VUMA-network is an interactive network simulation program that is used for the simulation of steady-state environmental conditions encountered in underground mines, and allows for the simultaneous simulation of:

  • Airflow
  • Air thermodynamic behaviour
  • Gases (including radon)
  • Dust emissions
  • Applications include:
    • Planning and design of ventilation systems
    • Verify environmental performance parameters
    • Running of what-if scenarios and trade-offs
    • Energy optimisation
    • Dust/gas tracing throughout an underground mine
    • Fault finding and trouble shooting
    • Tracking of contaminants resulting from a blast
    • Determine blast clearance time
    • Fire module
      • Considers combustion effect of fire on network, i.e. ventilation flow turnaround
      • Simulates the success of possible firefighting scenarios
      • Simulates existing fire control measures, e.g. doors installed to control a conveyor belt fire
  • Currently supported languages:
    • English
    • Spanish
    • Polish
  • Universities & mining schools
    • Please contact us directly to arrange for free, fully functional academic versions and relevant training material and support


Based on VUMA-network and interfaces with on-line monitoring of underground conditions. Employs several strategically selected inputs obtained from the mine’s instrumentations systems, to predict real-time environmental conditions throughout the mine.

  • Benefits include:
    • Real-time monitoring
    • Visualisation of underground ventilation conditions
    • Alarm when abnormal conditions are detected
    • Forward prediction of conditions
    • Daily reporting
    • Forward emergency planning and response
    • Planning energy conservation and changeover strategies
    • Risk analysis

Many industrial work processes create harmful airborne pollutants (ABP) that can cause occupational health related diseases. A local exhaust ventilation system is an engineering control system that captures dusts, vapours, and fumes at their source of generation and transports them away from the worker’s breathing zone. This prevents workers from inhaling these substances and reduces contamination of the general workplace air.

VUMA-lev is a evaluation and/or design tool for LEV systems ensuring correct volume flows, distribution, carry velocity etc. for LEV duct system network. The software is a valuable asset in determining the impact on the LEV system’s performance if geometry or elements are altered. VUMAlev is a LEV network simulator based on the flagship VUMAnetwork simulator used for mine ventilation, cooling, and environmental control which has been continuously developed over many years.


  • Evaluate existing LEV systems performance
  • Predict the impact on LEV system performance due to system alterations
  • Model/design new LEV designs


VUMA-lev can be coupled with a few strategic sensors and this results in a real-time monitoring of the LEV system to ensure that it is operating according to the design at any given moment. Alarms will be raised if the design criteria are not met.
