Purpose of the work is research-and-development of seismically safe technology of ore mass preparation for in-situ leaching of beds 1, 4, 5, 10 in the level of 280-210 m of the Michurinskoyeh deposit. Methods of the research - analytical and mathematical, as well as analysis and estimation of the technologies of ore mass preparation with the set grain-size distribution; analysis of mining-and-geological and geomechanical conditions of mining of beds 1, 4, 5 and 10 in the level of 280-210 m of the Michurinskoyeh deposit. Results of the research are seismically safe parameters of ore breakage in compressed state and seismically safe technologies of ore mass preparation for in-situ leaching for mining and geological conditions of mining of beds 1, 4, 5, 10 in the level of 280-210 m of the Michurinskoyeh deposit. Scientific novelty - the limits of specific consumption of explosive substances are set for ore massif breakage in compressed state that averages 3.0 kg/cub. m at the coefficients of loosening 1.20-1.30 and strength according to M.M. Protod'yakonov - 14-18. Social importance - preparation of ore mass for in-situ leaching is provided, at that, the problems of underground and surface objects protection from seismic vibrations of underground explosions are solved. Mining of the metal is carried out in underground conditions that reduce the volumes of tail-ings of hydrometallurgical plant for storing them in tailings storage facilities on the surface. Results of the research will be used during ore mass preparation for in-situ leaching when beds 1, 4, 5 and 10 and residual reserves of the ore in the level of 280-210 m of the Michurinskoyeh deposit mined. Prospects proposals on development of the object of the research: the results of the research will be during development of the projects for mining of the residual reserves of the ores in the level of 280-210 m of the Michurinskoyeh deposit by in-situ leaching technologies, as well as at the mines of SE "VostGOK" and SE "Directsia". In-situ leaching, parameters of seismic vibrations, breakage in compressed state, mining massif, geo-technology, mining environment, deceleration. Product Description popup.authors Дудченко А.Х.
