The Face Master 1.7 comes
in different configurations
depending on the market
demand, with the recently
launched Face Master 1.7K,
for KGHM Polish Copper Mine,
boasting a spacious, air
conditioned, closed cab with
excellent visibility and
ergonomics, GHH said. This provides for high
level operator comfort and associated
performance. The FM 1.7K comes equipped with
a more advanced feeder guiding system, where
the on-board computer helps the operator
execute desired drilling patterns, as well as
generate 24-hour reports showing the quantity of
drilled holes, time of drilling as well as
comparison of planned work to actual results.
MM, together with Fletcher, provides roof
bolters, with a rotary dry drilling system with
dust collection for ultra-low and low seam
mining. The Roof Master 1.4 mechanised roof
bolter is designed for bolting hanging and side
walls at a minimum height of 1.6 m with a
maximum reach of 3 m and a bolt length of 1.6 m.
The Roof Master 1.7 is also a mechanised roof
bolter designed to operate within 1.9 m heights.
It has a maximum reach of 4.5 m and is designed
to install both mechanical and resin bolts at
lengths of 1.6 m, 1.8 m and 2.6 m by a single
operator. For narrow vein applications, MM has
the highly productive, low tramming height Face
Master 2.1 used for face drilling as well as long-
hole drilling. This has a quick reset of the feeder

which certainly sets us apart from

More MUKIs
Resemin’s MUKI family of
mechanised narrow vein
equipment has continued to
expand in recent years, and CEO
James Valenzuela told IM the
position and an additional cylinder allowing for
accurate drilling of the vein deposit.
“GHH machines enable the lowest cost per
tonne production with highest performance
capabilities,” the company said. Its machines are
robust, reliable, easy to maintain, simple to operate,
and designed with safety in mind, GHH added.
“Our machines are created to work in narrow
vein applications from the deep level gold mines
in Australia to the high altitude mines in Latin
America, as well as in the low profile chrome and
platinum group elements from the South African
Bushveld Complex through to the Zimbabwean
Great Dyke, in addition to the copper orebodies
in Poland and the potash and salt mines across
Germany,” GHH said,
“We pride ourselves in the ability to constantly
develop safe products that are moulded to the
ever-changing customer needs, incorporating
custom designed end user specific options, to
make each of our underground mining products
more fit-for-purpose than before, to suit specific
mining operations,” the company concluded.
“GHH Group is not only well known for its rock
solid, robust low profile and narrow vein product
company is preparing to add more
products to the offering.
“In addition to our versions of MUKI Front
Face, long hole and MUKI Bolter, it is very likely
that we will develop a scaler for narrow veins,”
Valenzuela said.
The Resemin chief said the company, since
launch last year, has sold three MUKI Bolters to
local South America customers, but sees a much
wider market ahead.
“The miners, each time, are asking for more
safety in the bolting process,” he said. This is a
departure from the Australian roof bolting
method using a MUKI Front Face, equipped with
Telescopic Feed 6-10, miners were previously
asking for, according to Valenzuela.
“This method (Australian roof bolting) is still
the dominant one, but we have seen a growing
demand for mechanised roof bolting processes in
narrow vein mining,” he said.
In addition to the recently launched MUKI
Bolter, Resemin also released, last year, the
narrowest ANFO/emulsion charger on the
market, he said. The AC11 is just 1.3 m wide, with
Valenzuela saying the use of emulsion can
reduce nitrous gases produced by blasting and
make the mine cleaner.
Poland’s KGHM Zanam showcased its new LKP-1701 underground LHD at Bauma 2019, in Munich, which is the largest and most advanced machine to
date in its range and undoubtedly one of the largest available low profile LHD machines globally. The machine is 11,500 mm long, 3,335 mm wide and
2,370 mm high with a 47 t operating weight unloaded, front axle load of 21.5 t and rear axle load of 25.5 t and a standard bucket capacity of 9.5 m 3 .
Tramming capacity is 172 kN and edge of bucket breakout force is 220 kN. The machine can lift and dump in 8.5 seconds and do a full turn in 5.5 seconds
with an internal turn radius of 3,450 mm and external 7,750 mm. Fourth gear speed is up to 27 km/h. It has a Deutz 12.0V6 Stage IV engine with 330 kW
at 2,100 rpm. KHGM Zanam says its 1700 series LHDs are noted for high bucket capacity and lifting capacity along with their low profile
