AFRIROCK CONFERENCE 2025
AMC Consultants is excited to present at the AfriRock 2025 International Rock Mechanics Conference, taking place at Sun City, Rustenburg, in South Africa from Monday 21 July to Wednesday, 23 July 2025.
Jeanne Walls, AMC's Principal Geotechnical Engineer, will be presenting on Geotechnical and Operational Risk Review for an Ultra-Long Ore Pass in a Caving Operation, and will also be chairing the Caving session on Day 1 of the conference.
The AfriRock 2025 conference spotlights cutting-edge technologies such as modern geotechnical data collection techniques, 3D visualization software for geotechnical analysis, computer modelling, mechanization, and more which all play a crucial role in advancing mining operations across the African continent
This international forum brings together engineers, academics, suppliers and manufacturers to present and discuss the latest advancements in rock mechanics and geotechnical engineering.
AMC at the Conference
Conference - Day 1
Session: Caving
Session Topic: Assessing the role of stress distribution on mine layout design in Block Caving Mine
Date: Monday, 21 July 2025
Time:
14:40 PM - 15:00 PM
Chair: Jeanne Walls, Principal Geotechnical Engineer
Conference - Day 2
Topic: Geotechnical and Operational Risk Review for an Ultra-Long Ore Pass in a Caving Operation
Author and Presenter: Jeanne Walls, Principal Geotechnical Engineer
Date: Tuesday, 22 July 2025
Time: 9:35 AM - 9.40 AM
The presentation will illustrate conditions in which an ultra-long ore pass arrangement within a caving operation must be developed to ensure that the ore handling system is effective for the required mine life. Geotechnical stability together with operational management requirements are included, as are challenges of benchmarking against limited industry examples to determine the feasibility of commissioning such a system.
