Abstract

Purpose. Ground of complex approach to the decision of question of increase of energy-effectiveness of main fans during work on a mine ventilation network. Methods. Analysis of the existent state of ventilation of mine ventilation networks (MVN) offered for the ground of complex approach chosen to creation of energy-effectiveness technology of object – Donetsk Fuel and Energy Company (DFEC) and existent methods of organization of energy-effectiveness work of main fans (VF). Results. Three ways of decision problem of increase of energy-effectiveness of the MF application for the MVN ventilation are described: joint planning of the MF and MVN subsystems with the maximal account of factors influencing on rejection of descriptions of the designed and real systems «MF - MVN»; adaptation of the MF and MVN subsystems to the terms of complexing in the real terms; the MF replacement at impossibility implementation of terms of safety and technological factors of existent MF in the areas of their industrial use; use of additional measures (increase k.u.m. of managed electricity drive on condition of possibility adjusting of the aerodynamic parameters of MF, pressurization of over-mine buildings); analysis and optimization areas of MF interinfluence with the purpose of diminishment of non-productive losses of depression on overcoming resistance of jointly working MF in the area of their interinfluence. A conclusion about possibility decision of task with the receipt of eventual result without violation requirements of safety by only successive implementation of the transferred measures is done. Scientific novelty. It is offered complex approach to the decision task of increase of MF energy-effectiveness during work on MVN taking into account technological factors and facilities and analytical method of analysis of degree of the mutual influencing of MF and decline of its harmful consequences first. Practical meaningfulness. The got results will allow to promote MF energy-effectiveness, adequacy of mathematical model of the system «MF - MVN» to its real analogue, that will allow to use the topology and parametrical features of the real system «MF - MVN» for the decline of MF mutual influencing, and use the economic feasibilities of MF for perfection of the MVN ventilation.
