World-class ventilation-optimized systems drive energy savings to contribute to net-zero commitments

Ventsim originated as mining management software in 1993. Today it ensures operations within mines and tunnels are safe and efficient. Our core team of developers are specialists in underground and open cut environments and possess unique programming skills to make sure that our software is designed to suit the demanding requirements of underground ventilation design and operation.

Ventsim DESIGN

  • Compressible Flows – compressible airflows effects at depth are modelled
  • Thermodynamic environmental simulation
  • Heating and Cooling – includes heat or refrigeration options in network analysis
  • Rock Thermal Input – predicts heat and moisture emanating from rock strata
  • Diesel Equipment – predicts heat and humidity generated by diesel equipment
  • Natural ventilation – uses thermodynamics to simulate natural ventilation effects
  • Dynamic blasting – Blasting fume animated dynamic spread time and clearance time dispersion
  • Diesel Particulate Simulation – utilises diesel engine sources to estimate DPM levels throughout the mine
  • Dynamic Heat and Gas Distribution – Individual heat and gas time based simulation and spread through model with graphing

Ventsim CONTROL

  • Achieve energy savings on your ventilation system of between 10 to 70% by increasing system efficiency and reducing power use
  • Maximise health and safety by automating ventilation equipment and increasing airflow to active levels
  • Increase production by clearing blast gases faster, decreasing downtime up to 3 hours per production blast
  • Reduce carbon footprint by optimising the system and monitoring the reduction of tonnes of CO2 emissions
  • Maintain safe and compliant working conditions by reducing and monitor contaminant gases

Airflow Regulators & Dampers:

  • Precise, verifiable ventilation control with automatic or manual options
  • Automatic air flow regulator with actuator and the optional grille
  • Automatic air flow regulator frame

Ventsim™ DESIGN

Ventsim DESIGN is a complete integrated mine and tunnel ventilation software package for the design and testing of ventilation circuits including airflow, pressure, heat, gases, power, radon, fire and many other types of ventilation information.

The software enables engineers to accurately model, design, evaluate, and optimize underground mine and tunnel ventilation systems by creating an accurate simulation of the ventilation environment. Real-time animated 3D graphics represent actual airway dimensions and shapes with animated airflows.

Ventsim DESIGN is an expert tool that’s useful in all stages of ventilation design, from assessing needs and selecting hardware in the early planning stages to ongoing optimization of everyday operations in a working mine or tunnel.

Ventsim™ CONTROL

Ventsim CONTROL utilizes intelligent software connected to hardware devices to remotely monitor, control and automate airflow, heating and cooling to deliver safer, more productive and lower cost ventilation for your mine.

Ventsim CONTROL provides complete management of the ventilation system and includes an in-built energy reporting tool tracking ongoing underground ventilation energy consumption. The solution is scalable from manual remote control right up to a full Ventilation on demand (VOD) system, where the system adjusts mine airflow in real time based on vehicle and personnel position. This can be extended to include Cooling on Demand (CoD) functionality allowing users to monitor temperatures at deeper levels and push back cooled air more efficiently.
