3D Mapping

The DB4™ is equipped with our revolutionary SafeScanner™. With the SafeScanner™ in place, the DB4™ is able to internally produce 3D models of the flight environment with little to no shadowing. A default PTS file is produced, and alternative file formats [LAS, DFX, etc) are available to export. 3D model production takes between 10 and 25 minutes post flight and can be retrieved using a standard USB. This allows the operator to review results immediately underground or transmit them to surface for analysis and support.

HD Video

The DB4™ provides options to capture high definition video and images that can be viewed immediately and provide critical information regarding the safety of the environment, the condition of the face and support more effective planning and development.

Live Render

This is the real-time visualization of the submap data model during real-time scanning. This is a 3D projection of the mapping data model representing where the mapping system believes objects are in the environment. This visualization allows the user to observe the quality of the mapping session and potential gaps in mapping coverage.

Pilot Assist

The DB4™ comes equipped with a pilot assist configuration. This allows for the operator to ensure they are always in complete control of the drone at all times, while at the same time providing key assistance in accessing tight spaces. Using SafeSight’s semi-autonomous hover and obstacle avoidance features, operators can access close proximity flights that allow access into narrow openings unachievable by other underground drones. These features create ease-of-use while ensuring the operator is always in complete control of the technology.

FAQ

Know More About Underground Mining Drones​

Underground drones are specialized unmanned aerial vehicles (UAVs) designed for use in confined and hazardous underground environments such as mines, tunnels, and caves. These drones are equipped with advanced technologies to perform tasks like inspection, mapping, data collection, and emergency response without exposing humans to risks.

Here are the 5 Underground drones used for:-

  1. Mine Safety Inspections: Identifying structural weaknesses, monitoring air quality, and inspecting equipment.
  2. Mapping and Surveying: Creating accurate 3D models of underground structures for planning and operations.
  3. Emergency Response: Locating trapped workers or assessing damage after accidents without putting rescue teams in danger.
  4. Environmental Monitoring: Detecting hazardous gases, checking water levels, and monitoring ecological conditions.
  5. Infrastructure Maintenance: Inspecting tunnels, pipelines, and underground utilities for wear and tear.

Key Features of Underground Drones

  1. Compact and Durable Design: Designed to navigate narrow passages and withstand challenging conditions like dust, humidity, and temperature variations.
  2. Advanced Navigation Systems: Equipped with GPS-free navigation using LiDAR, SLAM (Simultaneous Localization and Mapping), or optical sensors for precise movement in GPS-denied environments.
  3. High-Quality Cameras: Include thermal imaging and high-resolution cameras for inspection, 3D modeling, and visualization.
  4. Obstacle Avoidance: Advanced sensors to detect and avoid obstacles in tight spaces.
  5. Data Collection: Capable of collecting and processing data for real-time analysis or later use, such as creating 3D maps.
  6. Safety Enhancements: Can assist in emergency situations, identifying hazards like gas leaks, unstable structures, or blocked pathways.

Underground mining drones rely on technologies like LiDAR (Light Detection and Ranging), SLAM (Simultaneous Localization and Mapping), and other optical and inertial sensors. These systems enable precise navigation by creating real-time maps of their surroundings.

Most underground drones can operate in both modes. Manual operation allows precise control, while autonomous modes use pre-programmed flight paths and AI-based navigation to perform tasks independently.

Yes, some advanced underground drones are designed to carry small payloads like sensors, sampling tools, or communication devices, making them versatile for various tasks.

Emergency response drones are used to locate survivors, assess damage, deliver medical supplies, monitor hazardous areas, and support communication in disaster zones. Their speed and ability to operate in unsafe or inaccessible areas make them vital for saving lives and improving response efficiency.

Underground drones can gather:

  • 3D spatial data for mapping and modeling.
  • Visual data through high-resolution or thermal cameras.
  • Air quality measurements, including gas detection.
  • Structural analysis using LiDAR or other sensors.

Battery life varies depending on the drone model and its features, typically ranging from 20 minutes to over an hour. Many drones offer swappable batteries to extend operational time.

Weight Range of Underground Drones

  • Small Drones (1–5 kg):Usage: Primarily used for lightweight tasks such as basic inspections, visual data collection, and simple mapping.
    Examples: Compact models designed for narrow spaces and easy portability.
  • Medium Drones (5–15 kg):Usage: Used for more advanced tasks like 3D mapping, LiDAR scanning, and carrying small payloads (e.g., sensors or cameras).
    Features: These drones often include advanced navigation systems and higher endurance for extended operations.
  • Large Drones (15–25+ kg):Usage: Heavy-duty models built for complex tasks, such as carrying multiple sensors or specialized equipment for air quality monitoring or sample collection.
    Features: Typically more robust and capable of operating for longer durations in challenging underground environments.
