This laboratory is related to the mine ventilation lesson. During the semester, the students are divided into 7-8 groups of 4 people, each of which performs the following tests:
Calculating and drawing the pressure and energy curves along the airway
Investigating the energy conversion along the airway
Testing the connection of fan in series and parallel systems and drawing their characteristic curves in each system
Testing the various ventilation models of road tunnels
Testing the sub-ventilation at dead ends using blowing and exhaust methods
Measuring the amount of air pollutants, velocity, and intensity of airflow
Laboratory-scale wind tunnel modeling
Laboratory Equipment
Underground Mines Ventilation System: Investigating all ventilation steps in mines and drawing curves of pressure and energy changes along the way
Laboratory Model of Road Tunnel Ventilation System: Investigating the road tunnel ventilation systems in transverse, semi-transverse and longitudinal methods
Laboratory Model of Subsidiary Ventilation in Underground Mines: Investigating the ventilation of dead ends in suction and ducting methods
Digital gas meter: Detecting CO-H2S-O2-CH gases in mines and public places
Speedometer, Thermometer and Unit Conversion: Determining air velocity per time unit, determining its temperature, and converting international units
Photometer: Determining the light in tunnels, mines, and other places.
