Mr John Lowry
Landform Modeller
Department of Climate Change, Energy, the Environment and Water - Supervising Scientist Branch

Assessing the effectiveness of erosion predictions from a landform evolution model with field observations from a rehabilitated landform

1:05 PM - 1:20 PM

Biography

John Lowry has over 20 years experience as a spatial scientist and geomorphologist, focussing on rivers, wetlands, and uranium mining activities in Australia and south east Asia. His current research focus is on the application of data from drones for monitoring erosion on disturbed landscapes; and the application of landscape evolution models to model the impact of extreme climatic events on mine-impacted environments over extended periods of time.

Dr Pascal Bolz
Research Fellow
Sustainable Minerals Insitute

High-resolution erosion modelling using the RUSLE: An application to open cut coal mine operations

1:20 PM - 1:35 PM

Biography

Integrating and analysing spatial data across all components of the Earth system, including its anthropogenic modifications, allows to combine and analyse complex data and make it accessible to anyone. Spatial Science is capabale to perform in-depth scientific analysis and is directly connected to easily understandable mapping outputs. Pascal's work at the Sustainable Minerals Institute is focussing on regional perspectives on our transitioning mining regions across Australia and highlights vulnerabilties, challenges and opportunities for the transitioning industry. This work is already informing decision makers today about the opportunities and risks that lie ahead. On the other hand, Pascal works on improving environmental management practices is making an impact on the technical skillset of environmental staff in mine sites across Australia, improving their understanding of environmental modelling to address environmental challenges in mining using Spatial Science.

Mr Harley Thomas
CTO
Trust Provenance Pty Ltd

Traceability of native seed for mine rehabilitation

1:35 PM - 1:50 PM

Biography

In November 2018 Harley had the pleasure to begin employment at Boeing Defence Australia within their Data Analytics capability. Here he conducted a significant refactoring of Boeing Maintenance Workflow Analytics (BMWA), to improve maintainability and enable future growth of the product. This body of work resulted in more customer engagements within the business, and he was awarded a Boeing Wirraway Award along with his teammates as a result. Lately, he is working on a deep-learning model for network optimization and developing a solution where customers can realise this benefit in a production environment. This has been an excellent opportunity, as he has been able to merge his theoretical interests of Machine Learning he curated at University, along with solid Software Engineering and design principles learnt at Boeing. He prides myself on the ability to learn new concepts and applying them to provide business value to stakeholders.

Mr Roneel Narayan
PhD Candidate
The University of Queensland

Alternative mineral processing strategies for copper- gold tailings management

2:20 PM - 2:35 PM

Biography

Roneel Narayan is a PhD candidate at The University of Queensland. The title of Roneel's thesis is Alternative Mineral Processing Strategies for Cu- Au Tailings Management. The objective of Roneel's research is to identify operational changes that provide benefits for tailings management. The aim of the research is to enhance the overall value chain in mine and plant operations, as well as to determine the possible impacts and prospects of Coarse Particle Flotation (CPF) and High Voltage Pulse (HVP) technologies for tailings management. Roneel has over ten years of experience in heavy industry, plant maintenance, and process engineering across many sectors. A substantial portion of this experience focused on process improvement, optimisation, value chain analysis, and the implementation of Lean production techniques across a variety of industries. Roneel holds a Bachelor of Engineering Technology (Mechanical Engineering) from the University of the South Pacific (USP) and a Master of Business Administration and Master of Project Management from The University of Southern Queensland (USQ).
