苏联采矿工业露天采矿有5000多台单斗电铲。其中30％为-8型电铲,60％以上为-4.6型电铲。但是,这些电铲的时间利用率和功率利用率还不高。影响电铲利用指标的许多因素之一,是这些电铲的技术状况不佳,这与电铲的技术维护和检修组织工作的严密程度有关。在过去十年当中,苏联黑色冶金工业部矿业研究院对部属露天矿电铲使用情况的观 The Soviet mining industry has more than 5,000 open-cast mining shovel bucket. Of these, 30% are Type-8 shovels and over 60% are Type-4.6 shovels. However, these shovels have low time utilization and power utilization. One of the many factors that affect shovels utilization is the poor technical condition of these shovels, which is related to the rigor of the technical maintenance and overhaul organization of shovels. In the past ten years, the view of using the shovels of the subordinate open cast mines by the Mining Research Institute of the Soviet Union’s Black Metallurgical Industry
