Laboratory for Ventilation, Air Quality and Safety

Lab activity

The laboratory is equipped to handle the following scientific operations: measuring of ventilation and climatic magnitudes in mines, tunnels and underground openings during excavation and exploitation; measuring of concentration of harmful and dangerous gases and dust in mines, tunnels, underground openings and communal waste dumps; calculation of ventilation network; design of ventilation for mines, tunnels and underground openings.
