How Mine Drones Are Improving Safety and Optimizing Mining

6 Ways Mine Drones Are Being Used

Mine drones have become essential tools in both underground and surface mining operations. As drone technology continues to evolve rapidly, the potential for integrating these devices into mining processes is expanding endlessly.


What Is a Mine Drone?

A mine drone is specifically designed or adapted for mining applications such as stockpile measurement, surveying, mapping, and inspections, including ultrasonic thickness testing. Mining is inherently dangerous, with unpredictable working conditions that can change at any moment. Both underground and surface mining present unique challenges and risks.

While mine drones won't eliminate all dangers, they can collect data from areas where humans cannot go. A key difference between mine drones and consumer drones is their ability to operate without GPS, which is often unavailable in mining environments.

The mining industry has quickly adopted drone technology due to its ability to improve data collection, enhance safety, and reduce operational costs. Here are six ways drones are being used in mining:

1. Volumetric Monitoring

Volumetric measurement involves calculating how much material remains in stockpiles of overburden, ore, or other mining materials. Due to the large size of these stockpiles, manual methods are inefficient and inaccurate.

Drones allow for quick and cost-effective volume data collection. Using advanced software, drone data can be processed into 3D models that track changes over time. These models help in estimating backfill needs and monitoring excavation progress.

2. Identifying Hazards

Cracked rocks, gas leaks, dust explosions, and hazardous underground conditions pose significant risks. By using UAVs, surveyors can reduce these risks by removing people from dangerous inspection tasks.

In surface mining, drones monitor stockpile stability, while in underground mines, they navigate dusty and rocky areas to detect blockages and create 3D models of geological features.

3. Drilling and Blasting Assessment

Drones generate 3D models that help analyze the impact of drilling and blasting. These models support future decision-making, assess blasting effectiveness, and provide remote safety checks before human entry.

4. Mine Monitoring and Planning

Drones play a crucial role in haulage road design, equipment inspection, worksite security, and environmental monitoring. They help maintain infrastructure, ensure safety, and protect the environment by monitoring tailings dams and other critical systems.

5. Mine Development and Exploration

Drones are invaluable for exploring inaccessible areas, reducing risks for miners, and collecting critical data. The Elios 3 is particularly suited for confined underground spaces with poor visibility and air quality.

6. Processing Plant Inspections

Drones inspect processing plant machinery without disrupting operations. They check wear and tear, measure thickness, and monitor temperatures, ensuring efficient and safe production.

The Benefits of Drones in Mining

As drone technology advances, the benefits of using UAVs in mining continue to grow. Drones improve safety, reduce costs, and optimize efficiency through aerial data collection, frequent inspections, and remote monitoring.

Some key advantages include faster data gathering, reduced human risk, improved accuracy, and enhanced environmental protection. Drones like the Elios 3 offer unmatched performance in challenging mining environments.

Mining Drone Case Studies

Flyability Elios 2 — Inspection

Application: High-Altitude Underground Mining Inspection

Mission: Demonstrate the ability of the Elios 2 to cut down costs and improve safety in a high-altitude oxygen-depleted mine environment.

Results: The Volcan team conducted 40 flights with the Elios 2 inspecting chimneys, ore passes, ventilation tunnels, and stopes. 3D maps of the various flights were created using Pix4D mapping software. All planned inspections were a success, and the drone met all expectations.

Mine Drone Significance: The Elios 2 was able to operate where no other drone could. Many mines are located in high-altitude locations where regular drone use is not feasible. By using a drone to navigate the mine, miners can let the Elios 2 do the dirty work while saving time and money.

Wingtra— Survey

Application: Mine / Quarry Monitoring and Operational Planning

Mission: Reduce operating expenses of terrestrial and manned airplane surveys by integrating a fixed-wing mine drone platform into surveying operations.

Results: The Jellinbah Group found that utilizing the WingtraOne drone resulted in a significant decline in operational expenses and time. The fixed-wing platform also alleviated the inefficiencies of quadcopters that the company had tested previously. The ROI is immediately noticed as Jellinbah can now conduct on-demand surveys compared to the time-consuming logistics of manned surveying.

Mine Drone Significance: Large mining sites are no longer limited to multirotor drones that are inefficient and impractical. The vertical takeoff and landing feature is also a game-changer and allows surveys to be conducted anywhere.

SenseFly— Survey

Application: Quarry Monitoring and Operational Planning

Mission: Survey the largest limestone quarry in a day. The quarry measures a whopping 13.7 km², and it usually takes two months to survey.

Results: The quarry was split into three large segments; upper, middle, and lower. Four drone pilots were divided into two teams to cover the site efficiently. The team decided to use senseFly's eBeeX fixed-wing drone. The eBeeX's ability to fly for longer durations made it the perfect choice. Within a few hours, the drone took over 6,000 high-resolution images that were converted into orthomosaic images and 3D models.

Mine Drone Significance: Surveying a site of this size used to take up to 2 months. Not only does that cause delays, but it also increases the risks for surveyors. The benefit of using mine drones is quick turnaround time, resulting in a safer and more cost-effective operation.

DJI— Survey

Application: Quarry Drilling and Blasting

Mission: To identify how a customized drone solution for mining can deliver the safest, controlled, and cost-efficient execution of a scheduled blast operation in a quarry mine.

Results: The customized DJI Matrice 300 RTK drone and Zenmuse H20t cameras functioned well regarding control and operational decision-making.

Here are some areas the drone excelled in:

  • Checking for compliance with minimum withdrawal distances

  • Correcting the locations of lookouts.

  • Replacement of the inspection vehicle bypass

  • Observation of blind spots

  • Overall survey and recording of mass explosion

Mine Drone Significance: The purpose of using drones in mining is to mix the miners' knowledge with the drone's digital intelligence. An operation becomes safer and less expensive to run overtime by having actionable data.

DroneDeploy— Stockpile Measurement

Application: Stockpile Volumetry

Mission: Improve the accuracy of volumetric stockpile measurements to increase safety and reduce expenses for Granite Construction.

Results: Using DroneDeploy, the company achieved accuracy comparable to traditional methods in a fraction of the time. For this site, all volume calculations were within 1% of alternatives.

Mine Drone Significance: Using aerial volumetric software is faster, safer, and half the cost of the traditional ground-based stockpile calculations.
