AQ2 Pty Ltd
Jon is a hydrogeologist with over 30 years’ consulting experience in local and international mine water management. Much of this work has been associated with open pit and underground mine inflow control, and pit slope and underground pore pressure control. Over the last 15 years or so, he has been commissioned by many international mining companies to provide high level technical and due diligence reviews relating to mine dewatering and depressurisation.
Over his professional career he has been a mine geologist and a hydrogeologist with the Geological Survey of WA before starting his consulting career with Australian Groundwater Consultants in 1983. He was a founding director of Aquaterra in 1998 and continued with the group as a technical director, and then became part of the RPS Group in 2010. He recently left RPS to join a number of his old Aquaterra work colleagues at AQ2, a specialist mine water management group.
Principal Geotechnical Engineer
Christan has worked for organisations such as MMG, AngloGold Ashanti, BHP, Placer Dome, Harmony Gold and WMC at numerous underground and open pit operations across Australia and Africa. This has allowed Christian to experience and work on challenging ground conditions and backfill requirements across diverse commodities, mining methods and cultures.
Dr Sanjive Narendranathan
Technical Director – Mining Geotechnical Engineering
GHD Pty Ltd
Sanjive is a chartered mining professional and a fellow of the Institute of Engineers Australia. He has over 15 years’ experience in the field of Mining Geomechanics. His operational experience includes responsibility for ground control at KCGM’s Super Pit and Mt Charlotte (underground) operations, where he undertook a number of applied research projects on topics such as final wall blasting techniques for open pit batters underlain by historic underground workings and underground support design requirements in ‘high stress’ conditions. He spent 10 years as a consulting engineer with Coffey Mining (7 years) and the Infra Tech Group (3 years), where he undertook a number of geotechnical designs and feasibility studies for clients such as Rio Tinto, BHP, Barrick, Newmont, for projects across a number of commodities in Australia, Asia and Africa. He has also been called upon to provide expert technical and forensic advice on a number of sensitive cases involving geotechnical engineering issues and disputes for firms such as Clayton UTZ and MinterEllison.
He spent one year with the mining regulator in Victoria, as a geotechnical advisor, where he was responsible for providing advice to the office of State Resources Minister on Victorian mine and quarry stability requirements. In early 2018 he joined GHD as technical director (mining) geotechnical engineering, and is focussed on the closure related stability considerations for Brown Coal Mines in the Latrobe Valley Region of Victoria.
