The project planned to extract more than six million tonnes run-of-mine per year for the thermal coal export market. The mine included open-cut and underground areas. Coal was to be transported via rail to the export terminal facility. The project life was more than 20 years.
Recognising The Advitech Group’s Simulation Modelling Services (SMS) as a leader in modelling and analytics technologies, the SMS team was engaged to review supply chain logistics to ensure target throughput levels could be achieved and proposed infrastructure was appropriately sized.
Simulation modelling provides a means of understanding the likely performance of supply chains with complex interacting subsystems. Having developed numerous models of mining supply chains, SMS knew that the Arena simulation software was eminently suited to simulate and evaluate the supply chain operations.
SMS worked with project stakeholders to review the proposed supply chain design and establish a “base case” scenario representing the most likely value of parameters and assumptions to be provided as input in the modelling system.
Broadly, the Arena model simulated:
- production from both underground and open-cut sources
- stockpiling of coal, as necessary, in ROM and product stockpile
- coal preparation plant (CPP) operations
- train load out (TLO) operations
- arrival of third-party trains into the proposed balloon loop
- transit of trains to the export terminal
- arrival and loading of export vessels for delivery to the customer.
Importantly, the Arena model incorporated the variability inherent in the proposed supply chain. Variability was applied to:
- mine production rates
- arrival of trains into the balloon loop
- arrival of export vessels to the port
- frequency and duration of unplanned delay events
- frequency and duration of weather delays.
By creating an Arena model driven by externally defined data, The Advitech Group’s SMS was able to simulate a large range of scenarios to provide an understanding of the impact that changes in parameters and assumptions had on overall supply chain throughput.
