Caterpillar has added the new AD22
underground truck to its hard rock mining
product line. The 22 t payload articulated dump
truck is the smallest in the Cat® product line, yet
it is designed to deliver the productive
performance and durability of its proven, larger
counterparts. Its small operating envelope and
agile characteristics enhance productivity in any
mining application suited for this size class.
The AD22 makes best use of proven Cat
components, such as the C11 ACERT™ diesel
engine. The durable engine delivers gross power
of 242 kW to achieve superior speed
on grade. The new truck shares
major components
with a number
of Cat
machines to
help ensure good
parts availability and
reduce inventory costs.
The wide body design makes loading faster
and easier. Multiple dump body sizes are
available to optimise the truck for all mining
applications suited to this size class.
The AD22 also takes advantage of Caterpillar
ergonomic designs to create controls and
instrumentation that help operators perform
efficiently. An easy-to-read full colour LCD
screen displays machine status.
Prior to the AD22 launch, Caterpillar Underground
Mining (CUGM) had acquired the intellectual
property of underground articulated truck designs
from Ground Force Worldwide. This provides
Caterpillar with additional design options in the
20 t and smaller payload class. The Ground
Force AT18E (18 t payload ejector) and AT20 (20
t payload) remain available for immediate order
via Ground Force Worldwide. The company
showcased the AT18E at MINExpo 2016.
This acquisition followed the September 2015
announcement of CUGM acquiring the
intellectual property of underground articulated
truck designs from Specialised Vehicle Solutions
(SVS). The new Cat® AD22 is derived from the
SVS UAT designs and is currently undergoing
field trials.
The new Cat R1700K underground LHD
features multiple engine configurations, a new
ergonomic operator cabin and greater payload.
The compact profile, efficient power train and
rugged construction deliver low cost truck
loading and LHD production.

ADTs have got up tocapacities of 60 t, like
this Bell B60E, andwill find their way
undergound
Joy Global’s 22HD LHD offers a bucketcapacity of 9 m3, static tipping loads of
48.2 kN, a breakout force (tilt) of 350 kN andan operating weight of 58,968 kg
The unit delivers a payload of 15 t, 20% more
than the previous model and supporting
efficient three-pass loading of the 45 t Cat
AD45B underground truck. After rigorous field
testing is completed this year, the R1700K will
be commercially launched in 2018.
To enable optimisation of the new loader for
lowest total costs in a specific application,
multiple engine configurations are available. All
options use the proven Cat C13 ACERT™ engine.
This engine can be configured for applications
that require compliance with the highest
emission standards in underground
applications, and it enables options for
customers who are striving to improve
underground air quality.
The R1700K is available in US EPA Tier 4
Final/EU Stage IV and in Tier 3/Stage III
emissions compliance configurations. The Tier
4/Stage IV engine employs the Cat Clean
Emissions Module, proven in millions of
operating hours on a broad range of Cat
equipment. The exhaust after-treatment
package components include a diesel
particulate filter and a selective catalytic
reduction catalyst to reduce both particulate
and NOx emissions to near zero. The R1700K C13
Tier 4 Final engine has a gross engine power
rating of 257 kW at 2,050 rpm.
For Tier 3/Stage III machines, Caterpillar
offers the Ventilation Reduction Package, which
uses select engine hardware and software
modifications to minimise particulate matter
emissions. Further particulate reductions are
available through the addition of an optional
diesel particulate filter, which features automatic
regeneration while the machine is working.
The R1700K operator cabin is designed to
promote safe and efficient operation throughout
the shift. An open ROPS/FOPS cab and an
enclosed cabin are available. Increased leg
room, multiple ergonomic adjustments, and
automatic climate control and filtered
ventilation in the enclosed cab enable operators
to work comfortably.
Simple and easy-to-use controls are at the
operator’s fingertips. Pilot hydraulic controls
enable precise operation with low effort.
