ABSTRACT

Ventilation networks in underground mines may be affected by items such as: locating
of objects in air path or destruction of support systems which would result in pressure
loss and distortion of air flow. By considering the necessity of keeping the network
performances at appropriate level in such conditions, in this study, definition of
ventilation network evaluation has been proposed which indicates the network
reliability in an uncertain situation. Economic and safety concerns in mines involve this
fact that the ventilation network should provide the amount of air in an effective,
reliable and safe manner. For designing or evaluating a ventilation network to obtain the
devised purposes, designers need criterions and regulations which through them a
network with proper performance is achieved. So for, there is no determined approach
to analyze the efficiency of network. It seems that calculation of network components
reliability and then, at last, estimation of network reliability is the best measure in order
to achieve this aim. So, first, the reliability of each branch and network should be
defined. The described method in this paper is developed by considering conventional
methods to determine reliability in the transportation and electrical network.
