| Abstract | The design of auxiliary ventilation system(AVS) and optimal equipment selection can be a problem, especially in case of very long drivages and high rock temperature. Algorithms for calculation of AVS parameters are basically developed by use of essential relationships from fluid mechanics. In a leaky duct, in addition to the variation of pressure, the flow rate varies along the duct and calculations are not straightforward. In the paper some of most successful models have been generalized and algorithms for calculations presented. Two basic models of leaking ducts are discussed: $1^{st}$ model for a duct with leakage through the flange joints; $2^{nd}$ model for a duct with an equivalent longitudinal aperture. The presented analytical system has been successfully applied to developing a computer program, named DAVentS. A sample problems are used to illustrate the efficiency and accuracy of DAVentS software in solving most common problems in the process of designing AVS and especially in the process of equipment selection. The design of auxiliary ventilation system (AVS) and optimal equipment selection can be a problem, especially in case of very long drivages and high rock temperature. Depending on shape and distribution of the leakage paths along the duct there can be two basic models: model for a duct with leakage through the flange joints and model for a duct with an equivalent longitudinal aperture. The AVS with a leaky ventilation duct is treated as ventilation network composed of simple parallel contours or meshes. For performance evaluation of an existing AVS it's necessary to obtain some data by measuring. Algorithms for calculation of AVS parameters are basically developed by use of essential relationships from fluid mechanics. By applying this algorithms computer software package named DAVentS is developed. It is possible to optimize design of AVS, by the combination of presented aerodynamicall calculation and appropriate economic analyses for ventilation costs. |
