RESEARCH OF THE ELECTRICAL EFFICIENCY OF DEAD-END VENTILATION WITH A LOCAL VENTILATION SYSTEM

ABSTRACT. The absence of rational management of local ventilation systems leads to an increase in electricity consumption for ventilating dead-end workings at an increasing cost of electricity. The aim is to achieve ventilation and economic efficiency with increased safety by controlling the ventilation technology. This paper presents results obtained from a laboratory test of a centrifugal fan which simulated the ventilation of a dead-end workings.
