ABSTRACT
The ventilation process is considered to be the primary protection in underground
exploitation of minerals. Due to this fact, it has major importance in ensuring and
maintaining the health and safety conditions on the pathway of mine workings.
A fire resulting from the oxidation or from the burning of organic substances at low
velocities, besides the harmful effect of the exposure to burning gas, the thermal effect resulting from the excessive increase of burning gas and organic substances
temperatures, it also has an aero-motor effect upon the ventilation network, resulting in the forced intensification of the ventilation in the area of influence. The fire changes the airflow conditions because it has a higher viscosity, fact which leads to the local increase of apparent resistance of the mine working in which the phenomenon occurs. In certain conditions it may lead to the local reverse of airflow,
with harmful effects for the underground workers.
