Miguel Araos

Miguel Araos holds a BChem (honours) from University of Chile (Chile), MSc from the University of Sydney (Australia) and a PhD on detonation physics from the University of Queensland (Australia). He has over 25 years of experience in mining explosives research, development and application.

He started his career as development chemist at a detonator company (Tec Harseim, now Dyno Nobel). He then became a development chemist at Enaex (the largest explosives manufacturer in South America). There he was in charge of adapting sensitising (gassing) technology for mining bulk explosives to local conditions.

In 2000 he moved to Australia, where he joined Dyno Nobel Australia. He continued working with emulsion explosives’ technology. In 2003 he moved to Dyno Nobel USA in Salt Lake City, where he worked with emulsion rheology to determine emulsion crystallisation during pumping.

In 2004, he returned to Australia and joined Orica. He participated in the development of the UN tests series 8(d) MVPT and was also in charge of regulatory tests (UN test series 1, 2 and 8). He also developed UG products and provided advice to operations all over the world on the use of AN prill for emulsion manufacture or as use as prill.

In 2009 he joined the QLD Explosives Inspectorate. His main functions were to authorise new explosives, review risk assessments for new emulsion manufacturing plants, process safety auditing and incident investigation. He provided input on the SAFEX Code for Storage of AN.

In 2012 he took up a position in an oil and gas company to be in charge of explosives and radioactive material compliance. The following year, he enrolled into a PhD program to study a NOx -free explosive he invented (based on hydrogen peroxide). This research was sponsored by the Australian Coal Association Research Program (ACARP). One of the main outcomes of his PhD is a revised theory for the ignition of non-ideal explosives. In 2016 he joined CRCMining as a project leader in explosives technology to show the capabilities of the new HP based product and engage industry in the research. In 2019, he started STX technologies and support the technology of explosives manufacturer.

He continues to have an association with the University of Queensland to support the current and future R&D in the mining explosives area.
