Drones for Mining in South Africa: An Interview with Hendrik Grobler of the University of Johannesburg
In this interview, we had the opportunity to speak with Associate Professor Grobler about the integration of drones in South African mining operations, particularly focusing on their role in enhancing safety, efficiency, and data collection. Drones are proving to be invaluable tools for monitoring surface changes and conducting inspections in challenging underground environments.
My journey in mining began in 1991 when I graduated with a degree in mine surveying from the University of Johannesburg. After obtaining my Government Certificate of Competency in 1994, I worked in various mines specializing in gold, nickel, and platinum extraction over the following thirteen years. In 2007, I transitioned into academia, returning to teach at the University of Johannesburg in the same department where I initially trained.
The Mining Engineering and Mine Surveying Department at the University of Johannesburg is celebrating its centenary in 2026. It offers undergraduate degrees in mining engineering and mine surveying, along with postgraduate programs. Annually, we educate approximately 600 students, many of whom are already employed in the mining sector prior to enrolling or join the workforce upon graduation.
Our department boasts unique training facilities, including a simulation mine constructed several years ago. This facility simulates a real mine environment, allowing students to gain practical experience without venturing into hazardous sites daily. Additionally, we utilize advanced technologies such as Boston Dynamics’ Spot robot and Flyability’s Elios 3 for testing and demonstrations.
Drones play a crucial role in modern mining practices. They assist in surveying vast landscapes efficiently and safely, reducing risks associated with traditional methods. Inspections conducted by drones provide critical insights into unstable areas and aid in identifying potential hazards.
Safety remains paramount in our efforts to minimize risks. Recently, tragic incidents involving rescue missions underscored the necessity for safer alternatives. Utilizing drones can prevent unnecessary human exposure to dangerous conditions.
However, there are challenges related to compliance and adequate training among users. Proper licensing and sufficient preparation are essential for safe drone operation in industrial settings.
Flyability’s Elios 3 stands out due to its robust design and enhanced stability features, making it ideal for confined space inspections. Its ability to carry LiDAR sensors further expands its utility by enabling detailed mapping even under poor visibility conditions common in South African mines.
Looking ahead, widespread acceptance of drone technology across all major mining enterprises seems promising. Each operation could benefit significantly from maintaining dedicated drone fleets capable of frequent mapping tasks.
This conversation highlights how transformative drones can be in reshaping traditional mining practices towards greater sustainability and worker protection.
