How LiDAR Scanning Is Replacing Traditional Surveying in Large-Scale Mine Sites
Airborne LiDAR delivers sub-metric accuracy, with no exposed personnel, in one third of the time. We analyze the real impact in Chilean mining operations.
For decades, topographic surveys in mining depended on human teams stationed in hazardous zones. A surveyor with a total station, full working days in active terrain, and then additional days of processing to obtain a usable model.
The operational reality is stark: in an active open pit, the surveyor works while 300-tonne trucks circulate meters away. Every survey is an exposure to risk.
The shift LiDAR enables
LiDAR (Light Detection and Ranging) emits laser pulses and measures the return time to build a three-dimensional point cloud. Mounted on an autonomous drone, it can map hundreds of hectares with a density of more than one million points per square meter, with accuracy of ±2 centimeters.
The result: a certifiable digital terrain model generated in minutes, not days — and without anyone setting foot in the active zone.
In a pilot operation conducted in Chile’s Atacama Region in 2024, the SBY ICARUS system surveyed 850 hectares of active open pit in 4 hours. The traditional method with a total station would have required 3 days with a 6-person team on site. The difference isn’t incremental — it’s structural.
Impact on decision-making
The most underestimated factor of autonomous LiDAR isn’t speed: it’s frequency. With traditional surveying, a mine manager receives volumetric data once a week, at best. With ICARUS, they can have an updated survey of the previous shift before the morning briefing.
This frequency completely changes the decision-making cycle:
- Daily production control: actual extracted tonnage vs. planned is known every shift, not every week
- Early reconciliation: discrepancies between measured and declared production are detected before they accumulate
- Blast planning: the updated topographic model allows blast pattern planning with exact geometry
At our current operations, the production manager receives the previous shift’s volume report before 7:00 AM. The team makes decisions with same-day information, not last week’s.
The regulatory argument
Chilean regulations require that slope stability studies include certified topography. Historically, this meant hiring an external surveyor for every monitoring event.
SBY ICARUS automatically generates a digitally signed report with the geometric parameters of the slope, compatible with the formats required by Chile’s National Geology and Mining Service (SERNAGEOMIN). Time spent on regulatory reporting is reduced by 90%.
The economic argument
The cost of a traditional survey in a large open pit ranges from USD 8,000 to USD 25,000 depending on complexity and the firm hired. With ICARUS, the cost of a complete survey falls to a fraction of that, and can be run daily.
ROI is easy to calculate: if data frequency allows detecting a production loss of 5,000 tonnes per shift that previously went unnoticed for a week, the recovered value far exceeds the annual platform cost.
The real question
The question isn’t whether LiDAR is more accurate or faster than traditional surveying — in both dimensions the advantage is clear. The question is how many suboptimal decisions are being made today in your operation due to lack of updated data.
In large-scale mining, the difference between deciding with yesterday’s data and last week’s data is measured in tonnes and in people’s safety. Autonomous LiDAR turns that difference into a computable operational advantage.
