Abstract.
The expense of electric power on ventilation of mines depends on the amount of main fans (MF), their working regimes, MF interaction on an outgoing stream, qualities of vent network, coefficient of the useful use of the air and row of other factors given in a mine. These factors are very multidimensional, and for the removal of them different methods and facilities are needed: technical, organizational, multifactor design and others. The increase of power effectiveness of the MF work is the basic condition of perfection of mine ventilation. During realization of multifan ventilation there is the non-productive «overbalancing» of vent stream toward more powerful fanr and decline the same of efficiency of work both. The questions of decline of MF interaction on the outgoing stream of air and increase of aerodynamic quality of vent network are studied and is taken into account not enough. Varying within the limits of area of the industrial use by productivity and the MF pressure, it is possible, not violating the requirements of Rules of safety in coal mines to speed of air in objects-users, to attain optimum correlation of these parameters for examined MF. The method of calculation of the effective operating conditions of MF taking into account MF associate and areas-users of crisp air in MVN and on the basis of criterion of estimation of MF interaction degree is offered. It is shown that senescence of the mine workings, them encumber, bring in the wear of the MF elements certain error in vent calculations, and this factor must be taken into account. The method of calculation and determination of the rational operating MF modes was enhanced; the approach is different because it uses the coupled nonlinear dependences between pressure and the MF feed and air rates in the separate ventilation objects and because the mutual influence estimation criterion is applied. So the method cannot solve the task of substantial increase of ventilation energy efficiency. The problem is multydimensional and requires the complex use of technical, organizational and analytical calculation methods. However, modeling of the aerodynamic condition of the mine vent system using this method, combined with implementation of organizational and technical decisions, will allow receive positive high-quality changes of ventilation, and enable to increase the energy efficiency of the MF work.
Keywords: main fan, area of the industrial use, aerodynamic state of the vent system, power effectiveness.
