ABSTRACT
The design of auxiliary ventilation systems for long drivages and tunnels requires the installation of multiple fans and it has vital importance. If the fans are installed next to each other air leakage in duct is high. Therefore, the fans are installed in series and separated from each other by rigid ducts of fixed or variable length. For a constant length duct design problem may be approached in two ways.
by deciding that the fans are installed at equal intervals and selecting the appropriate fans.
by selecting the optimum locations for fans of given characteristics.
In this study, the design procedures of each approach are presented as solution algorithms. Each algorithm comprises complex, time consuming and boring iterative calculation procedures. Thus, a computer package program based on the algorithms has been developed. The algorithms and the computer program have been applied on a selected long drivages.
