The article describes the studies into the effect of the pulsating ventilation on the dust content, high moisture content and air temperature in underground excavations in terms of the mine safety improvement. Given the better insight into the mass- and heat-transfer processes, the pulsating ventilation can efficiently suppress dusting, i.e., improve the work environment, effectively combatdust expl osions in mines, and cut down power consumption of ventilation. The article shows that despite appreciable annual support of labor safety, the working conditions of mining personnel remain yet difficult. At the NUST MISIS Chair of Technosphere Safety, an experimental installation has been designed, which allows modeling dust content of mine air flows at the preset temperature and humidity. The article describes the structure and operation of the installation, as well as the brief experimentation procedure. The aim of the lab-scale tests is to study the influence of different air flow modes (including pulsating flow) on the processes of mass- and heat-transfer with a view to revealing mathematical relations at the initial stage. The article briefly describes the experimental program for 6 modes of ventilation. The planned theoretical and applied research in the form of the lab-scale testing at the initial stage enables formulating general knowledge and scientific–practical framework for a new school of pulsating ventilation of aerosols in mining. The general objective of the lab-scale experiments is the development of a technology for efficient abatement of toxic and hazardous effects, in the first turn, increased concentration of aerosol on mine performance.
