Research Topics at the Division
The Mine Ventilation Division conducts a broad range of scientific research and development activities in the field of mine ventilation. This includes the study of unsteady air and gas flow in complex networks of workings, ducts, pipelines, and other ventilation systems under flow disturbance conditions. The division also develops methods for measuring gas flow using thermoanemometry and anemometry, employing modern instruments for measuring flow velocity, temperature, and gas pressure, which are mainly designed and manufactured at the Institute. Additionally, advanced numerical studies are carried out to support the modeling of gas flows in the mining environment and complex ventilation systems.
