GROUND SUPPORT
Sandvik DS412iE extends the zero emissions
concept to the underground rock bolter class
and bolting when connected to the mains power.
Along with its direct predecessor, the new
intelligent bolter also has much in common with
the larger Sandvik DS512i in the 5 x 5 m drift size.
One example is their similar versatility in terms of
bolting systems: Sandvik DS512i and Sandvik
DS412iE can handle a wide range of bolt types and
lengths, including a combination of automatic
cement mixer and automatic resin injection on the
same bolter.
The new Sandvik DS412iE will effectively
complete Sandvik Mining and Rock Technology’s
rock support drill range for the 4 x 4 m class,
updating its entire product range to the latest i-
standard of connectivity and automation
capabilities, the company said. Additionally, the
Sandvik DS412iE will be the supplier’s first
battery-powered rock bolter.

Training specific to rock stability
Education and training specific to deep mining
conditions is something that has recently come
under the spotlight in Europe. A consortium of
leading mining universities and mining companies
has designed a dedicated training programme for
mining professionals. ‘SafeDeepMining’ is funded
by EIT RawMaterials and aims to address the
shortage of highly trained rock engineering
personnel for deep mines that can deal effectively
with the rock pressure problems jeopardising the
extraction of deep mineral deposits.
Rock stability is one of the major challenges in
European underground mining as the industry
increasingly moves to extract ores from deeper
levels. Experience shows, that despite progress
made in rock mechanics and numerical modelling,
there is still a considerable shortfall as far as
application of rock mechanics principles in mine
design and mining operations is concerned.
There are numerous examples of rock pressure
related problems that have occurred which could
have been avoided with good rock engineering.
During 2019 alone, a number of seismic events in
deep mines in Europe and beyond damaged
infrastructure and caused fatalities.
During the past 50 years the majority of statecontrolled
mining ventures have been closed and
many of the leading mining research organisations
have been either shut down or their activities
heavily reduced. Many mining departments and
programmes at European universities have been
closed. This has resulted in the loss of skilled and
experienced industry and university personnel in
the field of rock mechanics.
There has also been a loss of expertise and
infrastructure in the mining industry, government
agencies concerned with supervision of mining
activities, research organisations and universities.
All of this means that new developments in rock
engineering are not being applied or are being
done so incompletely.
The stated objective of SafeDeepMining is to
educate mining engineers, authority staff and
personnel in consulting and at universities in state
of the art rock engineering to assist European
mining industry in dealing with rock pressure
