ABSTRACT
VENTMEX v0.1 is a computer application designed and developed by the National Institute for Research and Development in Mine Safety and Protection to Explosion, being the object of the Romanian Research Program “NUCLEU” PN 07-45-02-44. The software is portable on Windows operating systems and is a very useful tool for researchers and specialists from mining and industrial ventilation area, providing a simple and intuitive interface for inputs of “in situ” collected data. Based on these data – primary consisting by fan flow, Qv, fan pressure, Hv, mine flow, Qm, and mine pressure, Hm – and considering other operational specifications of the fan, the application calculates and prints in a tabular form the relevant parameters for characteristic curves design: pressure curve, power curve and efficiency curve. Graphic representations are displayed in separate windows, allowing a visual comparison of several data sets. Both inputs and results can be saved with .txt extension and graphics can be stored with .png or .svg extensions.
