- Abstract
Explosion type phenomena which may occur at the level of a ventilation network generate changes of the network's structure determined mainly by the destruction of ventilation constructions. The flame front generates a high quantity of burning gases having an extremely high temperature, which leads to their rapid expansion. Over the entire length of the mine workings where the gas distensions occur, the workers subject to the event are exposed, beside the dynamic effect, to high temperatures and high concentrations of toxic and asphyxiating gases, respectively to the drastic decrease of oxygen concentrations, atmosphere which is incompatible with life. The phenomenon of the explosion causes serious disturbances in the ventilation system. May occur reversal of the direction of air flow, unventilated or poorly ventilated areas or destabilizing the functioning of active fan. These are a few reasons for that restore ventilation becomes priority. Within FFCS Coal RTD Programme was developed AVENTO project - Tools for Advanced Ventilation Methane Emissions and Control, which had one objective restore ventilation network, affected by explosion.
