Information × Registration Number 0304U001133, 0102U006207 , R & D reports Title To execute technical and economic comparison of use on opencasts of the Volnlgorsk MIC space-saving excavator of the rotor SRs-1502, excavators of the rotor SRs-2000 and ER-5250 popup.stage_title "Виконати техніко-економічне порівняння використання на кар'єрах Вільногірського ГМК компактного роторного екскаватора SRs-1502 з перевантажувачем, роторних екскаваторів SRs-2000 і ЕР-5250" Head Kulish Vladislav, Registration Date 27-01-2004 Organization State research, enginerring and designing institute of coal industry "UkrNDIproect" popup.description2 Object of research are two excavator of the rotor SRs-2000 in updating on walk-rail to a course which differ productivity and are considered in structure of transport and transport-dumping complexes with reference to conditions Мotronovsko-Аnnovskogo of site Volnlgorsk of mountain - metallurgical combine the Purpose of research - calculation of productivity of dredges with reference to concrete conditions Мotronovsko-Аnnovskogo of site Volnlgorsk of mountain - metallurgical combine at total and selective dredging вскрышных breeds in volume 22,5 million in m3 (І a variant) and 12,5 million in m3 (ІІ a variant). It is established, that productivity of dredges SRs (ш)-2000 first updatings at their work in structure of transport (13,24 - 13,52 million in m3 one year) and т transport-dumping (13,88 - 14,25 million in m3 one year) complexes, at total dredging and stacking of breeds in отвал, is sufficient for performance of annual volume вскрышных works in 22 million. т also provides a necessary level of reservation - about 25 %. Productivity of dredges SRs (ш)-2000 second updatings at their work in structure of transport (10,13 - 10,30 million in m3 one year) and transport-dumping (10,66 - 10,95 million in m3 one year) complexes is too high for performance of volume mountain works in 12,5 million т - a level of reservation of 69 %. Productivity of dredges SRs-800 at their work in structure of transport (6,41 - 6,68 million in m3 one year) and transport-dumping (7,06 - 7,26 million in m3 one year) complexes, at total dredging and stacking of breeds in dump, is sufficient for performance of annual volume mining works in 12,5 million т and provides a level of reservation up to 10 %. Productivity of dredges at their work in structure transport-dumping a complex with selective dredging and stacking of breeds in dump is reduced insignificantly - on 2,76 % at SRs (ш)-2000 first updatings (13,49 - 13,87 million. m3), on 1,93 % at SRs (ш)-2000 second updatings (10,45 - 10,74 million in m3) and on 3,11 % at SRs-800 (6,84 - 7,03 million in m3).
