Overview

Dr Onederra is a senior lecturer at The School of Mechanical and Mining Engineering of the University of Queensland and is the Technology Leader of Explosives and Blasting Engineering at Mining3, an internationally recognised research centre in Mining innovation.

Dr Onederra holds a Bachelor of Engineering (Civil) with Honours from the University of Melbourne, Masters of Engineering Science and PhD from the University of Queensland. Has over 20 years of experience in the field of explosives engineering, blast design & analysis, performance monitoring and process optimisation. He has been actively involved in applied R&D and expert consulting in several mining operations and associated clients in Australia, South America, Africa and Europe.

He is recognised for contributions in blast performance monitoring, applied modelling and process optimisation, with developments in predictive fragmentation modelling embedded in commercial software used by industry in over 60 countries. He has a strong record of publications in international conferences and top rated mining journals. In 2014 he was awarded the Douglas Hay Medal from the Institute of Materials Minerals and Mining (UK) for the best journal publication contributing to the further understanding of confined blasting techniques such as preconditioning and de-stressing.

His leadership in the field of explosives and blasting engineering technology provided the foundations for the recent establishment of one of the first independent research groups involved in the development and testing of novel explosive formulations. In the last 3 years he has attracted in excess of $2M of funding with significant growth projected over the next five years. Dr Onederra has always been actively engaged with industry through a wide network of contacts in Australia and Overseas, particularly Latin America given his background and ability to communicate in Spanish at the corporate, technical and operational levels

Research Interests

  • Open pit and underground drilling and blasting
  • Blast performance monitoring
  • Fragment conditioning
  • Explosive rock breakage
  • Blast fragmentation and damage modelling
  • Alternative explosive formulations

Research Impacts

My area of expertise is in the science of explosive rock breakage, together with the development and implementation of advanced blasting engineering technologies. My research currently focuses on novel explosive formulations to minimise environmental impacts, development of advanced sensors and blast performance monitoring techniques; engineering design and modelling tools to improve safety productivity and minimise the energy footprint of mining activities.
