Using Drones to Assess Inaccessible or Dangerous Areas in Mining

Using Drones to Assess Inaccessible or Dangerous Areas in Mining

The mining industry has long been fraught with safety risks, with workers often required to navigate hazardous environments to perform essential site assessments and monitoring tasks. From unstable high walls to toxic uranium ponds, inaccessible areas in mining present grave dangers to human health and safety. As technology advances, drones have emerged as powerful tools that allow mining companies to survey these perilous zones safely and effectively.

The Challenges of Surveying Hazardous Zones

Mining operations involve many inherently dangerous areas that are vital for production but can be extremely hazardous to human life. For example, high walls in open-pit mines pose a risk of collapse, while tailings dams, which store mining waste, have the potential to leak toxic materials. Underground sites, especially in uranium and coal mines, contain high levels of toxic gases and may be prone to cave-ins or explosions. Surveying these areas traditionally requires workers to put themselves in potentially life-threatening situations.

These dangers underscore the need for alternative methods to assess and monitor hazardous zones. Traditional practices may require workers to navigate unstable ground or come into contact with toxic substances, making the call for safer, more efficient solutions clear.

How Drones Make a Difference

Drones have proven their worth as essential tools in high-risk industries like mining. By using drones to access hazardous or inaccessible areas, mining companies can collect valuable data without placing workers in harm’s way. Drones can be deployed to fly over, around, and even within mine sites that are too dangerous for human access. This capability not only enhances safety but also improves efficiency by reducing the need for manual inspections and measurements in unsafe zones.

Equipped with advanced sensors, drones can capture high-resolution images and video footage, providing valuable insights into the condition of mining sites. This approach minimizes the need for human presence in dangerous areas and allows workers to monitor site conditions from a safe distance.

Drones designed for mining applications often come with specialized technologies tailored to assess unsafe areas accurately. Among the most important are multispectral sensors, LiDAR, and thermal imaging. Here’s how these technologies contribute to safer operations:

  1. Multispectral Sensors: These sensors can detect vegetation health, which can be an indicator of environmental contamination or instability in certain areas. They are especially useful for monitoring tailings dams and identifying any signs of leakage or erosion.

  2. LiDAR: LiDAR technology generates precise, three-dimensional maps of the terrain, including the surfaces of high walls and underground cavities. This capability helps to identify structural issues in high-risk areas, providing mining companies with essential information for maintaining stability and avoiding accidents.

  3. Thermal Imaging: By detecting temperature variations, thermal cameras can identify areas that might be emitting heat due to chemical reactions or machinery malfunction. This is particularly valuable for detecting potential fire hazards or identifying areas with abnormal heat signatures, which could signify gas leaks or electrical failures.

With these technologies integrated into their drone fleets, mining companies can gain comprehensive data on inaccessible areas, enabling proactive maintenance and reducing the risk of dangerous incidents.

Case Study: Drones in Hazardous Mining Environments

DJI's drones are revolutionizing safety and data accuracy in mining operations. In controlled blast zones, these drones provide real-time data and oversight, minimizing risks to personnel and equipment.

The BHP Mitsubishi Alliance in Australia uses DJI’s M350 RTK for 3D spatial mapping, improving safety and precision in hazardous areas. Features like arm lock sensors and high-resolution cameras enhance accuracy, detecting potential issues early.

Ferrexpo AG in Ukraine employs the M300 RTK for perimeter monitoring during quarry explosions, using advanced camera capabilities to eliminate blind spots and maintain secure perimeters. The drones, equipped with high-zoom and thermal cameras, effectively monitor, tag, and document activities, aiding in compliance and safety. Overall, DJI’s drone solutions support smarter mining, integrating safety features with cost-effective, efficient monitoring.

Conclusion: Integrating Drones for Safer Site Assessments

As mining companies face ongoing challenges in managing dangerous and inaccessible areas, the adoption of drones offers a forward-looking solution for safer and more efficient site assessments. By integrating drone technology, mining companies can protect their workers, enhance operational efficiency, and gather comprehensive data that traditional methods cannot easily provide. Moving forward, drones will likely play an even more central role in ensuring that mining operations can be conducted without compromising the safety of those involved.

For mining companies that value the safety and well-being of their workforce, adopting drones is not just a technological upgrade—it’s a necessity.
