Hrytsenko A. Improvement of methods and means for determining the content of useful components in the iron ore massif

Object - the process of interaction of electromagnetic fields and ionizing radiation with an array of rocks to determine the content of useful components of iron ore; goal - to improve methods and means of improving the accuracy of devices for determining the content of useful components (total iron and magnetite) in iron ore by synchronous use of the results of interaction of radiation and electromagnetic fields with rock and taking into account interfering factors; methods - a complex research method is applied, which includes theoretical and instrumental methods: planning of experiments, mathematical processing of their results; analysis of physicochemical composition of ores depending on variations of technological factors, theoretical generalizations using the theory of interaction of gamma radiation and electromagnetic fields with rocks, methods of mathematical, simulation and computer modeling, experimental research in laboratory and industrial conditions; results - substantiated and developed and synchronous method for determining the qualitative characteristics of iron ore, a method based on the use of scale factors and correlation between total iron and magnetite iron, developed a mathematical model for optimizing the geometry of the measuring zone selective gamma-gammaner method and developed the converter, the prototype of the combined downhole device is developed, the combined downhole sample is integrated into the structure of the mobile station, the approbation in the conditions of industrial production is carried out; introduced at the party of mine mining geophysics of the state enterprise "Ukrchormetgeologiya" and in the quarry of the mining and processing complex "Ukrmekhanobr" PJSC "ILYICH IRON AND STEEL WORKS"