Switches and control panels are located central
to the operator and within arm’s reach for fast
adjustment to the operation of the machine or
systems. The R1700K provides enhanced
visibility with an optional rearview camera that
displays its view on the easy-to-read colour LCD
monitor.
The monitor also presents live diagnostic
code feedback for faster repairs in the event of
an issue. The diagnostic codes refer to
individual circuits or functions that have been
monitored to display irregularities – enabling
technicians to identify causes quickly.
The R1700K has many new features—ranging
from simple to high tech. At the business end of
the machine, the newly designed bucket has an
increased throat angle to allow for faster filling
and better material retention during tramming.
New Cat Bolt On ground engaging tools (GET)
are designed for use in abrasive applications
where high wear rates make welded GET
impractical. The system also delivers more
available wear material for longer life and
greater uptime. Built-in wear indicators and
replacement corner segments allow the system
to be integrated into scheduled maintenance
regimens.
The innovative traction control system
enables the R1700K to control drive power to
each wheel independently. The result is minimal
tyre slip, optimum traction, and the ability to
penetrate the pile more effectively for fast
loading.
The R1700K also delivers significant
technology enhancements. It is equipped with
multiple subsystems for fast technology
implementation. The Cat line-of-sight remote
control systems allow operators to control their
machines from safe distances, and the Cat
Command for underground, semi-autonomous
system enables operators to work from a remote
location. Remote machine health monitoring,
payload monitoring and other technology
options can be installed at the factory or in the
field.
Paus considers that bad road and narrow
conditions as well as sharp corners “are
probably the most mentioned characteristics in
conjunction with underground mining.” Loading
and hauling often become work tasks requiring
millimetre accuracy “because you have to go out
the same way you came in. In case you need a
turnaround, the radius could be extremely small
and the only thing that counts at this time is
how long the vehicle is. Paus developed for
these and other instances the LHD PFL 20, a 4 t
loader compact and optimised with a length of
only 7.30 m.”
The Paus loader range offers many problem
solving options for mining. Constructed with
ROPS/FOPS canopies and with payloads
between 1.5 and 9 t, there are different sizes for
different needs and even flameproof vehicles; by
way of example the Paus LHD PFL 30S as a
regular or flameproof vehicle. The loader has
had a new face lift and a new design for more
safety and mobility. For instance the driver’s cab
has been given more stability and comfort
through the provision of more space. To mount
the machine, operators can now enter directly
through a side access instead of having to
confront the articulated joint behind the
kinematics.
The kinematics have also changed from the
former parallel to the better Z-kinematics “to

give more power and to increase dumping. That
means for users easier handling, time saving and
better operating efficiency. Always an aim is to
optimise the sight aspects in underground
mining in general. The design team of Paus
reduced the rear part and optimised the motor-
block to be more compact so that the driver’s cab
is high enough for a better sight backwards.”
As flameproof machines under the EU ATEX
regulations, the engine temperature is supposed
to be no higher than 150°C. “That means Paus
needed to implement a contrived cooling
system.” A five-step cooling system now ensures
proper temperature control. The exhaust gas is
cooled through the in- and outside of the lines.
“On request this awesome cooling system is even
able to cool to an exhaust gas temperature of 70
°C only. Additional flame arrestors placed at the
exhaust gas and air intake lines guarantee for
even more safety as well as the capsuled electric
parts.”
A further gas issue is mine gas (methane,
hydrogen gas) in shafts. “Getting a warning and
still having enough time to get out in safety is not
rarely a question of time. Intelligent sensors are
installed into the driver’s cab to send out a signal
as soon as gas will be detected.”
But there are also further aspects which
influence the health of underground workers in
an extensive way; a huge dust exposure, the
permanent rocking motions of the vehicles while
driving and last but not least the continuous
noise pollution. “Dust is not easy to handle,
there will be always a vibration or shaking while
working with vehicles and of course underground
will always be a place where machines will sound
louder as an average. The only way of protection
would be an automation of machines and the
driver will control the operational work from a
distance. The Paus loader range is constructed
and contains tools for installing remote controls.”
