The mining and extraction sector in Australia is often impacted by severe weather events. Scientists predict an escalation in the severity of events and consequent risks due to climate change.
The impacts of weather events
- The health & safety of employees in the field is a primary consideration as the sector implements ‘zero harm’ policies and programmes
- Weather disrupts not only mining operations, but also transport links and supply chains
- Severe weather can damage infrastructure and assets, including communications networks
- Managing the environment and the airborne dispersal of contaminants, dust and fumes can be top-of-mind for mine operators
- The sector is also uniquely exposed to the risks of ignition from lightning strikes
Advanced weather guidance helps mitigate these risks.
MetraWeather’s mine dispersion modelling is based on the Weather Research and Forecasting (WRF) Model.
The development of WRF began in the latter part of the 1990s as a collaborative partnership principally among the National Center for Atmospheric Research (NCAR), the National Oceanic and Atmospheric Administration (represented by the National Centers for Environmental Prediction (NCEP) and the (then) Forecast Systems Laboratory (FSL)), the Air Force Weather Agency (AFWA), the Naval Research Laboratory, the University of Oklahoma, and the Federal Aviation Administration (FAA).
WRF is a numerical weather prediction (NWP) system designed to serve atmospheric research and operational forecasting needs. The model serves a wide range of meteorological applications across scales ranging from meters to thousands of kilometres.
For example, for a client’s NSW mining operations, two elements are modelled: coal dust particulates (PM10) and nitrous oxide fumes (NO2). The model is run twice a day and hourly images are generated for each element at two selected blast sites at the mine. Each image is a “worst-case scenario” snapshot of the surface accumulation over the next 6 hours if a blast were to occur at the time of the image.
We work closely with our customers to develop the optimal mix of forecast modules best suited to delivering value to your operations. Alignment with your HSE procedures, safety thresholds and communications channels is central to ensuring your operations derive the greatest security and value from our weather guidance.
