT, DELMAG and INTEROC. The latter
was taken over in 2009 from deilmann-haniel mining systems GmbH. The AN 150, on
show at bauma, has a 149 kW engine and can be used for anchor drilling, micro
piling and HDI drilling. Rod changing is facilitated by the circular arc
magazine KBM 150: Even when used at an angle, this anchor drill can take up to
seven double head systems with a maximum pipe outer diameter of 152.4 mm.
Working with this circular arc magazine is efficient because the head systems
can be fitted and removed quickly and safely. The AN 150 is driven by a Cummins
diesel engine with turbocharger, meeting the current emissions values.
The new hydraulic hammer presented at bauma by Atlas Copco is fitted with PowerAdapt, a system which automatically
switches the machine off when the oil pressure becomes too high. This is
particularly useful when the hammer is being used on different carrier
equipment, because hydraulic hammers can become overloaded hydraulically if the
oil pressure on the carrier equipment is not set correctly. As these hammers
are subject to the toughest of conditions, the improved guide system brings
improved stability and resistance. With a weight of around 3150 kg, the HB 3100
can be fitted to carrier equipment in the 30- to 52-tonne class.
The 'down-the-hole flushing head for dry-drilling rods' from Bauer Maschinen GmbH was nominated for
the bauma Innovation Award 2010, in the 'Machine Component' category. When this
down-the-hole flushing head reaches a hard layer of rock it can be fitted to
the Kelly bar together with a disc
cutter full-face cutterhead positioned underneath or with a disc cutter core
drill. When the drilling tool is standing on the base of the drill hole and is
pressed via the thrust of the drilling device, a lever mechanism spreads the
stator of the down-the-hole flushing head against the wall of the drill hole.
This ensures that the connection to the compressed air pipe does not rotate
along with the rotor which passes on the rotation of the Kelly
bar to the drilling tool.
With some types of rock, the drill rods have to be cleaned each time
they are pulled out. And even in the dirty conditions of mining, quarrying or
building sites, machinery needs a regular wash. Portable cleaning systems are
ideal for this application. One such new system, exhibited for the first time
at bauma 2010, is a hot-water high-pressure cleaner HWBBW50Kpi from Brendon Powerwashers.
A diesel-driven water-plate heat exchanger heats the water to 78°C. The system
uses a part of the waste heat from the boiler to pre-warm the buffer tank for
hot water. The high-pressure cleaner works with maximum pressures of 238 to 340
bar and a flow of 12.5 l/min.
The longwall conveyor and plow-drive control
system PMC-D/V for underground mining was further developed by Bucyrus and now offers vibration
management (VM) for better protection of mining equipment. The system, called
VibraGuard, enables trained personnel to predict machine component wear, avoid
unplanned downtimes and set alarms to warn the operator about the danger of
damage to the monitored machine components. To meet customer wishes, the
functionality of the PMC-D system has been extended. A digital signal processor
converts incoming acceleration data into spectrum data, which are then
transferred to a service PC. The data are evaluated and visualised by the
VibraGuard visualisation software installed on the PC.
Continental is offering its tyres for heavy-duty earthmoving machinery under the
brand name of Simex. The wide-based tyre Simex SE65 is especially suited for
use with wheel loaders and bulldozers which are used in the toughest conditions
in quarries or in mining. These tyres have a very deep tread. The almost flat
profile ensures good load distribution and the opposing cross grooves give
excellent traction. The rubber mix used is largely resistant to cuts and
abrasion.
The automated shearer loader SL750 EIControlPlus from Eickhoff Bergbautechnik GmbH has been
nominated for a bauma Innovation Award in the 'Machine' category. Using this it
is now for the first time possible to do automatic longwalling in coal mines,
where the operator is merely monitoring operations, in a secure, unpolluted
environment. Thanks to a system of interlinked infrared cameras with image
processing and body sensors, environmental monitors, millimetre wave radar to
avoid collisions and visual cameras, the machine can independently recognise
the deposit boundaries, thus delivering automatic control of all operations in
the extraction process along the coal seam. Unnecessary extraction of undesired
surrounding rock is thus avoided. This saves additional energy input and carbon
emissions.