In addition to the successful loaders Paus has
developed a dumper series with some special
features.
As mentioned before, roadways can be very
tight and in most of the vehicles the driver sits
sideways to be able to look in both directions,
“of course because you are going out the same
way you came in.
“But after a while the driver has to fight
against losing concentration and neck/shoulder
problems and the safety aspect for a better sight
is affected. As solution and help to ease these
requirements, Paus builds and offers the dumper
with only bi-direction driver’s cabs for best sight
to both directions.”
Additionally these trucks are available as a
concrete mixer or with an integrated pusher so
that loaded material can be fully ejected at the
rear in case of low ceiling heights.
“Challenges in loading and hauling are the
motor to keep engineers being innovative and to
motivate teams at Paus for offering efficient
solutions.”
Low profile specialsSandvik’s wide offering covers underground
loaders and haul trucks for mass mining, low
profile and narrow vein applications. The Sandvik
LH208L, for example, is a 7.7 t capacity LHD built
for operation in low-profile room-and-pillar mines
and extra-low-profile reef mines. It operates in 1.7
m seam heights for low profile applications in
platinum, chrome and potash mines.
Sandvik has a large installed base operating in
South Africa and well established customers who
operate large fleets. There are also have
installations in Russia and Brazil.
The LH208L has the Sandvik boom geometry
that results in more powerful break-out force,
allowing for easier loading and higher bucket fill
factors. This also assists loading when on a
gradient “and this machine is significantly more
powerful than its competition. It is also robust
and easy to maintain,” Sandvik reports.
“To make the Sandvik LH208L even more safe
and productive a number of upgrades have been
made.”
The Sandvik OptiMine® Data Collection Unit is
standard, collecting data from the machine on
operating hours, temperatures, pressures and
speeds. The customer can also upgrade the
system to Sandvik OptiMine Monitoring and
Reporting as an option in order to get access to
automatic reports that present this data that is
collected in a form that assists the mine to gain
visibility over what the machine is doing. This
allows the mine to use this data to improve
productivity and make key decisions on a shift by
shift basis regarding maintenance of the unit.
A fully integrated weighing system will soon
be available as an option that measures the
weight of ore in the bucket and the number of
buckets completed by the operator. This
measurement is also logged as part of the
OptiMine Data Collection Unit and used in the
productivity reports.
Customers can also choose to have an
interface installed on the machine that allows
them to connect a third party Proximity Detection
System (PDS Interface). This allows an active PDS
where the machine speed is reduced when a
person is detected within the warning zone and
then to bring the machine to a safe state when a
person is detected in the stop zone. This helps to
prevent collision accidents between the
equipment and pedestrians in the mine. Added

functionality also allows for Speed Brake
Interlock where the machines’ speed is
monitored and when the machine travels over a
predefined setting the operator is given a
warning to slow down; if no action is taken then
the machine speed will be automatically reduced.
A safety report showing the events raised by the
PDS is also available when OptiMine Monitoring
and Reporting is selected.
There is a larger 3.5 m3 bucket option, rather
than the standard bucket which is 3.3 m3.
Another thing to remember in low profile (or
narrow reef) mining is that due to the height
restrictions and the gradient in the tunnel
following the reef it is not possible to complete a
heaped load in the bucket. For this reason
Sandvik has designed a bucket that specifically
assists in gaining more tonnes from non-heaped
bucket filling for low height seams.
There is improved lighting with heavy duty LED
lights as standard and for improved visibility
there is an on-board camera system fitted to all
machines.
There is a side-mounted swing out cooling
package for easier cleaning and harsh conditions
where there is a lot of water:
n Easy to clean trial unit
n Tough design in severe conditions, not as
easily exposed to mud and dirty water
n No down time on cooling unit components,
motor, fan blades and hydraulic hoses
n No transmission overheating
n No additional parts used in trial period.
There is a Tier 3 engine option as Sandvik is
pushing to make available on its equipment
range lower emission engines.
