BLAST DESIGN - geo-konzept GmbH

Blast design
GPS - surveying in mining
Task
The 3D measuring of a rockface (e.g. with the Pulsar 3D FastScan profiler) is a very quick and easy way to
produce an accurate 3D model of the blast area. This 3D model supports planning a safe and efficient blast.
In the same way, the complexity of a blast is growing and the whole blast pattern gets more and more difficult.
Furthermore, the 3D scan only shows the rockface and not the upper floor, which is the start point for
the blastholes. If the hole top deviates from its planned position, it is possible, that the actual Z-level of the
drilled blasthole changes too. This may cause a false hole depth.
Solution
For a more efficient staking-out of blast patterns and a more accurate planning, geo-konzept GmbH developed
the QuarryPocket GPS software. By using coordinates, calculated by the GNSS receiver, the software
leads the user to the planned collar. A constant control of the coordinates and quality parameters guarantees
highest accuracy and safety.

Blast Design
integrated workflow
After recording the 3D-model of the rockface with
the laser scanner, the blast pattern is planned in the
QuarryX software. The calculated coordinates for the
collars are transferred to the GNSS-system. Afterwards
the points can be staked out by using the
QuarryPocket GPS module. During the staking-out
of the drilling positions the measured coordinates are
recorded and subsequently transferred to the
QuarryX software. Now, the actual blasthole positions
serve for calculating the exact drilling depths.

safe and efficient blast
Drill Rig Guidance System RiGuide
Based on 3D-laserscanning data geo-konzepts
blastdesign software QuarryX allows the user to
design safe and efficient blasts. To transfer the designed
holepositions and parameters to your bench,
geo-konzept offers the GPS/GNSS based Drill Rig
Guidance System RiGuide. RiGuide is an easy and
practical retrofit solution for drill rigs of service providers
and quarry owners. The complete blast design
can be transfered via USB to the terminal on the
drill rig. With it´s built in navigation functionality, the
system guides the user to the planned hole positions
with an accuracy of 2 cm. With this solution a
manual stake out with measuring tape and spray
colour is no longer required. The system also assures
that drilling is accomplished according to the
designed parameters, like drillangle, azimuth and
holedepth.
