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.

First Rand Foundation contributes funding towards students with disabilities

Bursary funding for eight students with disabilities at the University of the Free State was recently approved by the First Rand Foundation. The grant of R2 497 440 will be paid over three years: R800 000 (2016/17), R824 000 (2017/18), and R873 440 (2018/19).

This grant from the First Rand Tertiary Education Fund is a result of the negotiations between the UFS Office for Institutional Advancement and the First Rand Foundation (FRF).

Qualifying students with disabilities will be encouraged to apply for bursaries according to criteria and requirements set by the First Rand Foundation. The selection process will be handled by a panel from the UFS. The Centre for Universal Access and Disability Support (CUADS) at the UFS will be instrumental in the process of identifying students with disabilities who meet the criteria and requirements for funding.

CUADS already have a system in place to support students with disabilities in their studies and during exams. Students also have access to specialised exam and test venues for alternative test and exam procedures, as well as computer facilities.

Specialised support services include an amanuensis (scribe) service during tests and exams, accommodating extra time, individual tutor sessions provided in collaboration with the Centre for Teaching and Learning, South African Sign Language interpreter coordination, provision of accessible study material, and individual disability support.

 

“The centre aims to ensure that the university increasingly becomes a universally accessible environment that is welcoming and accepting to people with diverse abilities.”

According to Martie Miranda, Head of CUADS, the centre aims to ensure that the university increasingly becomes a universally accessible environment that is welcoming and accepting to people with diverse abilities. “Therefore disability awareness training and advocacy within the UFS, and specifically among staff members, is one of our priorities,” she said.

According to Thandeka Rantsi from the FRF, the company will furthermore support students in CUADS with regards to the needs ensuing from the #feesmustfall protests. “Exactly R34 000 was approved by the FRF for 14 students towards residence and meal expenses, as well as scribe and reader assistance during additional assessments,” she said.
