Borehole surveys

In order to verify parameters such as hole angle, hole direction and hole depth, we introduce a system designed for effective and exact borehole surveying. Optional integration of GNSS and borehole survey data into existing quarry face surveys rounds out the documentation for each blasting project.

Standard borehole surveys

Easy to use!

The Blasthole Probe Mk3 was designed for fast and precise verification of boreholes. Incorrect hole angles, incorrect hole depths and deviations from the target hole path often result in serious problems during blasting. The Pulsar Mk3 system is an efficient and therefore affordable option for achieving bore precision—and implementing corresponding countermeasures based on the results.
Using the data from the integrated inclination sensor and the digital compass, deviations of the hole from the target are calculated at user-defined depth intervals. Detailed reports on the borehole path can be created right in the field.
Deeper data analysis using QuarryX is possible by combining the data from the borehole survey with the 3D quarry face model from the Pulsar 3D FastScan Profiler. This enables exact and comprehensive blast planning for improved safety and efficiency with every blast.

Small-Diameter Surveying

The solution for small hole diameters!

Micro Probe Mk3 is the smaller version of the standard blasthole probe (Blasthole Probe Mk3). It can check even narrow boreholes from 35 mm diameter.
The Pulsar Micro Probe records the actual borehole path and possible deviations from target. This enables easy minimization of risks related to incorrect hole angles and depths.
Integration of the borehole survey data into existing quarry face surveys enables complete documentation of each blasting project and reduces the risk of fly-rock to a minimum.
