Uphole Drill Hole Deviation Device

The Boretrak360º borehole deviation measurement system is a simple-to-use, gyro-based system for measuring the deviation of uphole and horizontallly drilled boreholes. This specific system is used for underground operations to ensure safety and security for mining personnel. Paired with the Carlson Boretrak® software this system provides an all in one workhorse to peace of mind underground.

Gyro-Based Solution

The Boretrak360º utilizes a miniature inertial measurement unit (IMU) which contains a triaxial accelerometer, magnetometer, and gyro. Prior to deployment, the probe is calibrated against a known orientation on a supplied jig. This establishes a starting reference azimuth for the gyro. The gyro provides the Boretrak3 with an accurate, live heading which is tracked as the probe is deployed along the borehole.

Deployment Methods / Accessories

Uphole and Horizontal deployments can be achieved by using the traditional Boretrak® rods along with a semirigid cable.

Display & Output Options

Data from surveyed holes is displayed in 3D graphical mode, 2D schematic mode, or tabular formats. Data can be transferred to Carlson Boretrak on desktop for analysis. Export formats include DRL for BlastOPS, DXF, and CSV. Reports include plan, front, side, and 3D views with tabular readings.

Benefits

Benefits — Summary

Measures boreholes at any inclination; detects deviation from design; used in underground mines, quarries, open-pit operations, and civil works.

Safety & Compliance

Enables user to compare vertically drilled holes to their as-built model.

Efficiency & Productivity

Lighterweight solution makes it even easier for one person to deploy and survey boreholes with the probe.

Ruggedness / Environmental Suitability

Designed for lightweight vertical underground deployments, without sacrificing the same dependablity that the Boretrak® is known for.