In addition to the compact DUX Machinery
model DT-5N, 5 t payload, 1.42 m wide diesel
powered dump truck sold to a narrow vein copper
mine in the USA last year, DUX is planning to
introduce a very compact model DSL-300 LHD
with 3 t tramming capacity and 1.22 m³ SAE
heaped bucket capacity, which measures only
1.44 m wide. Both the DT-5N and DSL-300 models
are well suited for small deep narrow-vein mines
and construction projects. Both share a similar
platform and will be available later in electric
versions. DUX is also in the process of designing
a DT-40E electric haulage truck with 40 t payload
capacity.
ADTsVolvo Construction Equipment’s (Volvo CE)
articulated hauler offering, which recently saw
the introduction of a the new 45 t class A45G,
now includes the latest, 55 t capacity A60H,
offering a 34% higher payload than the previous
largest A45G. It could prove a highly productive
solution underground. In situations where
loading height and turning space would not
restrict a vehicle of this size in underground
operations, the A60H could provide for a
significantly lower cost per tonne. Despite its
size, its turning circle, at 10,014 mm, is not
significantly greater than the 8,957 mm of the
A40G/A45G.
Where there may be access issues, Volvo’s
A25G Twin Steer option can provide a good
solution. Modified to simplify long distance
reversing in tunnels, the Twin Steer features dual
controls. Rotation of the operator’s seat through
180° determines which controls are activated and
allows the operator to be always facing the
direction of operation. When the rear controls are
activated – steering, throttle and brake – long
distance reversing is easier, with speed reduced
to 13 km/h as an additional safety factor.
A rear window wiper and slats in the rear of
the dump body improve visibility when unloaded
and a side dashboard improves operator comfort.
Safety is further enhanced with a rear vision
system, comprising a camera and in-cab monitor,
four halogen lights facing the rear, extra mirrors
and an amber flashing beacon mounted in the
rear part of the machine, providing high visibility
when operating in tunnels.
No stranger to underground operation either
and increasingly an option where dimensional
limitations allow their use, is Volvo’s extensive
range of wheel loaders. Highly manoeuvrable and
adaptable they provide for fast and efficient
loading where space is restricted; a factor than
can benefit an operation’s bottom line as well as
the production rate.
Volvo wheel loaders are adept at working with
multiple attachments; one machine fitted with
the Volvo quick coupler can perform multiple
jobs, reducing the fleet needed underground.
The Volvo side-tilt bucket, for example, has
proven reliable in limited space environments
and can dramatically increase production rates
by eliminating the conventional “Y” loading
pattern.
The latest technologies include lockup
transmission converters, Volvo-patented
OptiShift technology with reverse-by-braking,
safety controls and systems, and on-board data
logging and diagnostics (with telematics
connection where capable) to assist service
planning.
As for haulers, an optional low profile cab is
available to reduce the overall working height
without impairing operator visibility, factory-
fitted fire suppression systems, cameras and
various lighting packages to increase visibility in
poor light conditions. Optional, fluorescent
highlight strips available for wheel loaders
provide an additional safety feature.
A variety of guarding packages can be applied
to the cab, windows, radiator/rear, hydraulics
and driveline to customise protection to specific
needs; the majority are bolt-on/bolt-off
assemblies designed to fit the machine, allowing
smoother replacement.
All cabs are ROPS/FOPS certified; brakes and
other primary systems meet or exceed
international standards. Filtration solutions are
available to mitigate dusty environments, both
for engine air intake and for cab protection and
treatment packages can be applied to address
corrosive or high/low temperature environments,
increasing reliability and uptime.
The latest Volvo L260H and L350H are
particularly suited to underground production at
the face, as the Volvo Z-bar linkage generates
tremendous breakout forces at ground level,
allowing the bucket to be completely filled with
minimal raising of the boom.
With ventilation an important consideration,
Volvo’s latest, highly fuel efficient, Stage IV/Tier
4 final emissions technology offers cleaner burning
engines and minimal exhaust emissions. In Canada,
for example, the latest A25G/A30G haulers are
CANMET registered for underground use.
