April Tech Talk - How engineers and geos are using digital twin technology for mine-to-mill and pit-to-port.

PD Hours
How engineers and geologists are using machine learning for digital mine-to-mill and pit-to-port value chain optimisation.

About this event

Through a series of international case studies, this presentation will demonstrate how digital twin machine learning software sustains the benefits of mine-to-mill and pit-to-port.

Specifically, these case studies will show how mines are using machine learning to implement digital twin models to;

a) add variables to the block model e.g. geometallurgy, product quality and materials handling rates

b) simulate drill and blast designs using historical performance and;

c) dynamically optimise plant set points in near real-time using best operator performance and dynamically responding to changes in ore characteristics.

Raw mining data is by integrated, automatically corrected and calibrated using purpose-built data valorisation algorithms.

Whilst ore tracking, machine learning and mathematical optimisation are the technologies enabling digital twin value chain optimisation, this presentation will also discuss success factors for long-term implementation of digital mine-to-mill and pit-to-port software.


Dr. Penny Stewart

Mining Engineer and Founder and CEO of PETRA
Dr Penny Stewart is a mining engineer and the founder and CEO of PETRA. Penny worked on mine sites for five years before obtaining her Queensland 1st Class Mine Managers’ Certificate of Competency. It was during her time working in the underground and open pit mines of WA that she learnt how geological uncertainty affects our ability to mine to plan. This experience led her to undertake PhD studies at University of Queensland’s JKMRC, where she developed statistical models to predict the mechanical behaviour of rock and was awarded the Ian Morley Prize for this work. In 2015, Penny founded PETRA with the hypothesis that the engineering behaviour of rock throughout a mine is best estimated by feeding back 100s of millions of tonnes of actual mine performance data into engineering models and optimisations. Five years later Petra’s flagship product, MAXTA software suite does exactly that.
