Abstract. The main fans, used on the mines of Donetsk fuel and energy company, and the reasons, influencing on effectiveness of their works, and its energy-effectiveness in particular, were described. It was marked, that the mode of working of main fans is largely determined by aerodynamic parameters of mine ventilation networks, which, in same queue, are determined by technological parameters and geomechanical factors of mine works conduction. So, the change of area of transversal section of the mine workings (subject to such changes in most degree are the unsupported ventilation workings) causes related to him decrease expense of air, in the turn influencing on the gas mode of working areas and possibility of origin on them emergency situations. Such interconnection causes the necessity changes of operations of main fans, for the area of its interaction area is included, and simultaneous solution the problem of saving level of energy-effectiveness ventilation of area taking into account influence of main fans, working for him (on condition work of each of them on description from the area of the industrial use). The method of decision of this task with the complex account of requirements of safety and energy-effectiveness of ventilation was offered.

Keywords: main fans, mine ventilation network, energy-effectiveness, safety, geo-mechanical factors.
