Underground Lidar
Lidar sensing is used in surveys, geography, meteorology, mapping, geology and other specialist applications. Increasingly, it is used to map underground environments, such as in the mining industry. This allows miners to measure their pit dimensions accurately, providing safety assurance.
What is lidar and how does it work?

A sensor records and measures this reflected light. Combining the data from the GPS and inertial measurement unit to create a “point cloud” map in three dimensions (latitude, longitude and height). These point cloud geo-maps can then be used to create other models and maps of the area. These can offer high-resolution, with accuracy of less than a centimetre.
Can lidar ‘see’ underground?
Lidar is capable of sensing and mapping areas at night or underground, in low- light or constrained environments. Likewise, lidar can “see” through some obstructions, such as leaves or snow, and can operate effectively throughout the day or night.
However, lidar cannot penetrate the ground or solid objects.

What is lidar technology used for?
Lidar underground mapping and data sets can reveal the real-time geology of the mine, quickly and accurately. Repeated scanning can determine changes in the mine’s structure. This can inform decision making for surveyors and geologists.

Lidar use in mining
Lidar use in mining can collect data from challenged or GPS-constrained environments, such as underground or potentially unsafe sites.
The maps provide remote inspection capabilities, allowing for structural analyses, convergence monitoring or the defect inspections.
Lidar use in mining provides data to improve productivity, efficiency and safety.
