Ensure all simulation parameters and settings are accurate. At other espaool, equipment moving about, doors opening or shutting, and other temporary mine disturbances can effect airflow measurements.
Has the drive or airway been filled with backfill or other blockages? A model that is to be used to predict espoal expensive infrastructure and fans should target a higher accuracy than perhaps a long term life of mine draft. The tedious job of accurately entering fan curve data has been solved.
Tutorial: Validating Your Ventsim™ Model
Provided the simulation is performing d errors or warnings, it is almost certainly simply returning the results of the input data placed within the model. This will show discrepancies in design sizes and airway locations that may warrant further investigation.
For that reason, engineers will often use standard design sizes and default friction factors and shock losses to design a model. Accuracy represents the difference between modelled airflows and pressures, and the actual measured airflows and pressures.
Funnily enough, engineers who do not consider over-break esoaol design sizes, also forget to consider shock losses, and the effect somewhat cancel each other out across the model — but not always in the correct places.
Some tips on creating accurate models: 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. These can be used to derive friction factors which can then be applied to other similar airways, and msnual probably better than using standard default friction factors.
Some parts of the mine may require a physical inspection — is the fan running? Your browser does not support the video tag. Chasm Ventsjm introduces a new software package to help manage recording underground measure ventilation information. 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. Recirculated air has a number of undesirable and possibly dangerous consequences.
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. This step requires a systematic audit or all information used and will be covered in more detail in a future article. More often than not, a major factor or item has been espao, in mnaual model simulation, and once resolved the simulation will perform as expected. If the mine is known vengsim have a strong natural ventilation pressure presence, then this will need to be included in the model.

Ventsim™ 4 – Ventsim – 3D Mine Ventilation Simulation Software
This simulation differs from the normal ‘steady state’ contaminant and gas simulations in that ventilation models can show contamination progress and concentration at any time. One of the most critical requirements of a Ventsim model is that it accurately represents the ventilation conditions in your mine.
Dynamic Contaminants offer a way to simulate the second-by-second spread of a contaminant through a 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. For this reason, validating your model with current actual ventilation data and conditions is very important.
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.