The new generation of load-haul dumps (LHDs) with efficient drive system
(EDS) from GHH Fahrzeuge GmbH for
tunnel/gallery construction and mining offer advantages in terms of their small
dimensions, energy efficiency, improved productivity and ergonomically designed
workplaces. As the road conditions in tunnelling and driving demand that when
both loading and braking all four wheels must transmit drive and braking force,
the axles are mechanically connected with each other. The combination of a
modern diesel engine, hydrostatic power transmission and mechanical drive
concept brings fuel savings, improved user comfort and a reduction in emissions
in underground applications.
Haver Engineering Meißen (HEM) does research and development work in the areas of
agglomeration/pelletizing and cleaning plant for building materials and
minerals on behalf of the HAVER & BOECKER international group. HEM is an affiliated
institute of the Technische Universität Bergakademie Freiberg. As a result the
latest findings from scientific research are used in their project work.
Scientists from the university are now joining the team of experienced
engineers and specialists, and new resources are being made available. HEM
supports its customers from concept phase through to production, along the
entire product-development process, in the development of components, machinery
and plant. In each project the customers benefit from the development
competence and experience of the company and from the latest technological
developments, materials and findings from the Technical University.
Herrenknecht AG delivers tunnel boring systems for diameters from 0.10 metres to 19
metres. The range of products includes custom-made machinery for transport
tunnels as well as supply and disposal tunnels. The company has now developed
Direct Pipe, a process that combines the advantages of microtunnelling and
horizontal directional drilling (HDD): in just one continuous operation, a
borehole is drilled and a prefabricated pipeline inserted. As with pipe
jacking, earth excavation is by means of a microtunnelling machine. The force
required to feed the pipeline forward is exerted by a new type of feed
developed by Herrenknecht, called the Pipe Thruster.
A new connector for aluminium beams is presented by Friedr. Ischebeck GmbH. TITAN 225 aluminium beams can be combined
by means of a shear-resistant connection with the desired bending stiffness and
length. The aluminium beam connector opens up new applications for bridging
access openings, where in the past only steel beams (HEB profiles with welded
bulkheads) could be used. The latter are affordable and robust, but
unfortunately cannot always be joined with the bulkheads in the right, desired
positions. In addition such HEB rolled profile steel beams are difficult to
dismantle. All of this is now made easier with the new aluminium beam
connector, with 5 HV screws, a length of 460 mm and a weight of just 1.5 kg.
The TITAN 225 aluminium formwork beams can be dismantled for removal to the
extent that they can be handled and carried away by one man.
Knauf PFT GmbH & Co. KG has developed new machine systems for use in the
exploitation of geothermal energy. These systems ensure cavity-free filling of
the deep holes drilled to tap into geothermal heat. There are two types of
system: In the case of the 'open system' the filler building material is mixed
in batches in a PFT MULTIMIX batch mixer and transferred to a downstream
conveyor pump PFT N 2. Via the worm shaft of the PFT N 2 the material is pumped
to the mortar pump and pressed into the bore hole through the pump hose. With
the 'closed system' cavity-free filling is carried out by just one machine: the
dry material is passed to the machine, which then mixes it and continuously and
fully automatically pumps it into the bore hole.
At bauma Liebherr will be
presenting a number of new developments for applications in mining and
tunnelling. Designed for use in extraction operations, the crawler excavator
R 954 C SHD achieves a digging force of up to 435 kN / 44.3
tonnes and breakout forces of up to 355 kN / 36.2 t. Its wear-resistant
shovel has a capacity of 3.5 m³. Because of the shovel form, good penetration
into the material and a high level of filling is guaranteed. Two different
requirements profiles apply to the use of excavators for tunnelling: on the one
hand very high-performance excavators are needed for the excavation of tunnels
with large cross sections. On the other, short-tail excavators are increasingly
in demand for driving out railway tunnels or auxiliary tunnels, as well as for
renovation work in existing tunnels. For over 20 years Liebherr has been
manufacturing hydraulic excavators for use in tunnel construction. The new R
924 Compact Tunnel achieves an advance of up to 2.50 m. Its maximum digging
force is 135 kN and it has a maximum breakout force of 85 kN.
