Project. popup.stage_title Head Kozlov Konstantin, Registration Date 22-06-2006 Organization Ukrainian Scientific Research and Disign Institute for Industrial Technology popup.description2 The subject of research is residual reserves of uranium ore under level 640 m at Vatutinskeh deposit of SE "Eastern Mining and Concentration Integrated Works". The objective of the effort is definition of the technical and technological decisions for the bottom levels reserves opening and mining in the floor of 640-820 m and technical and economic indices of the mining. Method of the research is analysis of the opening and mining ways and existing condition of mining operations at the mining enterprise operated. The results of the research include analysis of the opening and mining of the deposit by vertical shafts and inclined drift with group preparation and face line development of breakage blocks. The conditions of the inclined spiral drift advancing, sections of mining openings when self-propelled load-haul-dump and drilling units are used; volumes of capital mining operations during the opening and mining of the Vatutinskeh deposit's bottom levels are determined. The scientific novelty is in substantiation of expediency of Vatutinskeh deposit's bottom levels opening by inclined spiral drift using self-propelled load-haul-dump and drilling units. Social importance is in rational use of the Earth's interior at the expense of involving in operation of the Vatutinskeh deposit's residual reserves in the floor of 640-820 m. The results of the research effort will be used when working documentation is developed and the enterprise develops the Vatutinskeh deposit's bottom levels reserves of SE "Eastern Mining and Concentration Integrated Works". Predictive proposals for research subject development: the way of opening of the Vatutinskeh de-posit's bottom levels by inclined spiral drift is recommended for designing the ore deposits mining in the floor of 640-820 m.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
