The Required Amount of Mine Air Passing through the Emergency Passage into the Mine
Original language description
In mines, providing proper ventilation during emergencies is a key aspect of ensuring safety and protecting human lives. In the case of indirect intervention by taking extreme measures (the closure of the entire mine using fire covers), it is necessary to ensure an emergency passage of miners to the surface providing a sufficient amount of mine air for them. The speed of the air must not exceed the limit for the safe passage of people, and must not cause unstable fan operation. The modelling of this problem in this case is carried out on a simplified ventilation network, in which two interconnected pits at a depth of 1000 m are displayed. The input data and limit values correspond to the valid legislation of the Czech Republic, but the resulting proposed methodology is universal and applicable to any mine or underground space that is artificially ventilated, and the parameters of the ventilation network are known. The issue of safety is always the main and key element of underground mining or underground work, and this article provides a model example of how to approach it even in the most difficult situations.
