The results of the work correspond to world standards of resource-saving, environmentally safe mining technologies, have investment attractiveness, are competitive and can be used in the mining industry in the scientific and practical justification of technological means of managing the quality of raw materials in the extraction of ores in deep horizons. In the work, a study was carried out and a functional analysis of the requirements of the world metallurgical industry for the quality of iron ores from underground mining in the mines of Ukraine was carried out. Grounded results of studies of the quality of raw materials and determination of the main influencing factors in the extraction of reflected ore from the treatment blocks. On the basis of the conducted research, new dependences of the quality of ore grinding were established, depending on the location schemes of the wells and the technology of drilling and blasting operations, taking into account the stress-deformed state of the massif at significant depths. New regularities of the influence of mountain pressure on indicators of output of reflected ore and the quality of mined raw materials were obtained. The influence of the shape and parameters of the compensation spaces on the quality indicators of the reflected ore has been established. Improved technologies for beneficiation of mined ores. Key words: underground development, iron ore, quality, tailings, release, stress-strain state. Product Description popup.authors Bondar Iryna H.
