Northern Survey Supply - Mine Surveying Equipment and Monitoring Systems

Mining represents the most rugged use of equipment and applications in the engineering market place. Northern Survey Supply provides reliable, accurate and innovative survey equipment solutions. Integrating technology to increase safety, accuracy and efficiency is at the core of our business. Together with our partners and customers, we combine safety and efficiency in all our products. Integrating surveying equipment is what we sell, provide training for and support.

Surveying interface system

Leica fieldPro is a remarkable surveying interface that combines AutoCAD’s 3D CAD system with Leica’s robotic primless total stations for use at the underground working face. Leica fieldPro offers the mining surveyor the ability to work directly on the 3D mine designs while superimposing measurement data on the design layout. The actual over and under break is clearly displayed and provides a host of mining specific layout and markup functions for underground surveying.

Robotic surveying instruments

Leica’s robotic instruments can also be used for cavity monitoring surveying (CMS) using wireless communication. The instrument is fastened to a boom and controlled wirelessly in the open stope, keeping the surveyor in a safe environment while the CMS is being performed. One instrument performs surveying tasks, mine layouts and cavity monitoring surveys.

3D mine design and data measurement software

Leica fieldPro is the latest integration of mining technology offering immediate return on investment. It has the following features:

• Face mapping can be easily be done by one person
• Data is more accurate
• Capture and layout of grade lines
• Section and face profile viewing
• Mine surveys are updated daily
• Less rework (benching / slashing)

Wall mount prisms

If you're still hanging plumb bobs and string, surveying doesn't have to be that difficult. Wall mount prisms from Northern Survey Supply allow all surveyors to secure control points at a comfortable and accessible height, while increasing accuracy and speed of use. All grade lines and azimuth are easily established using proven calculation techniques in a fraction of the time, reducing down time for your mining crews.

Tunnel measuring instrumentation

Mechanized mining techniques have created the need for more efficient underground navigation with reduced overhead costs. Tunnels and drifts underground have increased in size to allow for today's large mechanized machinery, making it more difficult for surveyors to reach up and position their control points in the back or ceilings.

Using wall mount prisms and utilizing common coordinate geometry techniques frees up the surveyor to place control wherever required at chest height. This simple but revolutionary idea provides surveyors with safety, speed and accuracy when marking up drifts for line, grade, tope and all other mining-related surveying tasks.

Tunnel measuring / wall mount prism system

The tunnel measuring system consists of ⅜in stainless-steel sleeves, which are counter-sunk into the drift wall, leaving nothing to be struck or bent. The prism adaptors are inserted into the sleeve and have a standard Leica prism mount that adapts to all Leica prisms. The adaptor shoulder rests on the sleeve, providing excellent repeatability. The only thing left behind in the wall is the stainless-steel sleeve. The system is installed using the following procedure:

• Drill a ⅜in x 4in hole in the drift wall
• Slide the stainless-steel sleeve onto the setter tool (pounder)
• Friction-fit the sleeve (slightly counter sunk)
• Insert the stainless-steel adaptor
• Attach the Leica prism

Laser distance meters

Leica DISTO is the innovative hand-held laser meter for fast and easy distance measurements of length, squares and volumes with the press of a button. Save time and money and emphasise your competence with modern measuring methods.

The Leica DISTO D8 is the most versatile laser distance meter in the world. Equipped with a digital Pointfinder, high-resolution 2.4in colour display, 360° tilt sensor and Bluetooth® technology, the Leica DISTO D8 is a real world-first and offers completely new measuring options.

Slope and structure monitoring systems

Whether you monitor the movement of a volcanic slope, or measure, analyse and manage the structures of natural or man-made objects, the monitoring systems by Leica Geosystems provide the right solution for every application.

Automatic deformation monitoring system

Each monitoring project has specific measurement and accuracy requirements. The Leica GeoMoS software provides a highly flexible automatic deformation monitoring system that is able to combine geodetic, geotechnical and meteorological sensors to match the needs of your monitoring project.

Precise structural movement monitoring system

Wherever you need the most precise and reliable information on structural movement, Leica GeoMoS Adjustment allows you to make informed decisions based on statistically optimized and validated data.
