近几年来,露天矿铁路运输对列车进行了重大的技术改造。运用大型的交流和直流电机车,载重量为230～240t 的翻斗车,提高了轴重并增加了运行速度。这就不仅要求改善运输作业工艺,而且要求改善运输线路,首先是改善工务段作业。为使结论客观,作者援引以巴卡尔矿务局为例的铁路运输的技术经济指标:铁路线的展线长度为155km;道岔的总数是270付;翻斗车的价值在1989年11月1日是516.2万卢布;机车的价值在1989年11月1日是947.1万卢布;运输线的价值在1989年11月1日是1006.6万卢布;大修和小修费用,按1988年资料,整条铁路线为7.61万卢布、道岔为30.9万卢布、摩
In recent years, open-pit railway transport on the train made a major technological transformation. The use of large AC and DC locomotives, dump trucks with a carrying capacity of 230 to 240 tons increase shaft weight and increase operating speed. This not only calls for improvements in transport operations, but also calls for improvements in transport routes, starting with the improvement of public works operations. In order to make the conclusion objective, the author invokes the technical and economic indicators of railway transportation, taking the Bakar Mining Bureau as an example: the length of the railway line is 155km; the total number of turnouts is 270; the value of dump trucks is on November 1, 1989 Is 5,162,000 rubles; the value of the locomotive is 9,471,000 rubles as of November 1, 1989; the value of the transportation line is 10,066,000 rubles as of November 1, 1989; the overhaul and minor repairs costs are based on the 1988 data and the entire railway line 7.61 million rubles, turnouts for 300,000 rubles, Morocco
