Abstract. The article is devoted to the investigation of the effect of new flame retardant compositions when applied to the wooden support of coal mines. Main object for developing new flame retardant compositions should be non-flammable, inexpensive, non-toxic substances and production wastes. Basing on theoretical and experimental studies with using DTA methods, X-ray diffraction analysis, and mechanism for formation of flame retardant coating of polystyrene for flame retardant compositions from liquid glass, a group of materials was selected, which, according to the above criteria, can be used as the main disperse fillers (at 20% and more): fly ash, blast furnace dust, burntrock, chamotte sand, asbestos cement waste, magnesite concentrate, building lime, etc. However, studies have shown that two-component flame retardant compositions, even with high fire-retardant properties, have a number of drawbacks (they are non-technological; fast sticking, pelletizing and setting, stacking from the surface), and they do not find practical application. Introduction of various additives (up to 1÷2% max) eliminates these drawbacks, improves technological properties of the composition, expands temperature range of application, effects formation of the fireproofcoating structure at the fire action.
Keywords: burning, temperature, thermal stream, heat conductivity, chemical transformations, wood, fire.
