The following parameters were taken into account: ambient temperature, humidity, gas composition and air pressure. It is established that the density of the gas mixture in an isolated space is an indicator of thermal processes. According to the results of the research, it was determined that in order to obtain improved electrical characteristics of carbonized organics and further evaluate their properties, it is promising to use mixtures (combinations) of materials with electrical parameters antagonistic to coal; it was found that the influence of hematite on the dynamics of electrical processes and electrical characteristics is more significant than that of magnetite; the peculiarities of the methodology for simulation modeling of inelastic deformation of polymer-reinforced rock masses, including: correct determination of the physical and mechanical properties of rocks required for calculations; construction of a structural geological scheme (thickness and sequence of rock layers. Based on classical ideas about the hydraulic characteristics of aqueous suspensions, theoretical formulas have been obtained that relate each of the characteristics to only one indicator - the density of the suspension or the bulk weight, which is easily measured in practice by weighing. Correlations between porosity, kinematic viscosity, and weight percentage of the solid phase and density were obtained for aqueous suspensions of man-made waste, such as fly ash, waste from iron ore plants, and basalt quarries. A model of the slurry formation process for the conditions of open-pit mining of placer deposits using hydraulic monitors was improved, which takes into account the mutual influence of the hydraulic resistance of the pipelines supplying liquid to the sump and to the hydraulic monitors Product Description popup.authors Ahaiev Ruslan A.