Volvo CE is also actively engaged in
investigating future solutions. Participation at the
Swedish Mining Initiative (SMI) in Toronto in April
this year serves as just the most recent example
of keeping in touch with developments and
customer needs. Organised by Business Sweden,
exchanges around best mining practices and the
future of the mining industry provided an
opportunity for Volvo CE’s former Vice President
UNDERGROUND LOAD AND HAUL
50 International Mining | JUNE 2017
of advanced technology and verification, as an
invited panelist, to share Volvo’s current work
around electric power in mines.
With its never-ending consideration for the
environment, Volvo is investing heavily in
alternative solutions – alternative fuels, hybrid
technology and electrification. Such alternatives
contribute not only to reduced fuel consumption,
but, equally important when working
underground, further reduction in emissions and
noise pollution.
At the company’s Xploration Forum event held
last year in Eskilstuna, Sweden, attended by
customers and others, Volvo CE showcased some
of the fruits of its investment. Presented under
the umbrella of ‘Volvo Concept Lab’ – a new Volvo
Group initiative – the event saw the unveiling of
the LX1 prototype hybrid wheel loader – a
machine with the potential to improve fuel
efficiency by up to 50%; demonstrations of a
prototype autonomous wheel loader and ADT
working together, and an electric site solution
that showcased the new concept HX1
autonomous, battery-electric, load carrier.
Volvo CE has teamed up with its customer
Skanska Sweden, the Swedish Energy Agency
and two Swedish universities – Linköping
University and Mälardalen University – to
collaborate on this SEK203 million electric site
project.
With clear implications for mining/
underground mining, the electric site project
aims to transform the industry by reducing
carbon emissions by up to 95% and total cost of
ownership by up to 25%. All of the innovations
shown at the Xploration Forum are ongoing
research projects that aren’t commercially
available at this stage.
Volvo CE continues to develop technologies
connected to electro-mobility, intelligent
machines and total site solutions to benefit its
customers and the environment by contributing
to increased machine performance, productivity,
efficiency, safety and sustainability.
Bell Equipment last year launched its B60E,
elevating the design and performance of the
original B60D to the next level. Described by Bell
as “the next generation”, its 4x4 full articulation
steering and oscillation joint “provides more off-
road capability than any other conventional rigid
truck and its Mercedes Benz engine offers the
lowest cost per tonne on the market.”
The B60E was presented along with the
company’s new E-series large trucks for the first
time in North America at CONEXPO 2017.
Featuring the new E-series truck styling and
features, the range includes the latest generation
Mercedes Benz engine, certified for off-highway
use by MTU, with an Allison transmission.
The B60E is an ADT with a single rear axle
instead of the more typical double axle. The
traditional ADT characteristics of all-wheel drive,
oscillation joint and articulation steering are
maintained to deliver a proven competitive
alternative to both rigid dump trucks and
traditional ADTs.
Bell Equipment Product Marketing Manager,
Tristan du Pisanie points out that when compared
to other ADTs, the B60E offers a level of
productivity never seen before. "While the two-
axle configuration does not have the same level
of off-road ability that a three-axle ADT has, due
to the higher ground pressure at the rear, there
are many ADT customers who do not need all of
the capability of a traditional ADT and the simpler
B60E is a great solution. In addition the B60E has
almost no tyre scuff, a major sore point for the
middle and rear axles of a three-axle ADT. We
have sold a number of B60s to ADT customers in
various parts of the world who are running the
B60E very successfully and enjoying the
increased productivity it offers."
The B60E shares the B50E front chassis
powered by a EU4/Tier4final certified 430kW
Mercedes-Benz/MTU inline six-cylinder engine
combined with Allison’s secen-speed
transmission. Braking and retardation of the
42.5/97.5 t 4x4 is assured by wet brakes on all
wheels in combination with powerful Jacobs
Vehicle Systems® engine braking.
