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

  • Alternative explosive formulations
    Since 2014 I have been involved in the development of novel explosive formulations to eliminate nitrogen oxide emissions (fumes) after rock blasting. The Australian Coal Association Research Program (ACARP) has contributed significantly to this as it is an issue affecting Coal operations. The idea to solve this problem came from one of my PhD students and involves replacing ammonium nitrate with hydrogen peroxide as the main oxidizer in explosives. We are currently at the testing stages and are facing many challenges, one of which is making sure that the product is stable in blastholes over long periods. To that end we have looked at different alternatives such as manufacturing higher density prills using different types of cross-linkers (gums) and sustainable fuels. We are also looking at surfactants and other type of stabilizers to make peroxide more stable.
  • Blast fragmentation and damage modelling
  • Fragment conditioning
  • Blast performance monitoring
  • Open pit and underground drilling and blasting
  • Explosive rock breakage

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.
