Researcher biography
Dr Micah Nehrings' research interests are in: Mine Planning, Production Scheduling Optimisation, Optimal Ultimate Pit Limit (UPL) determination, planning for In-Pit-Crusher-Conveyor (IPCC) systems.
Micah is a Lecturer within the Division of Mining Engineering of the School of Mechanical and Mining Engineering. He leads the High Performance Surface Mining Research Group which is heavily focused on delivering high quality research outcomes in the planning and installation of In-Pit-Crusher-Conveyor (IPCC) systems.
Micah joined the School in 2011, after completing his PhD at The University of Queensland. Micah has since undertaken an early career academic program which has resulted in collaborations with European universities in Sweden, Germany and Kazakhstan. Micah has also developed an industry network that works with him in the implementation of some of his groups research outcomes.
Micah research outputs have been published in numerous high ranking journals including Minerals Engineering, Journal of the South African Institute of Mining and Metallurgy, Mining Technology and the International Journal of Mining, Reclamation and Environment.