The rear chassis is a completely new design
and incorporates all practical experiences and
analytical data gathered in the extensive four-
year test program with B60D prototypes and
production machines working in mining
operations in South Africa. Now featuring a
suspended 70 t rear axle with 24.00 R35 twin
tyres, the nominal payload is rated at 55 t. Far
larger than a conventional ADT bin, the flat-
bottomed 35 m³ body resembles a rigid-truck bin
in its dimensions and geometry, which makes it
fully compatible with existing loading equipment
in mines and assures an ideal 2:1 heap of coarse
blasted material.
The truck has proven its versatility on
customer sites easily managing steep gradients,
tight turning circles and poor underfoot conditions.
Narrow vein optionsAramine continues to develop innovative
machines for narrow vein mining. The company
reasons that the flexibility of development and
the lower capital investment required allow faster
return on investment especially in these days of
big fluctuation of raw material costs.
The French company offers a complete range
of narrow vein machines integrating the latest
technologies such as battery, radio remote
control and the relevant regulations in terms of
safety and ergonomics that are motivating mining
companies to develop narrow vein mining.
Aramine’s miniDumper T500 is a simple and
reliable truck for underground mining work in
narrow vein applications.
Based on the power frame and components of
the L150D LHD, the T500D miniDumper will help
the customer to keep control of parts inventory
and fleet rationalisation.
With its four-wheel drive, heavy duty
articulated frame and oscillating axle, the T500D
will smoothly carry loads in the toughest road
conditions and short turning radii of underground
narrow vein mines.
The dumpbox, with a height of 1,500 mm, has
a safety raised locking device and can be
equipped with or without wide opening
automatic rear tailgate.
Because safety and comfort are always
Aramine priorityies, the operator’s compartment
offers a high comfort seat with adjustable
UNDERGROUND LOAD AND HAUL
Volvo CE’s new concept HX1 autonomous,battery-electric, load carrier
suspension, a safety door and a ROPS/FOPS
certified canopy with back protection. Plus, the
operator is side seated for better visibility in both
directions.
This truck is capable of carrying 2.1 m3, three
times the capacity of the L130D/E miniLoader at
speed.
As noted in last month’s World Prospects
section Aramine also has two new 15 t capacity
mine trucks in its product line. The French
company has put on the market the T1601C and
the T1601M. Developed for small to medium scale
underground operations, both T1601 models are
described as ideal for drift sections of between 12
and 18 m2 and they fit into 3 m x 3 m galleries.

Hydrogen power?In a promising development for underground
propulsion units comes news from CSIRO that its
research aims to fill a gap in the global energy
technology chain to supply fuel cell vehicles with
low-emissions hydrogen sourced from Australia.
The two-year project will build on CSIRO's
expertise in separating pure hydrogen from
mixed gas streams, in this case converting
ammonia to high-purity hydrogen for use in fuel
cell vehicles (FCVs).
CSIRO's membrane reactor technology will fill
the gap between hydrogen production, distribution
and delivery in the form a modular unit that can
be used at, or near, a refuelling station.
Currently, the transportation and storage of
hydrogen is complex and relatively expensive,
making export commercially challenging.
The membrane will allow hydrogen to be
transported in the form of ammonia (which is
already being traded globally), and then
reconverted back to hydrogen at the point of use.
The thin metal membrane allows hydrogen to
pass, while blocking all other gases.
In the final stages of development, the device
is being further refined, ready for commercial
deployment. IM
Tyres on LHDs and underground trucks getmuch greater life running on well-maintainedunderground roadways. Miller Technology’s BG110-M was developed in collaboration withmining specialists especially for use in miningapplications. Its height is only 1.80 m andoverall length without attachments less than7.40 m. Thanks to the hydrostatic all-wheeldrive, the driver can alternate the speed at willin that gear. A high starting torque ensuresmaximum thrust even at low speeds andrevolution speeds. The two-gear transmissionin use enables the grader to move at amaximum speed of 33 km/h.
