EPA-approved blast dispersion modelling

Delivering site-specific, intuitively designed environmental monitoring to plan intelligently

Do you need a fully integrated service that gives you a concise picture pre and post blast?

DTN APAC’s Blast Dispersion Modelling is a comprehensive weather, environmental and alerting system, enabling you to run simulations days in advance.

Entirely customised to your mining site, our dispersion services take precise weather forecasts, topography, pollutants and legislative requirements into account, leaving no stone unturned.

As simulations are run, you can visualise the trajectory and intensity of pollutants in relation to the local forecast and pre-set thresholds. Dust monitors and Tapered Element Oscillating Microbalance (TEOM) heighten forecast accuracy. With a clear, projected outcome you can pin-point the best day to blast.

Our cloud-based, fully auditable report trails assist you in fulfilling your license and legislative requirements. As blasts are executed supervisors and managers can add their pre and post blast observations to ensure requirements are met.

Let us help you make your critical decisions on when to blast, simple.

Get the complete environmental picture

When in-depth consideration of the surrounding towns and environment is required, you need to be precise in your projections. Powered by Opticast, DTN APAC’s advanced nowcasting and forecasting system, you can rest assured that reliability and accuracy are the bedrock for our dispersion modelling. Results are globally proven to give you peace of mind.

Precision Forecasting

Environmental and weather monitoring are brought to you by the experts in meteorology, with a globally proven track record.

Easy to Visualise

All data for your environmental observations and blast simulations are intelligently presented to keep full comprehension simple.

Auditable Reports

Clean and informative reports on both blast simulations and executed blasts give you an auditable trail, keeping you compliant.

Mitigate Risk and Visualise Outcomes

An integrated Fume Management Zone (FMZ) tool adds to the depth of your blast planning. A logical traffic light system indicates whether your simulated blast creates pollutants that are above or below pre-set thresholds at any ‘virtual’ or existing monitors. You can create FMZs within the system, making it simple to plan and mitigate against risk. All these details are easily visualised in clean and informative reports, allowing you to justify your decision making on when to blast.

Your needs are as individual as your business, and we collaborate with you to bring ease to your every day. Our teams of meteorologists and data scientists are there, every step of the way, to help you navigate your challenges.

We don’t do status quo, choosing instead to lead with next-generation science and a service tailored to you.

Make well informed critical decisions, with the most accurate and site-specific data at your fingertips.
