Considering that the underground mining of coal is used mining systems that have a high degree of complexity, and can reach cumulative lengths of tens of kilometers, associated with them we have the ventilation networks with the role of transporting important air flows with the help of special ventilation systems. The aeration networks are made up of all the mining works on which air flows are carried. Structurally, they comprise nodes and branches. The nodes of an aeration network are generated by the intersectio...
