Keynote Speakers

Fifth International Conference on Block and Sublevel Caving

30 August – 1 September 2022 | Hilton Adelaide, South Australia

Keynote Speakers

Ryan Campbell
Chief Geomechanical Specialist
Freeport-McMoRan Inc., USA

Ryan has 20 years of geomechanics experience specialising in mass mining project development, strategic planning and operational support. After being stationed at the Grasberg operation, Ryan returned to work within PT Freeport Indonesia’s corporate geotechnical group. Prior to Freeport, he worked with SRK Consulting where experience was gained in open pit and underground mass mining operations in Canada and abroad. Recent areas of focus at Freeport include optimisation of cave and development sequencing, rock mass characterisation, excavation design, ground control, open pit/underground interaction, fragmentation forecasting and risk management. 

How companies operate caving mines can differ, often extensively, from what was originally envisioned during planning stages. Realities change as the project shifts from a paper design through construction, the first encounter with actual conditions, to cave establishment and steady state production. Much is learned along the way, including how an organisation functions (and responds to change), how the rock mass itself responds to caving, the robustness of the original plan to actual conditions and whether the cost and schedule estimates were reasonable or achievable. Once a mine is operational, strategy and tactics continue to evolve from initial plans as changes are made to deal with the realities of ground conditions, project logistics and market pressures. Invariably, such changes tend to result in schedule delays and cost increases. The intent of risk analysis is to capture the likelihood and consequence of such changes and to have mitigation processes in place to deal with the new conditions. As a planning and operational necessity, risk management at larger operations is typically established and maintained to at least a basic level. However, the systematic capture and application of lessons learned and opportunities (i.e. the feedback loop), tends to be less formally implemented. Critical institutional knowledge can be lost with staff departures or poor records capture. Case examples are provided to illustrate the benefits of risk, lessons learned and opportunity registries across multiple disciplines in large panel caves. Experience is shared on the linked utilisation of these tools, which has led to stronger organisational collaboration with more desirable safety and production outcomes. Differing vantage points from consulting, corporate and mine operations roles are explored based on personal experience.  

Simon Hanrahan
Corporate Consultant (Mining)
SRK Consulting

Simon has over 35 years’ international experience including the development and operation of block cave mines and operating open pit mines above caving zones. Simon has led projects across the whole resources value chain: all study phases, project implementation, construction and commissioning, and mine operations. Mine management and construction experience was gained in South Africa, Australia, and the USA in gold, coal, base metals, copper, platinum, industrial minerals, and diamonds. Since joining SRK in 2010, Simon has worked globally in project management, due diligence, and technical reviews for surface and underground mining projects, and lender construction oversight for development projects. His commodity experience also includes iron ore, lithium, graphite, nickel, bauxite, manganese, niobium, tungsten, potash brines, and mineral sands projects.

Katie Hulmes
General Manager, Transformation and Readiness
OZ Minerals

Katie proudly represents a more than 20-year engineering and mining career with diverse roles as a field engineer, environmental scientist, exploration hydrogeologist, approvals manager, scoping study manager, group environmental lead, project engineer, head of technical services and her current role as head of transformation and the Think & Act Differently incubator.

Katie’s technical skills were gained as a graduate of the University of Adelaide with a Bachelor of Science in Geology and Geophysics and a Bachelor of Engineering (Civil and Environmental) and her passion and drive stems from a curiosity and deep belief that the industry can create multi-generational change with a positive impact on regional communities and the environment.

She was awarded South Australia’s inaugural 40 Under 40 Young Entrepreneurs Award for her contribution to the minerals sector and continues to charter new paths for the industry and her peers. She has shown that through partnerships and transparency, you find opportunity. Katie can proudly point to initiatives that have emerged under her leadership with value created in community groups, with traditional owners, conservation organisations, research bodies, technology companies, and start-ups. Importantly, she takes time and commitment to continually develop both herself and her team, fostering a belonging culture where people are self-empowered to thrive and grow through their work.

Katie continues to advocate for shared value and for cross sector collaboration and is currently fulfilling voluntary positions at the South Australian Government Minerals and Energy Advisory Council, the Smart Satellite CRC Mining and Energy Advisory Board and, most recently, the South Australian Government Space Council and AROSE Advisor Board.

Pedro Landeros Córdova
Director of Geotechnical Engineering, El Teniente Portfolio of Projects

Pedro has over 15 years’ experience in underground geotechnical and geomechanical engineering. From 2008 to 2016, he worked as a geomechanical engineer at the El Teniente mine for the Esmeralda and Reservas Norte operating sectors and then for Dacita and Recursos Norte Projects.

Since 2016, Pedro has led teams of geologists and geomechanics for El Teniente future expansion projects. He is currently the director of geotechnical engineering of the El Teniente Portfolio of Projects, leading geotechnical ground control of Andes Norte, Andesita and Diamante projects.

His main experience and expertise relate to caving geomechanics and underground geomechanical risk management, mine-induced seismicity, rockbursts, hydraulic fracturing, and excavation design in high-stress environments with complex geomechanical conditions.
