Speaker
Mr ANJAN KUNDU
Senior Technical Director And Business Group Leader
GHD Pty Ltd
Risk could escalate during transition from ‘care and maintain’ to ‘active closure’ – Owners beware
10:30 AM - 10:40 AMBiography
Anjan has over 34 years of civil engineering experience in tailings dam design, operation, closure, tailings management and water engineering. He has worked for major Dams (Water and Tailings) projects in Australia, USA, Canada, Laos, Philippines, India, Malaysia, Kenya, Ethiopia, Papua New Guinea, Nigeria, and France. He has participated in the strategy development, planning, design and review, construction planning and quality assurance, project governance and compliance of multiple projects from concept to closure. Anjan has participated in the training workshop for operators and tailings engineers to share the knowledge in relation to operation and progressive closure (PRCP) of the facilities. Anjan is also involved in many Tailings projects undertaken by ICMM and non ICMM members. Anjan has participated in several bauxites, copper, manganese, coal, lead, zinc, gold, iron ore and silver tailings facility design, construction, operations, and governance. Some of this storage facilities are over 150m high. Anjan’s has strong skillset in advising mining organisations in stewardship, peer review, dam safety review (DSR) and risk assessment (including ALARP).
Currently, Anjan is also working on advising many organisations (mostly ICMM members) on their internal compliance process with GISTM (Global Industry Standard on Tailings Management).
Dr Chenming Zhang
Senior Reserach Fellow
School of Civil Engineering, University of Queensland
Two-year in-situ monitoring of water balance and vegetation growth on soil covers for slope tailings
10:40 AM - 10:50 AMBiography
Dr Chenming Zhang is a specialist in monitoring and modelling hydrological processes in groundwater systems and tailings storage facilities, in particular the evaporation induced mass and heat transport in soil and tailings, hydrogeochemical dynamics in aquifer systems and wast rock dumps. He has been developing IoT-based geotechnical and environmental instruments to monitor continuously and in real-time the weather, soil and water conditions.
Mr Andrew Friend
Project Manager
QLD Department of Natural Resources and Mines, Manufacturing, Regional and Rural Development
The remediation of an abandoned Tailings Storage Facility: Collingwood Tin Mine, Far North Queensland
10:50 AM - 11:00 AMBiography
I am a civil engineer with 17 years of experience in the mining industry, focussed on tailings dams, site drainage and water dams, roads and waste dumps. Through working several years within engineering offices followed by 8 years accumulated operational roles based on mine sites, I gained experience across each of the stages of the mine life cycle—including direct involvement with design, construction, operation, and remediation.
In my current role, I manage the care and maintenance of numerous abandoned mine sites within Queensland, progressing remediation projects where feasible. My expertise lies in delivering practical solutions for mine infrastructure and environmental management, to ensure risks are managed effectively.
