Mining has historically been described as a boom-and-bust industry, where fluctuations in mineral prices could result in extreme success or bankruptcy. Successful mining companies closely monitor assets/expenditures, risks, and other parameters associated with their business to best ensure their longevity. In most mineral industries, there are a few competitors that dominate the delivery of a mineral resource. As a result, technological development, along with other factors, are critical to ensure that these companies’ business remains viable and protected.

This is according to post-doctoral fellow in the Department of Geology, Dr Martin Clark.

Drone technology: better, faster, safer

He says technological development in mining generally translates to how a company can extract a resource from the ground better, faster, and safer. 

Dr Clark believes the rapid development of drone technology represents a shift in the toolbox that mining companies can employ.

“Drones can collect a great deal of data randomly over vast or small areas within hours, historically accomplished by mapping campaigns which can last months to years. Drones can also collect data in areas which are difficult and dangerous for humans to get to. These include cliff faces or rock walls that are difficult and dangerous to get close to, as well as stretches of land where dense vegetation, inaccessible terrain, and even atmospheric dangers become factors which reduce or modify the scope of exploration work,” he said. 

Expanding application of drones

Dr Clark’s work specifically focuses on expanding the applications for which drones are used. “I assess what and how good the imaging capabilities of drones are, use the imagery to generate 3-D models to drive scientific observation, and yield results which can help companies to extract resources. This initiative is called MAGIC (Multi-purpose Aerial Geological Image Classification),” he said. 



“MAGIC aims to collect geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes,” he added.

Dr Clark is not only the founder of MAGIC; he also drives multiple aspects of the initiative including education, research, and business development. 

In 2013, when he was busy with his doctorate, there was already a spark of interest in using drones to address geological questions. At that time, Dr Clark was working with remotely sensed high-resolution LiDAR imagery to better understand geological structures at the Sudbury Mining Camp in Canada. The interest became a reality in 2018, when he applied this initiative during his post-doctoral fellowship at the UFS.

Now and the future

“At present, there are no direct mining projects underway, but projects are expected to begin in 2020. Drone operation and image-analysis techniques are currently being refined for industry,” he said. 

Besides his work with drones, Dr Clark also work in the fields of structural geology, remote sensing, and geospatial data analysis.

UFS steps up measures to keep staff and students safe

The University of the Free (UFS) has extended measures to ensure the safety of its staff and students on the Bloemfontein Campus.

Part of this initiative includes the closure of the gate at Badenhorst Street in Universitas near Roosmaryn residence for traffic as from 1 October 2013. Pedestrians who can present a valid student or staff card or any form of official identification will still be allowed to access this gate. No vehicles will be allowed to pass through the Badenhorst gate after this date, though.

In addition, the pedestrian gate at the sports grounds on the western campus will also be closed from 1 October 2013.

The gate at the Agriculture Building in DF Malherbe Avenue will now be closed at 22:00 every night and over weekends, instead of being open 24 hours a day.

Closing these gates forms part of the university’s strategy to increase safety measures on the Bloemfontein Campus. Further efforts will follow to restrict access to the campus – such as the installation of an integrated electronic security systems. An intensive safety awareness campaign aimed at staff and students has also been launched and tips on how to stay safe are extensively being communicated.

Furthermore, the university will have a caravan present at major events to attract attention to security and implement a strategy to make the areas around the Bloemfontein Campus safer for students.
