The Advanced Orebody Knowledge (AOK) programme is aimed at providing operational and technical personnel with information and knowledge that will contribute to optimal extraction and zero harm objectives. This knowledge is required ahead of mining to adequately inform day-to-day tactical as well as long term strategic decision-making.
The Advanced Orebody Knowledge (AOK) programme is designed to improve the safety, efficiency, and effectiveness of mining by enhancing geological understanding ahead of the mining face. Its goal is to create a “Glass Rock” environment, enabling better planning and risk management. By using advanced technologies, the programme identifies geological hazards early—such as faults, dykes, and gas intersections—helping to prevent disruptions, improve safety, and support optimal extraction. As mining operations extend deeper and further, the AOK programme becomes increasingly vital as it provides the necessary geological knowledge to navigate the complexities.

On 25 August 2023, Michelle Pienaar, Programme Manager of the Advanced Orebody Knowledge (AOK) Programme at the Mandela Mining Precinct, led a webinar highlighting innovative efforts to promote sustainable mining. The session focused on the development of cost-effective, non-invasive technologies aimed at improving orebody transparency in deep and complex underground environments. These tools enhance rock mass characterisation, detect geological hazards, and support safer, more efficient mine planning.
At the heart of the Advanced Orebody Knowledge programme lies AOK CORE—a concept that captures both the literal and symbolic meaning of “core.” In geology, a core is a cylindrical section of rock that reveals the structure and story beneath the surface. In this programme, it represents the fundamental drive to understand, connect, and innovate around South Africa’s diverse orebodies. AOK CORE reflects the essence of our work: deep insight, shared knowledge, and the pursuit of smarter, safer, and more sustainable mining.
The key challenge is gaining real-time insight into conditions at the mining front, particularly geological and ground stability factors, to enhance operational efficiency and safety. A primary concern is preventing falls of ground (FoG), a persistent and critical risk in underground mining. Several factors hinder these objectives, including:
Future efforts focus on AI integration, cost reduction, improved durability, and real-time processing to enhance safety and efficiency.
Ongoing research under the Advanced Orebody Knowledge (AOK) Programme focuses on refining and integrating technologies to improve geological understanding and safety at the mining face, such as:
With the optimal extraction and ‘’zero harm’’ objectives, technologies are being investigated, such as the Ground Penetrating Radar, to assist with identifying potential hazards on the mining face. There will also be a focus on positioning systems to enable scanning/assessment of the hanging wall integrity. GPR 3D modelling trial surveys will be conducted and, with Infrared (IR)/Thermography, one would be able to enrich GPR information. Attention will also be given to positioning systems so as to enable scanning/assessment of the hanging wall integrity. The deployment platforms with associated positioning systems will enable fast acquisition of georeferenced 3D data sets.
Future efforts focus on AI integration, cost reduction, improved durability, and real-time processing to enhance safety and efficiency.

There is a need for Real-Time, On-Site Ore Analysis
Future efforts focus on AI integration, cost reduction, improved durability, and real-time processing to enhance safety and efficiency.
Global Positioning System (GPS) technology is widely used for navigation and location tracking. However, GPS signals cannot penetrate solid materials such as rock and soil, making it ineffective for underground mining and tunneling operations. To address this limitation, Reutech Mining has developed an Ultra-Wideband (UWB) location tracking system, which provides accurate real-time tracking in GPS-deprived environments.
This project aims to enhance the existing Reutech Mining Real-Time Location System (RTLS) to improve efficiency, user-friendliness, and industry-wide applicability. The enhancements will focus on three key objectives: auto-locating anchors, universal data export formats, and integrating server functionalities into tablet computers.
