| Description | 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. The design of auxiliary ventilation systems for long drivages and tunnels requires the installation of multiple fans and it has vital importance. This chapter presents the design procedures of each approach 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. Auxiliary ventilation may be applied into three basis types, forcing, exhausting, and overlap systems. The choice between forcing and exhausting arrangements depends mainly upon the pollutants of greatest concern, dust, strata gas or heat. The best way to ventilate a dead-end working area is to use auxiliary fans and ducting. Because of the nature of the ducting and numerous joints, complete elimination of leakage from or into the duct line is impossible in practice. Book Name: Mine Planning and Equipment Selection 2000 |
