The notes can then be compared side-by-side with the simulated results, showing any discrepancies. Your browser does not support the video tag.
Has the drive or airway been filled with backfill or other blockages? Is the door or regulator open or close? For that reason, engineers will often use standard design sizes and default friction factors and shock losses to design a model.
A model that is to be used to predict future expensive dn and fans should target a higher accuracy than perhaps a long term life of mine draft. Recirculation can be defined as manuap portion of mine airflow that travels through the same area more than once.
Funnily enough, engineers who do not consider over-break from 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.
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. 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.
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. Some parts of the mine may require a physical inspection — is the fan running? ventskm

Chasm Consulting introduces a new software package to help manage recording underground measure ventilation information. Custom Icons are a great way to more clearly show ventilation infrastructure icons or equipment within your ventilation model.
Dynamic Contaminants offer a way espail simulate the second-by-second spread of a contaminant through a mine. Some tips on creating accurate models: Without an accurate representation of current conditions, future design using the model will not be accurate and could provide misleading or incorrect results. Without an accurate representation of current conditions, future design using the model will not be accurate and could provide misleading or incorrect results.
Accuracy represents the difference between modelled airflows and pressures, and the actual measured airflows and pressures. The tedious job of accurately entering fan curve data has been solved.
Ensure all simulation parameters and settings are accurate. One of the most critical requirements of a Ventsim model is that it accurately represents the ventilation conditions espaaol your mine.
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 mahual on what the model is required for. Recirculated air has a number of undesirable and possibly dangerous consequences. This will show discrepancies in design sizes and airway locations that may warrant further investigation.
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. This simulation differs from the normal ‘steady state’ contaminant and gas simulations in that ventilation models can show em progress and concentration at any time. Majual this reason, validating your model with current actual espakl data and conditions is very important.
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.
