Komatsu Mining Corp will

be led by Jeffrey Dawes,

formerly leader of Komatsu Latin

America. Dawes and the management team will

be based in Milwaukee.

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.

48.2 kN, a breakout force (tilt) of 350 kN andan operating weight of 58,968 kg

Page 2: UNDERGROUND LOAD AND HAUL Muck shifting - Aramine Mining 2017-06.… · improve productivity and safety in their ... UNDERGROUND LOAD AND HAUL Muck shifting Some of the main ... regeneration

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

UNDERGROUND LOAD AND HAUL

44 International Mining | JUNE 2017

Caterpillar’s new AD22 truck is available withan open operator compartment or an optional

enclosed cab. Both are ROPS/FOPS certified.The sweeping deck design provides good

sight lines around the front of the truck, andthe LCD screen shows the rear-view camera

view when backing

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

UNDERGROUND LOAD AND HAUL

The Paus PFL 20 is a favourite for working witha remote control system; innovative and wellproven with easy handling

48 International Mining | JUNE 2017

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

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

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.

Electric powerWe have devoted significant editorial space

examining the growing use of and offerings in

electrical power for underground machines. It is a

very important developing trend.

Canada’s RDH Mining Equipment, which is one

of the leaders in battery powered mining

equipment development, bringing battery power

to the North American and Asian markets, is now

working with strategic partners in Latin America

to assist mines in transitioning to battery power.

Sierra Metals, committed to being a leading

corporate citizen in Peru, has taken the first step

in transitioning to battery equipment with a RDH

battery powered LHD at its Yauricocha mine. As

the first mining company in Latin America to

make the transition to battery powered mining

equipment, Sierra Metals, with a focus on

continuous improvement, said it could not ignore

the health, environmental, operational and cost

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. The open canopydesign with its readily accessible controlsprovides excellent ergonomic workingconditions for the operator and eliminatesdriver fatigue. The electrical equipment boastsa very high degree of protection for workunderground. The load-sensing hydraulicsystem supplies the loads only as required andaffords a flow control independent of the load.This allows the control valves of the workinghydraulics to be actuated simultaneously orindependent of one another Settling ponds cause profit-draining downtime and environmental

headaches. McLanahan Corporation offers a custom engineered processing solution to help you recover more fines, while saving time
