Abstract

The paper describes a common phenomenon that plays a leading role in ensuring the fire and explosion safety when working with dusts-and-gas mixtures, i.e. the hybrid mixtures. Historical background is provided as well as a description of the current state of the problem. The necessity of studying such mixtures is emphasized, such as, for coal basins. Worldwide applied methods of determining the blast parameters of hybrid mixtures, i.e. the maximum explosion pressure, lower concentration limit of the flame propagation, minimum explosive oxygen content and minimum phlegmatizing concentration of deterrent, are briefly discussed. A test setup is described which is recommended for use in the Russian Federation. The design of a fabricated setup is presented with the necessary additions. The results of experimental studies showing the need for further research are presented and the possibilities to apply such experimental setups in various industrial fields are described.

Keywords

Hybrid mixture, blast parameters, test setup, research into hybrid mixtures.
