One of the most important advantages of polyurethane foams is the ability to produce products in one step. Foaming and curing of this insulation does not require heat supply due to the exothermic synthesis reaction that occurs when two or more liquid components are mixed, with simultaneous adhesion of polyurethane foam to various surfaces due to good adhesion to almost any materials. At the same time, having a low density, this foam polymer is able to withstand fairly large loads. Samples were taken from the tailings filtration field of the Stoilensky GOK (Gubkin, Russia) from various sites as the studied raw materials, their granulometric and chemical compositions were determined, and the harmonic diameters of the filler particles were determined. Based on the calculation results, the dependence of the foaming coefficient on the average harmonic diameter of the filler was determined. An experiment planning matrix has been developed, based on the results of which mathematical models of the dependence of the coefficient of foaming of laboratory samples of polyurethane foam filled with tailings were built. Three zones of tailings are considered based on the results of sampling. Analyzing the results obtained, a quantitative and qualitative assessment of the influence of each factor separately, as well as their combination, on the change in the “composition–properties” system was derived.
