TECHNICAL DATA
*Available only with MRH6 rotary head
uncoupling, feed auto aligning, and feed auto
positioning into a single efficient sequence.
These capabilities can be further upgraded with
more advanced modules such as single-rig or fleet
remote control systems by Automine ® Surface Drilling.
Motilal continues that from an operator perspective,
operators have taken well to Sandvik’s drilling product
range, and she states with conviction, “Once they
become accustomed to using the product, it becomes
their equipment of choice.” The new-generation
machine is appealing to experienced operators and
youngsters accustomed to the use of joysticks as used
on PlayStations.
In addition, all Sandvik’s automation platforms have
a similar set-up; therefore, operating various pieces
of equipment in the range is seamless, making the
training of operators on newer equipment easy,
she adds.

Pipe sizes range from 89 to 140 millimetres,
depending on the size of the hammer. The maximum
hole depth is 53.6 metres when utilising the carousel
option with pipe sizes from 89 to 114mm. The capacity
range of 403kW Tier 3 CAT C15 diesel engine and
reliable compressor is adequate for high-pressure
drilling with 4-6.5-inch DTH hammer sizes.
According to Motilal, the intelligent drill rig with full
cycle one-hole drilling automatics can be equipped
with a wireless data transfer option, which offers the
possibility to download and transfer drill patterns from
the mine to the machine and back. Alternatively, the
information can be extracted and saved onto a USB.
“This offers the client a platform to access
information from various locations in real-time, which
assists with ensuring accuracy as related to size,
depth, and drill hole interval. Editing tools also make it
possible to design each hole individually. In essence, a
client can, with just a click of a button, accurately drill
as per requirement,” says Motilal. ■
