Mining drones are specialized unmanned aerial vehicles (UAVs) designed to perform a variety of tasks in mining operations. These drones are equipped with advanced sensors, cameras, and other cutting-edge technology that enable them to gather data, perform surveys, and capture high-resolution images and videos from various mining environments. Mining drones can operate in harsh, remote, and potentially dangerous conditions, making them ideal for surveying both underground and open-pit mines, as well as for other critical functions like infrastructure inspections, environmental monitoring, and safety assessments.
How Drones Are Transforming the Mining Industry
Drones are transforming the mining industry by introducing a new level of automation, precision, and data-driven decision-making. They are replacing traditional methods that were costly, time-consuming, and often dangerous. By providing high-resolution imagery, real-time data analysis, and precise mapping capabilities, drones are improving the speed and accuracy of mining operations. Additionally, drones help reduce human exposure to hazardous environments, increase productivity, and enhance operational efficiency, making them an indispensable tool in modern mining.
Benefits of Drones in Mining
Drones offer several significant benefits to the mining industry. These advantages go beyond just improving safety or efficiency—they can dramatically enhance the overall operations of a mine. Let’s explore the key benefits of using drones in mining.
Enhancing Safety and Reducing Risks in Mines
Mining is inherently risky, with workers often exposed to dangerous conditions. Drones help mitigate these risks by enabling inspections and surveys to be carried out remotely. For instance, drones can access areas that are difficult or hazardous for humans to reach, such as unstable slopes or remote underground shafts. By using drones to perform tasks like monitoring mine conditions and assessing structural integrity, mines can identify potential hazards early, reducing accidents and ensuring the safety of workers.
Improving Operational Efficiency and Reducing Costs
The efficiency of mining operations can be significantly enhanced with the use of drones. For example, drones can quickly and accurately map large areas, eliminating the need for manual surveys. This not only saves time but also reduces costs associated with labor, equipment, and fuel. Additionally, drones can provide real-time data, enabling faster decision-making and optimizing mine operations. This means quicker responses to changes in the mine environment and better allocation of resources.
Environmental Monitoring with Mining Drones
Mining operations can have significant environmental impacts. Drones are crucial tools in monitoring these effects, helping mining companies ensure compliance with environmental regulations. By using drones for air quality monitoring, water management, and waste disposal, mining companies can mitigate harmful environmental effects and ensure they are meeting sustainability goals. Drones can also assist in tracking land reclamation and other restoration efforts, further contributing to environmental protection.
Applications of Drones in Mining
Drones in mining are not just limited to surveying and mapping—they are versatile tools with a wide range of applications that contribute to every phase of a mine’s life cycle.
Surveying and Mapping Underground and Open-Pit Mines
Drones equipped with advanced LiDAR sensors and high-resolution cameras are able to create detailed maps of open-pit and underground mines. In open-pit mining, drones can provide a top-down view of the pit and surrounding areas, while in underground mining, drones can navigate tight spaces and capture critical data for detailed analysis.
Stockpile Measurement and Volume Calculation
Accurate stockpile measurement is essential for inventory management and operational efficiency. Drones provide real-time, highly accurate stockpile measurements by capturing 3D models and calculating volumes. This eliminates the errors and inefficiencies associated with manual measurement methods.

Recent advancements in mining drone technology have provided mining companies with invaluable tools to improve resource management, operation planning and mining personnel safety across a wide variety of mining sites.
These improvements have been driven by advanced lidar drone technology that can be used to support mining operations by delivering a highly accurate site model thanks to lidar drone data. Lidar mining drones provide critical support for mining industry site operations in the three key areas:
- Inventory & resource management
- Monitoring and inspection
- Personnel safety
Mining Industry Applications for Lidar Drone Technology
Remotely operated equipment permits far greater data collection and hazard identification capabilities than traditional, manual methods.
Particularly helpful for surveying confined areas, lidar mining drones can capture both visual data, such as high resolution images and video, as well as geospatial information, in the form of highly accurate 3D point clouds for detailed mapping. These capabilities keep mine personnel out of harm’s way and allow for better informed decisions between planners, engineers and teams underground.
The data collected from mining drones can facilitate mining operation improvements in the following areas:
Inventory & Financial data
Rapidly generated aerial terrain models help mining industry stakeholders collect and analyze up-to-date information about all aspects of mining sites, including stockpiles, for easy and accurate volume calculations.
This data improves the accuracy of monthly or annual reconciliations, and it can also be used to help mining companies audit work performed by subcontractors.
Stockpile & Tailing Dam Management
Both tailings dams and stockpiles present significant hazards for mining personnel. Especially with stockpiles, accurately assessing a large volume of loose material is difficult and hazardous with manual methods, which is why it is one of the leading lidar drone applications.
The benefits for stockpile management are immediate, allowing mining companies to accurately assess the remaining ore in a particular site to improve financial projections and reporting, while maximizing employee safety.
Underground Monitoring & Inspection
Workers on deep underground mine sites face significant hazards and risks, including falling rocks and debris, floods, gas leaks, extreme humidity and others. By using mining drones to collect data in these environments, mining companies can protect their workers from these hazardous conditions while gaining significant improvements to operational efficiency.
Lidar & Photogrammetry for Mining Surveys
Mining drones can generate aerial terrain models and digital surface models of complex environments in a small fraction of the time and cost of traditional surveying methods.
For outdoor sites, aerial data with geospatial information permits aerial photogrammetry, which creates detailed digital surface models to assess changes over time and improve future planning. Also, in underground environments, lidar mapping can be used to create digital terrain models for low-cost surveying in short times frames.
Safety Improvements
The implementation of mining drones has improved worker safety across the mining industry by removing workers from dangerous environments.
Difficult tasks, such as highwall, crest and stope inspections, can now be assessed for safety considerations without ever having to expose a miner to the area. Similarly, blast engineering is facilitated because workers can make sure that, following a detonation, the area is safe for workers to continue mining operations.
