Provided the simulation is performing without errors or warnings, it is almost certainly simply returning the results of the input data placed within the model. Some parts of the mine may require a physical inspection — is the fan running? One of the most critical requirements of a Ventsim model is that it accurately represents the ventilation conditions in your mine.
Without an accurate representation of current conditions, future design using the model will not be accurate and could provide misleading or incorrect results. Custom Icons are a great way to more clearly show ventilation infrastructure icons or equipment within your ventilation model.
Unfortunately the airway sizes, friction factors, shock losses and fan performances are often not exactly known and can be difficult or time consuming to measure in some areas. Chasm Consulting introduces a new software package to help manage recording underground measure ventilation information.
These can be used to derive friction factors which can then be applied to other similar airways, and are probably better than using standard default friction factors. Accuracy represents the difference between modelled airflows and pressures, and the actual measured airflows and pressures. Work backwards from the main airflows to the surface and try to discover the discrepancy between the data put into the model such vetnsim airway sizes, frictions factors, regulators or doors, fans etcand the actual data of the mine.
If the mine is known to have a strong natural manuwl pressure presence, then this will need to be included in the model. This step requires a systematic audit or all information used and will be covered in more detail in a future article. There is no correct answer, but every engineer and consultant should have a target to aim for based on what the model is required for.

Dynamic Contaminants offer a way to simulate the second-by-second spread of a contaminant through a mine. The tedious job of accurately entering fan curve data has been solved.
Tutorial: Validating Your Ventsim™ Model – Ventsim
For this reason, validating your model with current actual ventilation data and conditions is very important. This will show discrepancies in design sizes and airway locations that may warrant further investigation. Funnily enough, engineers who do not consider over-break vejtsim design sizes, also forget to consider shock losses, and the effect somewhat cancel each other out across the model — but not always in manua, correct places.
Ensure all simulation parameters and settings are accurate.

Each major ventilation assumption resistance, friction factor, airway size, fan curve, shock losses, simulation settings such as compressible flows and surface temperatures and barometric pressures needs to be reviewed for accuracy. The notes can then be compared side-by-side with the simulated results, showing any discrepancies. Recirculation can be defined as any portion of mine airflow that travels through the same area more than once. More often than not, a major factor or item has been missed in the model simulation, and once resolved the simulation will perform as expected.
Has the drive or airway been filled with backfill or other fspaol For that reason, engineers will often use standard design sizes and default friction factors and shock losses to design a model.
Without an accurate representation of current conditions, future design using the model will not be accurate and could provide misleading or incorrect results. A model that is to be used to predict future expensive infrastructure and fans should target evntsim higher accuracy than perhaps a long term life of mine draft. Recirculated air has a number of undesirable and possibly dangerous consequences.
Some tips on creating accurate models: At other times, equipment moving about, doors opening or shutting, and other temporary mine disturbances can effect airflow measurements.
