ROM Bin Structural Health Monitoring
Hail Creek, QLD
The main objective of this project was to develop a technique for reliable, cost-effective, and objective assessments of the structural condition of the infrastructure used in coal mining; eliminate the subjective, conservative assessments, and enable data-driven decision-making to improve reliability. To accomplish these objectives, Mincka recommended the installation of a Structural Health Monitoring (SHM) system for the ROM Bin structure at the mine.
This project was challenging due to the high level of technical expertise required in the latest technologies and methodologies. In addition, complex mathematical model results had to be converted into useful data, to improve the structural integrity management process. There were also significant restrictions around the installation and commissioning of the system, due to the shut-down required to implement the processes.
In order to achieve the project objectives, Mincka developed a set of algorithms based on real-time measured data, using accelerometers and strain gauges to identify changes or damage in the structure’s condition. The algorithms are based on modal, structural and fatigue analysis. Mincka also designed the measurement system required for this.
We also developed an algorithm to conduct risk assessments and remaining life estimation, based on a stochastic modelling approach, which meets Australian standards. The results are also in accordance with the client’s governance documentation and enabled data-driven decision-making that is both accurate and efficient.
The balance of the project included the development of a user interface that integrates 3D visualization of the structure and shows the results of the implemented algorithms. The user interface for the functional layout was also provided to ensure full access and visibility into all key areas.