To cut through steel cord conveyor belts, you need the right tools. One
such tool, developed specially for the job, comes from NILOS GmbH & Co. KG – its belt-cutter ROTOCUT. Nilos supplies
two electrically operated versions, the RCE 20 and the RCE 40, plus a
mechanical version RCM 20. As the latter is not electrical, it is suitable for use
in underground mining. The toothed cutting wheel cuts into the belt from above
and in doing so sets the two lower, smooth cutting wheels in motion: the belt
is cut through shear action. The teeth in the upper toothed cutting discs are
arranged in such a way that one steel cord fits between two teeth, the cord
being sheared as the disc rotates. This happens also with the manual lever
drive of the RCM 20 which can be operated without the need for great force; an
amazing feat in view of the thickness of the steel cables! This cutting
technique has been patented by NILOS GmbH & Co. KG.
When drilling wells for drinking water, gravel or sand has so far been
used as a supporting material in the space between the instable bore hole wall
and the well filter drill. OCHS
Bohrgesellschaft GmbH uses glass beads instead. This innovation was
nominated for the bauma Innovation Award in the category 'Construction work and
processes'. The smooth surface of the glass beads guarantees a more economic
operation of the water well. The water flows unimpeded between the glass beads.
This can lead to high savings potential in terms of the electrical energy
needed to pump the water up from a great depth, because the overall water table
is not reduced as much through the operation of the well.
Sandvik Mining and Construction will be presenting their new impact crusher QI 240 at
bauma. In development the focus was primarily on the crushing of recycling or
building materials. But because of its compact design, the model is also suited
for use in smaller quarries where there is little space to manoeuvre, but where
first-class product quality and high throughput are required. The QI 240 is the
first of a new series of mobile crushers and screens that Sandvik will be
launching in the coming months.
In quarrying, mining of solid rock and on building sites, powerful
crushers are what´s needed. SBM Mineral
Processing GmbH has redesigned its universal crusher series and brought
them together in the new Series 13. The 13/16/4 RHSMK-3 impact crusher has a
fully hydraulic impact apron. This model is based on a robust, but effective
combination of mechanical and hydraulic adjustment and guarantees good
protection when foreign bodies enter the crushing chamber.
Tenova TAKRAF has developed a pit-crushing system consisting of a
mobile crusher, transfer conveyor and spreader. The mobile crusher, from the
TMCS series, was designed for a new coal mine in Queensland,
Australia.
It works with a maximum crushing power of 12,000 t/h, which probably makes it
the number one mobile crusher worldwide. It can break down hard stone material
(e.g. basalt) with lengths of up to 1200 mm to a transportable grain size of
350 mm which is suitable for conveyor transportation. In face operations the
TMCS 12000 moves along the face with the excavator and passes the material
extracted either direct or via a transfer conveyor to the face conveyor. Using
mobile crusher systems means there is no need for heavy-duty vehicles to remove
the overburden. This considerably reduces not only the road-building
construction costs in mining, but also diesel and tyre consumption, staffing
costs and not least carbon emissions.
For special civil engineering applications, ThyssenKrupp GfT Bautechnik supplies sheet pile profiles, machinery
and equipment. This encompasses steel sheet piling, driving, drilling and
pressing technology, trench shoring and anchor equipment and flood protection
systems. The area of anchor technology has been continuously further developed
in recent decades. Considerable improvements have been made in high-performance
anchors, as well as in the processes to improve load-bearing capacity overall.
Here this includes above all anchors that are used where there is pressing
water and a high water table, and anchors to secure excavations and quay walls
as well as rock walls, for example against the risk of avalanche and rock
impact.
The surface miners from Wirtgen
GmbH for mining minerals have cutting widths from 2.20 to 4.20 m and
cutting depths of 20 to 83 cm. The 4200 SM model is being presented at bauma
for the first time. This is available in two configurations for use in hard and
soft stone: for soft-stone applications up to a single-axle compression
strength of 50 Mpa, the 4200 SM is fitted with a cutting module of 4.20 m
working width with a larger diameter cutting circle. This enables a cutting
depth of up to 83 cm. In addition a unit with a cutting width of 4.20 m and a
cutting depth of 65 cm of hard stone, with a single-axis compression strength
of 30 to 80 Mpa is available for the largest Wirtgen miner.
