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

6 //7

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.

10 //11

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.
