Specialist machine for soft rock mining
Surface Miner 2200 SM 3.8
Economical mining of soft rock
Mining soft rock at maximum
production rates and econom-
ic efficiency – the 2200 SM 3.8
surface miner has been developed
to meet exactly these criteria for
success. The centrepiece of the
compact, yet powerful machine
is the 3.8 m wide cutting drum
which offers numerous innovative
features. It cuts soft rock with un-
confined compressive strengths of
up to 35 MPa, such as coal or salt,
in a highly productive process,
depositing it in three windrows
behind the machine.
The cutting drum unit represents
state-of-the-art technology –
based on optimizations that were
the result of extensive field testing.
It offers maximum cutting per-
formance while fully utilizing the
machine’s engine power at the
same time. Further positive effects
include low specific fuel consump-
tion rates, optimized tool use and
minimized fines content as a result
of gentle material transport.

Drilling Blasting Loading Crushing
Cutting drum unit precisely tailored to the mining of soft rock
The robust, 3.8-m wide cutting
drum assembly is based not only
on fi eld-proven components but
also on concepts specially de-
veloped for the highly productive
mining of soft rock. The cutting
drum housing consists entirely
of highly wear-resistant material.
Effective closure of the drum
assembly on the left and right is
ensured by two hydraulically lifting
side plates. The integrated water
spray system reduces dust devel-
opment when cutting dry useful
minerals. Three large material
discharge openings in the scraper
blade allow large amounts of
material to be deposited in three
windrows behind the machine.
Different types of highly wear-
resistant mining tools cut rock with
unconfi ned compressive strengths
of up to 35 NM / mm². Ready
access to the cutting drum and
the hydraulic drum turning device
additionally allow for easy tool
replacement.

1 The drum’s large cutting
diameter guarantees both high
working depths and high mining
volumes.
2 The high, slender toolholder
bases play a critical role
in guiding the material as
effi ciently as possible.
3 Maximizing the tool spacing
minimizes the number of cutting
tools, thus reducing the cost of
wear.
4 Cutting tool arrangement and
tool spacing minimize the fi nes
content.
5 The cutting drum, which has
been specially developed for the
windrowing process, does not
require conveying helices, thus
minimizing energy requirements.
6 Large openings in the scraper
blade ensure an effi cient, effort-
less fl ow of material.
Innovative features
The material is deposited in three windrows for immediate pick-up by wheel loaders.
A cutting width of 3.8 m and cutting depth of up to 350 mm guarantee high mining volumes.
Controlling the 2200 SM 3.8 with the greatest ease
Inside the cabin, the operator is
protected from outside influences
such as extremely high or low
temperatures, wind, rain, dust,
vibrations or high noise levels. The
spacious, anti-vibration mounted
cabin is sound proof and features
a heating and air-conditioning
system. These comfort features
prevent fatigue and allow produc-
tive working for extended periods
of time. Relaxed working is, of
course, also promoted by good
visibility and ease of operation.
To provide a full view of the
working area, the cabin features
large glass windows and extends
beyond the sides of the machine
on the left and right.
At the same time, the operator
has a good view to both sides and
immediate access to the controls.
Both control panels can be moved
far to the left or right and adjusted
individually. In addition, the miner
is equipped with the LEVEL PRO
electronic automatic levelling
system for cutting depth control
which quickly and precisely cor-
rects any changes in the reference
plane.
Relaxed working boosts productivity

Operation from the left or right: the two identical control panels have a small number of buttons and switches and can be separately adjusted in height, pivoted or moved to either side.
Ample space, ergonomic design, comfort features and good visibility
ensure operator comfort.
Excellent manoeuvrability on difficult jobs
The 2200 SM 3.8 features a
finger-light hydraulic all-track
steering system which gives
all four track units large steer-
ing angles. The advantages are
obvious, especially when working
in restricted space conditions: the
inner turning radius of only 2.5 m
and crab steering mode allow fast
manoeuvring. In addition, sepa-
rately height-adjustable track units
ensure high ground clearance:
they facilitate operation on uneven
ground, reverse travel or machine
loading. An engageable hydraulic
differential lock additionally pro-
vides optimum traction regardless
of ground conditions. The miner’s
operating and travel speeds are
continuously adjustable.
The 2200 SM 3.8 also features an
amazingly high climbing ability and
tremendous longitudinal inclina-
tion which enable it to be used for
operations in difficult peripheral
areas or for the production of
separate access roads and ramps
in the mine.
No time lost when it counts
Three different steering modes optimize manoeuvrability in restricted space conditions.
Wear-resistant inner and outer material guide plates extend the
service life of the miner’s track units.

Ease of maintenance for tough operations
Maintenance is no problem at all as the entire machine offers ready access.

The air filters have been installed in an extra-high position – where the air is cleanest – and as far away as possible
from the exhaust system.
In tough mining operations, the
mechanical cutting drum drive with
three power belts stands out for its
high efficiency. Changing the belt
pulleys allows two different cutting
speeds. The nearly loss-free power
transmission guarantees highest
efficiency and top-of-the-range
daily production rates while keeping
maintenance simple. In addition,
the high-performance diesel engine
unleashes tremendous power when
it counts. An intelligent machine
management system controls the
miner’s advance rate fuel-efficiently
and in accordance with the engine
load.
All points of maintenance are ar-
ranged in a clear pattern and offer
ready access. Separate accesses
allow the cabin air filters installed
in optimal positions above the
2200 SM 3.8’s cabin to be replaced
quickly and easily. The engine
cowling can be opened hydraulically
and offers ideal access to the fully
soundproofed engine compartment.
