Highlights

Extraction process

Rock engineering assistance

Our digital rock engineering assistant platform helps mining practitioners to master and perform selected rock engineering functions with greater accuracy and efficiency. It provides a one-stop database for different types of data gathered, in a format that allows for filtering, display of data on a mine plan and assistance with data analysis. It also provides the option to export search data. The platform is compatible with standard computers and mobile devices, streamlining data collection, analysis and storage. It automates key portions of selected tasks, executes simple calculations and enriches user learning by embedding step‑by‑step explanations of processes, ensuring consistent and reliable results. Currently at technology demonstrator phase, a beta version will be undergoing operational stress‑testing at mining sites in South Africa, whereafter it will be available for licensing.

Testing body cooling garments to keep mine rescue teams safe underground

The CSIR supported Sibanye-Stillwater Ltd in assessing whether a body cooling garment could help keep rescue workers maintain heat tolerance for longer than the current upper limit of 30 minutes at an emergency heat stress index above 38 °C. Heat stress is a significant health and safety hazard for all those working underground, with risks heightened during emergency rescue or maintenance work. Personal protective clothing that keeps rescue teams cooler – and therefore safer – for longer periods could make an important contribution to the zero-harm aim. In the first trials, jackets fitted with pouches containing eight lightweight, frozen gel packs were tested during physical exercise. Heart rate, body and skin temperature and sweat rates were measured.

Our capabilities

Geotechnical sciences
Geotechnical sciences

Geotechnical sciences – or rock engineering – focuses on how modern mining practices impact mine operations, as well as the skills that will be required in the future. Typical projects cover areas such as geotechnical data acquisition, rock mass characterisation, numerical modelling and novel technology applications. We collaborate closely with scientific peers in geophysics on aspects such as reef topography, structural mapping, cavity detection and orebody delineation.

Mining engineering
Mining engineering

Our multidisciplinary team has extensive experience in developing practical, bespoke solutions to technical challenges facing the mining industry. We apply expertise in mine planning, technology adoption, skills development and operational health and safety interventions to optimise performance across areas such as ventilation and environmental engineering, socio-economic issues, ergonomics and fatigue management.

Occupational health and safety
Occupational health and safety

We support the mining industry in achieving its zero-harm objective by researching safer mining methods, assessing the health and safety of women in mining and developing innovative safety solutions. The work is underpinned by sophisticated, state-of-the-art facilities and infrastructure.
