If your goal is to improve an operating underground mine’s ventilation, my first choice would be Ventsim DESIGN + Ventsim CONTROL. It is one of the strongest end-to-end options because it combines detailed ventilation-network simulation with operational ventilation-on-demand (VOD) control.
| Software | Best for | Simulation | Real-time / VOD | My take |
|---|---|---|---|---|
| Ventsim DESIGN + CONTROL | Best overall / operating mines | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | My first choice |
| VUMA-network + VUMA-live | Deep/hot mines & environmental management | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | Excellent alternative |
| Ventsim DESIGN alone | Ventilation engineering/design | ⭐⭐⭐⭐⭐ | — | Best if you don't need automation |
| VUMA-network alone | Network modelling & thermal studies | ⭐⭐⭐⭐⭐ | — | Particularly strong for heat/cooling |
| Deswik ecosystem + ventilation tools | Integrating ventilation with mine planning | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | Best if mine-wide planning integration is paramount |
Ventsim DESIGN is a very mature 3D ventilation simulator. It handles airflow and pressure networks plus heat, humidity, gases, diesel particulate, radon, fire, blasting, refrigeration and dynamic time-based scenarios. It also supports importing mine geometry from CAD/mine-planning systems.
The particularly compelling part for an existing mine is Ventsim CONTROL. It connects the model/software environment to ventilation hardware and can remotely monitor and automate fans, airflow, heating and cooling. It supports VOD and integration with third-party hardware.
So you can move from:
survey data → calibrated model → "what-if" simulation → optimized ventilation design → sensors/SCADA → automated VOD
rather than having a simulation program that simply produces engineering reports.
Ventsim also has a dedicated VentLOG component for managing ventilation surveys, including airflow, gas, temperature and pressure measurements—useful for maintaining calibration of the model against the real mine.
VUMA deserves a very close look, particularly if yours is a deep, hot underground operation.
Its network solver simultaneously considers aerodynamic, thermodynamic and contaminant behaviour. VUMA specifically emphasizes modelling the heat loads encountered in deep mines, including auto-compression, rock heat, development faces and cooling systems.
Its suite is also unusually complete:
If you're dealing with high virgin rock temperatures, refrigeration, heat stress or very deep workings, I'd put VUMA essentially neck-and-neck with Ventsim.
Deswik is worth considering if your bigger problem is not just ventilation but coordinating ventilation with mine planning and scheduling.
Deswik's broader ecosystem integrates mine design, scheduling, operations and other technical disciplines. Its planning tools can incorporate ventilation restrictions as constraints—for example, a published underground case study describes optimization involving ventilation restrictions alongside production, equipment, fill and other constraints.
I'd therefore think of Deswik somewhat differently:
Ventsim/VUMA = ventilation engineering system of record
Deswik = mine planning/optimization ecosystem that needs to account for ventilation
For a ventilation department specifically, I wouldn't choose Deswik instead of Ventsim/VUMA without a very specific integration requirement.
If you have an existing underground mine and want to materially improve ventilation performance:
1. Ventsim DESIGN
Build/import the 3D mine network and calibrate it against actual ventilation surveys.
2. Ventsim CONTROL
If the business case supports automation, connect fans, regulators, sensors and other equipment for VOD.
3. Integrate with your mine-planning system
Use the ventilation model to test development, production and infrastructure changes before they're implemented.
4. Establish continuous model calibration
Don't treat the simulation as a one-off engineering study. Mine geometry, leakage, regulators, fans and production activity continually change.
Ventsim is currently particularly attractive because the vendor provides both the simulation and operational control layers, rather than requiring you to assemble completely separate systems.
The "best" software depends heavily on mine type and the problem you're trying to solve. For example, the optimal choice can change considerably between a 500-m-deep hard-rock mine trying to reduce fan power and a 2–4 km-deep mine where heat/refrigeration is the dominant constraint.
If you tell me (1) approximate depth, (2) commodity/mine type, (3) mine size/production, (4) whether you're trying to reduce energy, improve airflow/contaminant control, or automate VOD, and (5) what mine-planning/SCADA system you currently use, I can give you a much more specific Ventsim vs VUMA comparison and recommended architecture, including what I would actually implement first.

I need to model and control ventilation for an underground mine. Which software platforms are best suited for this?
To help narrow down which tool fits your specific operation, tell me:
I can provide more targeted guidance on implementation and feature sets.
| Ventilation-on-demand (VoD) |
| Real-time monitoring, remote control and automation of fans, airflow, heating/cooling; can interface with third-party hardware. |
| ABB Ability Ventilation Optimizer | Automated mine-wide ventilation | Sensor- and location-driven VoD, fan/regulator control, scheduling, feedback control and advanced multivariable optimization. Integrates with ABB Ability System 800xA. |
| ABB SmartVentilation | Integrated control/SCADA | Centralized monitoring/control, sensor control, calculated-demand flow control, scheduled/event-based control and online optimization. |
| Deswik | Mine planning integration | Strong underground design, scheduling and operations platform; useful for connecting ventilation requirements with mine development and production plans, although it isn't primarily a dedicated ventilation simulator. |
1. If your immediate problem is engineering the ventilation network:
Ventsim DESIGN is probably the first platform I'd evaluate. It is purpose-built for underground ventilation and supports both steady-state and dynamic analysis. Its current version includes modeling of airflow, heat, gases, DPM, radon and fire, among other functions.
2. If you already have instrumentation and want automatic ventilation:
Look closely at ABB Ability Ventilation Optimizer or Ventsim CONTROL. ABB's system can use personnel/vehicle location, air-quality sensors, flow sensors, equipment status and schedules to determine ventilation demand and automatically adjust equipment.
3. For a modern mine, I'd consider combining them rather than choosing only one. A sensible architecture is:
Mine design/schedule → ventilation simulation model → PLC/SCADA → sensors & tracking → VoD optimizer → fans/regulators → continuous feedback
That gives the ventilation engineers a calibrated digital model while the control system handles the real-time problem of delivering the required air where people and equipment actually are.
Don't evaluate these platforms solely on their simulation capabilities. For an operational mine, I'd specifically ask vendors about:
ABB, for example, describes a three-level progression from centralized supervision, through VoD, to real-time optimization using sensor feedback and advanced multivariable control.
My practical shortlist would therefore be Ventsim DESIGN + Ventsim CONTROL versus ABB Ability Ventilation Optimizer, with Deswik considered where tight integration with mine planning/scheduling is important.
If you tell me your mine type (hard-rock/coal), approximate depth, number of production areas, existing SCADA/PLC platform, and whether you already have VFD fans and tracking/sensors, I can narrow this to a recommended architecture and compare the platforms feature-by-feature.
Managing and simulating underground mine ventilation systems requires software that can model complex 3D networks, thermodynamic properties, airflow, and contaminant dispersion. Several major industry platforms handle both design/simulation and active control/Ventilation on Demand (VOD).[](https://ventsim.com/)[[2](https://www.chartindustries.com/Products/Ventsim)](https://www.chartindustries.com/Products/Ventsim)
